Pollution is the introduction of harmful materials into the environment . These harmful materials are called pollutants . Pollutants can be natural, such as volcanic ash . They can also be created by human activity, such as trash or runoff produced by factories. Pollutants damage the quality of air, water, and land. Many things that are useful to people produce pollution. Cars spew pollutants from their exhaust pipes. Burning coal to create electricity pollutes the air. Industries and homes generate garbage and sewage that can pollute the land and water. Pesticides —chemical poisons used to kill weeds and insects— seep into waterways and harm wildlife . All living things—from one-celled microbes to blue whales—depend on Earth ’s supply of air and water. When these resources are polluted, all forms of life are threatened. Pollution is a global problem. Although urban areas are usually more polluted than the countryside, pollution can spread to remote places where no people live. For example, pesticides and other chemicals have been found in the Antarctic ice sheet . In the middle of the northern Pacific Ocean, a huge collection of microscopic plastic particles forms what is known as the Great Pacific Garbage Patch . Air and water currents carry pollution. Ocean currents and migrating fish carry marine pollutants far and wide. Winds can pick up radioactive material accidentally released from a nuclear reactor and scatter it around the world. Smoke from a factory in one country drifts into another country. In the past, visitors to Big Bend National Park in the U.S. state of Texas could see 290 kilometers (180 miles) across the vast landscape . Now, coal-burning power plants in Texas and the neighboring state of Chihuahua, Mexico have spewed so much pollution into the air that visitors to Big Bend can sometimes see only 50 kilometers (30 miles). The three major types of pollution are air pollution , water pollution , and land pollution . Air Pollution Sometimes, air pollution is visible . A person can see dark smoke pour from the exhaust pipes of large trucks or factories, for example. More often, however, air pollution is invisible . Polluted air can be dangerous, even if the pollutants are invisible. It can make people’s eyes burn and make them have difficulty breathing. It can also increase the risk of lung cancer . Sometimes, air pollution kills quickly. In 1984, an accident at a pesticide plant in Bhopal, India, released a deadly gas into the air. At least 8,000 people died within days. Hundreds of thou sands more were permanently injured. Natural disasters can also cause air pollution to increase quickly. When volcanoes erupt , they eject volcanic ash and gases into the atmosphere . Volcanic ash can discolor the sky for months. After the eruption of the Indonesian volcano of Krakatoa in 1883, ash darkened the sky around the world. The dimmer sky caused fewer crops to be harvested as far away as Europe and North America. For years, meteorologists tracked what was known as the “equatorial smoke stream .” In fact, this smoke stream was a jet stream , a wind high in Earth’s atmosphere that Krakatoa’s air pollution made visible. Volcanic gases , such as sulfur dioxide , can kill nearby residents and make the soil infertile for years. Mount Vesuvius, a volcano in Italy, famously erupted in 79, killing hundreds of residents of the nearby towns of Pompeii and Herculaneum. Most victims of Vesuvius were not killed by lava or landslides caused by the eruption. They were choked, or asphyxiated , by deadly volcanic gases. In 1986, a toxic cloud developed over Lake Nyos, Cameroon. Lake Nyos sits in the crater of a volcano. Though the volcano did not erupt, it did eject volcanic gases into the lake. The heated gases passed through the water of the lake and collected as a cloud that descended the slopes of the volcano and into nearby valleys . As the toxic cloud moved across the landscape, it killed birds and other organisms in their natural habitat . This air pollution also killed thousands of cattle and as many as 1,700 people. Most air pollution is not natural, however. It comes from burning fossil fuels —coal, oil , and natural gas . When gasoline is burned to power cars and trucks, it produces carbon monoxide , a colorless, odorless gas. The gas is harmful in high concentrations , or amounts. City traffic produces highly concentrated carbon monoxide. Cars and factories produce other common pollutants, including nitrogen oxide , sulfur dioxide, and hydrocarbons . These chemicals react with sunlight to produce smog , a thick fog or haze of air pollution. The smog is so thick in Linfen, China, that people can seldom see the sun. Smog can be brown or grayish blue, depending on which pollutants are in it. Smog makes breathing difficult, especially for children and older adults. Some cities that suffer from extreme smog issue air pollution warnings. The government of Hong Kong, for example, will warn people not to go outside or engage in strenuous physical activity (such as running or swimming) when smog is very thick.

When air pollutants such as nitrogen oxide and sulfur dioxide mix with moisture, they change into acids . They then fall back to earth as acid rain . Wind often carries acid rain far from the pollution source. Pollutants produced by factories and power plants in Spain can fall as acid rain in Norway. Acid rain can kill all the trees in a forest . It can also devastate lakes, streams, and other waterways. When lakes become acidic, fish can’t survive . In Sweden, acid rain created thousands of “ dead lakes ,” where fish no longer live. Acid rain also wears away marble and other kinds of stone . It has erased the words on gravestones and damaged many historic buildings and monuments . The Taj Mahal , in Agra, India, was once gleaming white. Years of exposure to acid rain has left it pale. Governments have tried to prevent acid rain by limiting the amount of pollutants released into the air. In Europe and North America, they have had some success, but acid rain remains a major problem in the developing world , especially Asia. Greenhouse gases are another source of air pollution. Greenhouse gases such as carbon dioxide and methane occur naturally in the atmosphere. In fact, they are necessary for life on Earth. They absorb sunlight reflected from Earth, preventing it from escaping into space. By trapping heat in the atmosphere, they keep Earth warm enough for people to live. This is called the greenhouse effect . But human activities such as burning fossil fuels and destroying forests have increased the amount of greenhouse gases in the atmosphere. This has increased the greenhouse effect, and average temperatures across the globe are rising. The decade that began in the year 2000 was the warmest on record. This increase in worldwide average temperatures, caused in part by human activity, is called global warming . Global warming is causing ice sheets and glaciers to melt. The melting ice is causing sea levels to rise at a rate of two millimeters (0.09 inches) per year. The rising seas will eventually flood low-lying coastal regions . Entire nations, such as the islands of Maldives, are threatened by this climate change . Global warming also contributes to the phenomenon of ocean acidification . Ocean acidification is the process of ocean waters absorbing more carbon dioxide from the atmosphere. Fewer organisms can survive in warmer, less salty waters. The ocean food web is threatened as plants and animals such as coral fail to adapt to more acidic oceans. Scientists have predicted that global warming will cause an increase in severe storms . It will also cause more droughts in some regions and more flooding in others. The change in average temperatures is already shrinking some habitats, the regions where plants and animals naturally live. Polar bears hunt seals from sea ice in the Arctic. The melting ice is forcing polar bears to travel farther to find food , and their numbers are shrinking. People and governments can respond quickly and effectively to reduce air pollution. Chemicals called chlorofluorocarbons (CFCs) are a dangerous form of air pollution that governments worked to reduce in the 1980s and 1990s. CFCs are found in gases that cool refrigerators, in foam products, and in aerosol cans . CFCs damage the ozone layer , a region in Earth’s upper atmosphere. The ozone layer protects Earth by absorbing much of the sun’s harmful ultraviolet radiation . When people are exposed to more ultraviolet radiation, they are more likely to develop skin cancer, eye diseases, and other illnesses. In the 1980s, scientists noticed that the ozone layer over Antarctica was thinning. This is often called the “ ozone hole .” No one lives permanently in Antarctica. But Australia, the home of more than 22 million people, lies at the edge of the hole. In the 1990s, the Australian government began an effort to warn people of the dangers of too much sun. Many countries, including the United States, now severely limit the production of CFCs. Water Pollution Some polluted water looks muddy, smells bad, and has garbage floating in it. Some polluted water looks clean, but is filled with harmful chemicals you can’t see or smell. Polluted water is unsafe for drinking and swimming. Some people who drink polluted water are exposed to hazardous chemicals that may make them sick years later. Others consume bacteria and other tiny aquatic organisms that cause disease. The United Nations estimates that 4,000 children die every day from drinking dirty water. Sometimes, polluted water harms people indirectly. They get sick because the fish that live in polluted water are unsafe to eat. They have too many pollutants in their flesh. There are some natural sources of water pollution. Oil and natural gas, for example, can leak into oceans and lakes from natural underground sources. These sites are called petroleum seeps . The world’s largest petroleum seep is the Coal Oil Point Seep, off the coast of the U.S. state of California. The Coal Oil Point Seep releases so much oil that tar balls wash up on nearby beaches . Tar balls are small, sticky pieces of pollution that eventually decompose in the ocean.

Human activity also contributes to water pollution. Chemicals and oils from factories are sometimes dumped or seep into waterways. These chemicals are called runoff. Chemicals in runoff can create a toxic environment for aquatic life. Runoff can also help create a fertile environment for cyanobacteria , also called blue-green algae . Cyanobacteria reproduce rapidly, creating a harmful algal bloom (HAB) . Harmful algal blooms prevent organisms such as plants and fish from living in the ocean. They are associated with “ dead zones ” in the world’s lakes and rivers, places where little life exists below surface water. Mining and drilling can also contribute to water pollution. Acid mine drainage (AMD) is a major contributor to pollution of rivers and streams near coal mines . Acid helps miners remove coal from the surrounding rocks . The acid is washed into streams and rivers, where it reacts with rocks and sand. It releases chemical sulfur from the rocks and sand, creating a river rich in sulfuric acid . Sulfuric acid is toxic to plants, fish, and other aquatic organisms. Sulfuric acid is also toxic to people, making rivers polluted by AMD dangerous sources of water for drinking and hygiene . Oil spills are another source of water pollution. In April 2010, the Deepwater Horizon oil rig exploded in the Gulf of Mexico, causing oil to gush from the ocean floor. In the following months, hundreds of millions of gallons of oil spewed into the gulf waters. The spill produced large plumes of oil under the sea and an oil slick on the surface as large as 24,000 square kilometers (9,100 square miles). The oil slick coated wetlands in the U.S. states of Louisiana and Mississippi, killing marsh plants and aquatic organisms such as crabs and fish. Birds, such as pelicans , became coated in oil and were unable to fly or access food. More than two million animals died as a result of the Deepwater Horizon oil spill. Buried chemical waste can also pollute water supplies. For many years, people disposed of chemical wastes carelessly, not realizing its dangers. In the 1970s, people living in the Love Canal area in Niagara Falls, New York, suffered from extremely high rates of cancer and birth defects . It was discovered that a chemical waste dump had poisoned the area’s water. In 1978, 800 families living in Love Canal had to a bandon their homes. If not disposed of properly, radioactive waste from nuclear power plants can escape into the environment. Radioactive waste can harm living things and pollute the water. Sewage that has not been properly treated is a common source of water pollution. Many cities around the world have poor sewage systems and sewage treatment plants. Delhi, the capital of India, is home to more than 21 million people. More than half the sewage and other waste produced in the city are dumped into the Yamuna River. This pollution makes the river dangerous to use as a source of water for drinking or hygiene. It also reduces the river’s fishery , resulting in less food for the local community. A major source of water pollution is fertilizer used in agriculture . Fertilizer is material added to soil to make plants grow larger and faster. Fertilizers usually contain large amounts of the elements nitrogen and phosphorus , which help plants grow. Rainwater washes fertilizer into streams and lakes. There, the nitrogen and phosphorus cause cyanobacteria to form harmful algal blooms. Rain washes other pollutants into streams and lakes. It picks up animal waste from cattle ranches. Cars drip oil onto the street, and rain carries it into storm drains , which lead to waterways such as rivers and seas. Rain sometimes washes chemical pesticides off of plants and into streams. Pesticides can also seep into groundwater , the water beneath the surface of the Earth. Heat can pollute water. Power plants, for example, produce a huge amount of heat. Power plants are often located on rivers so they can use the water as a coolant . Cool water circulates through the plant, absorbing heat. The heated water is then returned to the river. Aquatic creatures are sensitive to changes in temperature. Some fish, for example, can only live in cold water. Warmer river temperatures prevent fish eggs from hatching. Warmer river water also contributes to harmful algal blooms. Another type of water pollution is simple garbage. The Citarum River in Indonesia, for example, has so much garbage floating in it that you cannot see the water. Floating trash makes the river difficult to fish in. Aquatic animals such as fish and turtles mistake trash, such as plastic bags, for food. Plastic bags and twine can kill many ocean creatures. Chemical pollutants in trash can also pollute the water, making it toxic for fish and people who use the river as a source of drinking water. The fish that are caught in a polluted river often have high levels of chemical toxins in their flesh. People absorb these toxins as they eat the fish. Garbage also fouls the ocean. Many plastic bottles and other pieces of trash are thrown overboard from boats. The wind blows trash out to sea. Ocean currents carry plastics and other floating trash to certain places on the globe, where it cannot escape. The largest of these areas, called the Great Pacific Garbage Patch, is in a remote part of the Pacific Ocean. According to some estimates, this garbage patch is the size of Texas. The trash is a threat to fish and seabirds, which mistake the plastic for food. Many of the plastics are covered with chemical pollutants. Land Pollution Many of the same pollutants that foul the water also harm the land. Mining sometimes leaves the soil contaminated with dangerous chemicals. Pesticides and fertilizers from agricultural fields are blown by the wind. They can harm plants, animals, and sometimes people. Some fruits and vegetables absorb the pesticides that help them grow. When people consume the fruits and vegetables, the pesticides enter their bodies. Some pesticides can cause cancer and other diseases. A pesticide called DDT (dichlorodiphenyltrichloroethane) was once commonly used to kill insects, especially mosquitoes. In many parts of the world, mosquitoes carry a disease called malaria , which kills a million people every year. Swiss chemist Paul Hermann Muller was awarded the Nobel Prize for his understanding of how DDT can control insects and other pests. DDT is responsible for reducing malaria in places such as Taiwan and Sri Lanka. In 1962, American biologist Rachel Carson wrote a book called Silent Spring , which discussed the dangers of DDT. She argued that it could contribute to cancer in humans. She also explained how it was destroying bird eggs, which caused the number of bald eagles, brown pelicans, and ospreys to drop. In 1972, the United States banned the use of DDT. Many other countries also banned it. But DDT didn’t disappear entirely. Today, many governments support the use of DDT because it remains the most effective way to combat malaria. Trash is another form of land pollution. Around the world, paper, cans, glass jars, plastic products, and junked cars and appliances mar the landscape. Litter makes it difficult for plants and other producers in the food web to create nutrients . Animals can die if they mistakenly eat plastic. Garbage often contains dangerous pollutants such as oils, chemicals, and ink. These pollutants can leech into the soil and harm plants, animals, and people. Inefficient garbage collection systems contribute to land pollution. Often, the garbage is picked up and brought to a dump, or landfill . Garbage is buried in landfills. Sometimes, communities produce so much garbage that their landfills are filling up. They are running out of places to dump their trash. A massive landfill near Quezon City, Philippines, was the site of a land pollution tragedy in 2000. Hundreds of people lived on the slopes of the Quezon City landfill. These people made their living from recycling and selling items found in the landfill. However, the landfill was not secure. Heavy rains caused a trash landslide, killing 218 people. Sometimes, landfills are not completely sealed off from the land around them. Pollutants from the landfill leak into the earth in which they are buried. Plants that grow in the earth may be contaminated, and the herbivores that eat the plants also become contaminated. So do the predators that consume the herbivores. This process, where a chemical builds up in each level of the food web, is called bioaccumulation . Pollutants leaked from landfills also leak into local groundwater supplies. There, the aquatic food web (from microscopic algae to fish to predators such as sharks or eagles) can suffer from bioaccumulation of toxic chemicals. Some communities do not have adequate garbage collection systems, and trash lines the side of roads. In other places, garbage washes up on beaches. Kamilo Beach, in the U.S. state of Hawai'i, is littered with plastic bags and bottles carried in by the tide . The trash is dangerous to ocean life and reduces economic activity in the area. Tourism is Hawai'i’s largest industry . Polluted beaches discourage tourists from investing in the area’s hotels, restaurants, and recreational activities. Some cities incinerate , or burn, their garbage. Incinerating trash gets rid of it, but it can release dangerous heavy metals and chemicals into the air. So while trash incinerators can help with the problem of land pollution, they sometimes add to the problem of air pollution. Reducing Pollution Around the world, people and governments are making efforts to combat pollution. Recycling, for instance, is becoming more common. In recycling, trash is processed so its useful materials can be used again. Glass, aluminum cans, and many types of plastic can be melted and reused . Paper can be broken down and turned into new paper. Recycling reduces the amount of garbage that ends up in landfills, incinerators, and waterways. Austria and Switzerland have the highest recycling rates. These nations recycle between 50 and 60 percent of their garbage. The United States recycles about 30 percent of its garbage. Governments can combat pollution by passing laws that limit the amount and types of chemicals factories and agribusinesses are allowed to use. The smoke from coal-burning power plants can be filtered. People and businesses that illegally dump pollutants into the land, water, and air can be fined for millions of dollars. Some government programs, such as the Superfund program in the United States, can force polluters to clean up the sites they polluted. International agreements can also reduce pollution. The Kyoto Protocol , a United Nations agreement to limit the emission of greenhouse gases, has been signed by 191 countries. The United States, the world’s second-largest producer of greenhouse gases, did not sign the agreement. Other countries, such as China, the world’s largest producer of greenhouse gases, have not met their goals. Still, many gains have been made. In 1969, the Cuyahoga River, in the U.S. state of Ohio, was so clogged with oil and trash that it caught on fire. The fire helped spur the Clean Water Act of 1972. This law limited what pollutants could be released into water and set standards for how clean water should be. Today, the Cuyahoga River is much cleaner. Fish have returned to regions of the river where they once could not survive. But even as some rivers are becoming cleaner, others are becoming more polluted. As countries around the world become wealthier, some forms of pollution increase. Countries with growing economies usually need more power plants, which produce more pollutants. Reducing pollution requires environmental, political, and economic leadership. Developed nations must work to reduce and recycle their materials, while developing nations must work to strengthen their economies without destroying the environment. Developed and developing countries must work together toward the common goal of protecting the environment for future use.

How Long Does It Last? Different materials decompose at different rates. How long does it take for these common types of trash to break down?

  • Paper: 2-4 weeks
  • Orange peel: 6 months
  • Milk carton: 5 years
  • Plastic bag: 15 years
  • Tin can: 100 years
  • Plastic bottle: 450 years
  • Glass bottle: 500 years
  • Styrofoam: Never

Indoor Air Pollution The air inside your house can be polluted. Air and carpet cleaners, insect sprays, and cigarettes are all sources of indoor air pollution.

Light Pollution Light pollution is the excess amount of light in the night sky. Light pollution, also called photopollution, is almost always found in urban areas. Light pollution can disrupt ecosystems by confusing the distinction between night and day. Nocturnal animals, those that are active at night, may venture out during the day, while diurnal animals, which are active during daylight hours, may remain active well into the night. Feeding and sleep patterns may be confused. Light pollution also indicates an excess use of energy. The dark-sky movement is a campaign by people to reduce light pollution. This would reduce energy use, allow ecosystems to function more normally, and allow scientists and stargazers to observe the atmosphere.

Noise Pollution Noise pollution is the constant presence of loud, disruptive noises in an area. Usually, noise pollution is caused by construction or nearby transportation facilities, such as airports. Noise pollution is unpleasant, and can be dangerous. Some songbirds, such as robins, are unable to communicate or find food in the presence of heavy noise pollution. The sound waves produced by some noise pollutants can disrupt the sonar used by marine animals to communicate or locate food.

Essay on Pollution

An essay on pollution is an essential concept for students as it reveals the consequences of human activities on the environment. Read on to explore how to write an intriguing and engaging essay on pollution.

Essay on Pollution – Important Guidelines

Please consider adopting the following suggestions when writing an essay on pollution. Moreover, these suggestions will be helpful for most other essays as well.

  • Begin with an introductory paragraph, preferably highlighting the history or insight of the topic.
  • Try to avoid jargon unless the topic demands so.
  • Use bulleted points to present content wherever possible
  • Incorporate factual data, such as dates, names and places wherever possible.
  • Avoid writing a large monotonous block of text. Always break up the content into easily digestible chunks
  • Try to conclude the essay with a closing paragraph.

Essay on Pollution – Sample 1

Pollution had existed long before humans evolved. For instance, volcanic eruptions commonly pumped massive amounts of sulphur dioxide into the atmosphere, causing acid rain. The greenhouse gas, ozone, forms from natural, photochemical reactions in the atmosphere. 

However, significant levels of pollution occurred only after the Industrial Revolution, when untreated exhausts and toxic waste products were released into the environment. Air pollution was rampant, with thick, toxic smog covering most towns and cities. Water pollution affected many water bodies. Toxic substances leached into the soil, hampering the soil quality.

Today, there have been many measures to curb the effects of pollution, but its repercussions can still be observed. For instance, the land and sea ice near the poles have been decreasing at an alarming rate. This has led to the debate regarding climatic factors and their impact on our environment. There was a time when lead used to be added to motor fuel. This substance, combined with the world’s increasing demand for motor vehicles, caused a spike in air pollution. What made this air pollution more dangerous is the fact that the air had high levels of lead.

Lead is toxic and can cause a vast array of health problems. The most common illnesses are neurological in nature. Lead can also travel through the placenta, between a mother and her unborn child. Moreover, young children and infants are even more sensitive to lead. They can develop learning deficits, behavioural problems and also a low IQ.

Furthermore, some studies have arrived at a “lead-crime postulate”, where children who were exposed to high levels of lead were more likely to indulge in criminal activities. This correlation was made as to the crime rates during the 1980s, and early 1990s were rather high. Lead can also cause neurological effects on vertebrates and impair the reproductive capabilities of plants. More ominously, lead can be absorbed into the tissues of such organisms, and they can pass it on to us when we consume them.

Technological progress also brings newer forms of pollution. Radioactive pollution is one of the rarer types of pollution. This type of pollution occurs naturally as well – elements such as uranium and thorium are present in rocks and soil. Carbon-14 is a radioactive isotope of carbon naturally present in all living organisms. It is created by cosmic rays. However, these natural sources of radiation are of little concern. Only anthropogenic sources of radioactivity are considered lethal sources of pollution. For instance, the Chernobyl nuclear disaster is the most publicised nuclear disaster ever to occur. The total death count was documented to be at 16,000. However, unofficial reports indicated that the death toll was much higher. Most deaths occurred due to acute radiation poisoning and many other deaths were caused due to radioactivity-induced cancer. Though it has been more than a few decades, radioactivity still persists around the site of the nuclear reactor. Efforts to contain the radioactivity included building the Shelter Structure, more popularly known as the “sarcophagus”. It was built in December 1986 and enclosed the reactor, preventing radiation from leaking through the building. 

Though the levels of pollution have dropped down since the industrial revolution, we still see many repercussions to this day. Following are some extreme cases of pollution caused by anthropological activities.

The Great Smog of London was a severe case of air pollution that occurred in 1952. The event caused massive disruption by severely affecting visibility. It also caused a variety of respiratory illnesses in 1,00,000 individuals and the death of over 4,000 as a direct result of the smog. 

In India, pollution is even more rampant. Delhi has recorded one of the worst cases of air pollution, with the air rated as “hazardous” in November 2017.

Environmental Pollution: Causes and Consequences Essay

  • As a template for you assignment

Environmental pollution is the unwarranted discharge of mass or energy into the planet’s natural resource pools, such as land, air, or water, which detriments the environment’s ecological stability and the health of the living things that inhabit it. There is an intensified health risk and pollution in middle and low-income countries due to the increased use of pesticides, industrialization, the introduction of nitrogen-based fertilizers, forest fires, urbanization, and inadequate waste management (Appannagari, 2017). Air pollution, lead and chemicals exposure, hazardous waste exposure, and inappropriate e-waste disposal all result in unfavorable living conditions, fatal illnesses, and ecosystem destruction. The essay will provide an overview of pollution and proffer solutions to combating pollution for a sustainable environment and health.

In addition to hindering economic development and considerably accelerating climate change, pollution exacerbates poverty and inequality in urban and rural areas. The most pain is always experienced by the poor, who cannot afford to protect themselves against pollution’s harmful effects. The main environmental factor contributing to sickness and early mortality is pollution due to premature deaths resulting from pollution (Appannagari, 2017). Due to the unacceptably high cost to human capital and health, as well as the resulting GDP losses, pollution must be addressed. Through initiatives like reducing black carbon and methane emissions, which are responsible for air pollution and climate change, pollution management can also significantly contribute to climate change mitigation (Appannagari, 2017). Additionally, pollution control can promote competitiveness through, for instance, job growth, increased energy efficiency, better transportation, and sustainable urban and rural development. Below are the various approaches for solutions to health and pollution problems.

First, governments should evaluate pollution as a national and international priority and integrate it into the city and country planning process. Pollution affects the health and well-being of societies and, as such, cannot be solely viewed as an environmental issue (The Lancet Commission on Pollution and Health, 2017). All levels of government should give pollution prevention a high priority, incorporate it into development planning, and tie it to commitments regarding climate change, SDGs, and the prevention of non-communicable diseases. Some options are both affordable and offer good returns on investment.

Secondly, governments should increase funding for pollution control and prioritize it by health impacts. There should be a significant increase in the financing for pollution management in low- and middle-income nations, both from national budgets and international development organizations (The Lancet Commission on Pollution and Health, 2017). The most effective international support for pollution reduction is when it mobilizes additional actions and funding from others. Examples include helping towns and nations that are quickly industrializing concerning technical capacity building, regulatory and enforcement support, and support for direct actions to save lives. Monitoring financing initiatives are necessary to determine their cost-effectiveness and to raise accountability.

Thirdly, organizations should work to build multicultural partnerships for pollution control. Public-private partnerships and interagency cooperation can be powerful tools in creating clean technology and energy sources that will ultimately prevent pollution at its source (The Lancet Commission on Pollution and Health, 2017). Collaborations between ministries that include the ministries of finance, energy, development, agriculture, and transport, as well as the ministries of health and the environment, are crucial in pollution control. Governments should promote monitoring systems that could identify and apportion pollution sources, measure pollution levels, guide enforcement, and assess progress toward goals. The use of new technology in pollution monitoring, such as data mining and satellite images, can boost effectiveness, broaden the monitoring area, and cut costs.

One of the main issues facing the world in the current period is pollution. Natural resources are depleting daily due to car emissions, new technologies, factories, and chemicals added to food. All of these factors seriously harm the world. However, the problems caused by pollution can be prevented by building multicultural partnerships, increasing funding for pollution control, integrating it into the country’s planning process, and adopting new technology for monitoring pollution. Preventing pollution lowers the cost to the environment and the economy.

What is An Environmental Pollution Essay?

Environmental pollution is a massive global threat affecting animals, humans, and nature in unprecedented ways.

Environmental Pollution Essay Introduction Sample

Environmental pollution is one of planet earth’s biggest threats. Harmful substances released into the environment leave a negative impact. Pollution affects the quality of human life more than we can imagine. Corrosion of soil, death of animals and plants, respiratory diseases, haze, smog, and acid rain are some of the effects of this menace. Over the years, the government has tried to fight environmental pollution, but individual efforts can also play a big part. Individuals can start by properly disposing waste, replacing plastic bags with cloth bags for shopping, and conversing water.

Environmental pollution is a huge problem. It involves the introduction of harmful substances called pollutants into the environment. Pollutants are commonly from human activities like industrialization, urbanization, and transportation. Natural factors like volcanic eruptions and storms also readily contribute to environmental pollution. Human-induced pollution forms the bulk of pollution in modern times. Pollution threatens the environment, life, and health of humans, plants, and animals. Living species cannot survive without clean and pure air, which is why we must all work to keep the environment healthy. 

Pollution of the environment is a severe problem today. Human activities release harmful toxins into the environment, degrading the natural environment and upsetting the ecosystem balance. Cutting down trees and forests, dumping industrial waste, and using plastic are also human-induced causes of pollution. Pollution leads to species and plants’ deaths, the ecosystem’s ruin, and health problems like asthma and cancer. We must fight against this problem if we want clean air, water, and earth.

Pollution of the environment has produced many destructive problems, such as the buildup of waste matter in the ocean. Plastic and chemicals threaten and alter the balance of the ecosystem. Global warming, flood, acid rain, species depletion, and famines are some consequences of pollution. We must take urgent action to prevent environmental pollution and keep the planet green and inhabitable.

Consequences of Pollution

The consequences of pollution are severe and far-reaching. Air pollution is a major contributor to respiratory diseases, including asthma and chronic obstructive pulmonary disease (COPD). Long-term exposure to air pollutants such as particulate matter and nitrogen dioxide has been linked to cardiovascular diseases and adverse pregnancy outcomes.

Water pollution poses threats to aquatic life and human health. Contaminated water sources can lead to the spread of waterborne diseases, affecting millions of people globally. Soil pollution affects plant growth and food safety, as pollutants like pesticides and heavy metals accumulate in the soil and enter the food chain.

Noise pollution can have physiological and psychological effects, causing stress, sleep disturbances, and an increased risk of cardiovascular diseases. Light pollution disrupts natural ecosystems and interferes with the behavior of nocturnal animals, affecting their reproductive patterns and migration.

Global Impact

Pollution is not confined to local or regional boundaries; it has a global impact. Greenhouse gas emissions, primarily from the burning of fossil fuels, contribute to global warming and climate change. The rise in global temperatures leads to melting ice caps, rising sea levels, and extreme weather events, posing threats to unsafe ecosystems and communities.

The pollution of oceans with plastic waste has become a global crisis, with millions of tons of plastic entering the oceans annually. This not only harms marine life but also affects human health, as microplastics enter the food chain through seafood consumption.

Loss of biodiversity is another consequence of pollution, as ecosystems are disrupted and species face habitat destruction and pollution-induced stress. The decline of pollinators, such as bees, due to exposure to pesticides, has implications for agriculture and food security.

Addressing Pollution

Addressing pollution requires a comprehensive and collaborative approach at individual, community, and governmental levels. Individuals can contribute by adopting sustainable practices in their daily lives, such as reducing energy consumption, using eco-friendly products, and practicing responsible waste disposal.

Communities can organize clean-up initiatives, promote recycling programs, and raise awareness about the importance of environmental conservation. Educational institutions play a crucial role in fostering environmental awareness and sustainability practices among students.

Governments must enact and enforce stringent environmental regulations to curb pollution. Incentives for industries to adopt cleaner technologies, invest in renewable energy sources, and implement sustainable waste management practices are essential. International cooperation is crucial to address global environmental challenges, with countries working together to reduce greenhouse gas emissions, combat plastic pollution, and protect biodiversity.

Essay on Environmental Pollution

The environment is the surrounding of an organism. The environment in which an organism lives is made up of various components like air, water, land, etc. These components are found in fixed proportions to create a harmonious balance in the environment for the organism to live in. Any kind of undesirable and unwanted change in the proportions of these components can be termed as pollution. This issue is increasing with every passing year. It is an issue that creates economic, physical, and social troubles. The environmental problem that is worsening with each day needs to be addressed so that its harmful effects on humans as well as the planet can be discarded.

Causes of Environmental Pollution 

With the rise of the industries and the migration of people from villages to cities in search of employment, there has been a regular increase in the problem of proper housing and unhygienic living conditions. These reasons have given rise to factors that cause pollution. 

Environmental pollution is of five basic types namely, Air, Water, Soil, and Noise pollution. 

Air Pollution: Air pollution is a major issue in today’s world. The smoke pouring out of factory chimneys and automobiles pollute the air that we breathe in. Gases like carbon dioxide, carbon monoxide, and sulphur dioxide are emitted with this smoke which mixes with air and causes great harm to the human body, flora, and fauna. The dry-farm waste, dry grass, leaves, and coal used as domestic fuels in our villages also produce harmful gases. Acid rain occurs due to an excess of sulphur dioxide in the air.

The Main Sources of Air Pollution are as Follows:  

Automobile pollution 

Industrial air pollution 

Burning garbage 

Brick kilns 

Indoor air pollution 

Decomposed animals and plants 

Radioactive elements

Water Pollution: Water pollution is one of the most serious environmental issues. The waste products from the growing industries and sewage water are not treated properly before disposing of the wastewater into the rivers and other water bodies, thus leading to water pollution. Agricultural processes with excess fertilizers and pesticides also pollute the water bodies. 

The Main Sources of Water Pollution as Follows:  

Marine commerce. 

Industrial effluents joining seas and oceans. 

Dumping of radioactive substances into seawater. 

Sewage is disposed of into the sea by rivers. 

Offshore oil rigs. 

Recreational activities. 

Agricultural pollutants are disposed of into the water bodies.

  

Soil or Land Pollution: Soil pollution or land pollution results from the deposition of solid waste, accumulation of biodegradable material, deposition of chemicals with poisonous chemical compositions, etc on the open land. Waste materials such as plastics, polythene, and bottles, cause land pollution and render the soil infertile. Moreover, the dumping of dead bodies of animals adds to this issue. Soil pollution causes several diseases in man and animals like Cholera, Dysentery, Typhoid, etc.

The Main Causes of Soil Pollution are as Follows:  

Industrial waste 

Urban commercial and domestic waste 

Chemical fertilizers 

Biomedical waste 

Noise Pollution: With an increasing population, urbanization, and industrialization, noise pollution is becoming a serious form of pollution affecting human life, health, and comfort in daily life. Horns of vehicles, loudspeakers, music systems, and industrial activities contribute to noise pollution. 

The Main Sources of Noise Pollution as Follows:  

The machines in the factories and industries produce whistling sounds, crushing noise, and thundering sounds. 

Loudspeakers, horns of vehicles. 

Blasting of rocks and earth, drilling tube wells, ventilation fans, and heavy earth-moving machinery at construction sites.

How Pollution Harms Health and Environment

The lives of people and other creatures are affected by environmental pollution, both directly and indirectly. For centuries, these living organisms have coexisted with humans on the planet. 

1. Effect on the Environment

Smog is formed when carbon and dust particles bind together in the air, causing respiratory problems, haze, and smoke. These are created by the combustion of fossil fuels in industrial and manufacturing facilities and vehicle combustion of carbon fumes. 

Furthermore, these factors impact the immune systems of birds, making them carriers of viruses and diseases. It also has an impact on the body's system and organs. 

2.  Land, Soil, and Food Effects 

The degradation of human organic and chemical waste harms the land and soil. It also releases chemicals into the land and water. Pesticides, fertilisers, soil erosion, and crop residues are the main causes of land and soil pollution. 

3. Effects on water 

Water is easily contaminated by any pollutant, whether it be human waste or factory chemical discharge. We also use this water for crop irrigation and drinking. They, too, get polluted as a result of infection. Furthermore, an animal dies as a result of drinking the same tainted water. 

Furthermore, approximately 80% of land-based pollutants such as chemical, industrial, and agricultural waste wind up in water bodies. 

Furthermore, because these water basins eventually link to the sea, they contaminate the sea's biodiversity indirectly. 

4. Food Reaction

Crops and agricultural produce become poisonous as a result of contaminated soil and water. These crops are laced with chemical components from the start of their lives until harvest when they reach a mass level. Due to this, tainted food has an impact on our health and organs. 

5. Climate Change Impact 

Climate change is also a source of pollution in the environment. It also has an impact on the ecosystem's physical and biological components. 

Ozone depletion, greenhouse gas emissions, and global warming are all examples of environmental pollution. Because these water basins eventually link to the sea, they contaminate the sea's biodiversity indirectly. Furthermore, their consequences may be fatal for future generations. The unpredictably cold and hot climate impacts the earth’s natural system. 

Furthermore, earthquakes, starvation, smog, carbon particles, shallow rain or snow, thunderstorms, volcanic eruptions, and avalanches are all caused by climate change, caused entirely by environmental pollution.

How to Minimise Environmental Pollution? 

To minimise this issue, some preventive measures need to be taken. 

Principle of 3R’s: To save the environment, use the principle of 3 R’s; Reuse, Reduce and Recycle. 

Reuse products again and again. Instead of throwing away things after one use, find a way to use them again.  Reduce the generation of waste products.  

Recycle: Paper, plastics, glass, and electronic items can be processed into new products while using fewer natural resources and lesser energy. 

To prevent and control air pollution, better-designed equipment, and smokeless fuels should be used in homes and industries. More and more trees should be planted to balance the ecosystem and control greenhouse effects. 

Noise pollution can be minimised by better design and proper maintenance of vehicles. Industrial noise can be reduced by soundproofing equipment like generators, etc.  

To control soil pollution, we must stop the usage of plastic. Sewage should be treated properly before using it as fertilizers and as landfills. Encourage organic farming as this process involves the use of biological materials and avoiding synthetic substances to maintain soil fertility and ecological balance. 

Several measures can be adopted to control water pollution. Some of them are water consumption and usage that can be minimized by altering the techniques involved. Water should be reused with treatment. 

The melting icebergs in Antarctica resulted in rising sea levels due to the world's environmental pollution, which had become a serious problem due to global warming, which had become a significant concern. Rising carbon pollution poses a risk for causing natural disasters such as earthquakes, cyclones, and other natural disasters. 

The Hiroshima-Nagasaki and Chernobyl disasters in Russia have irreversibly harmed humanity. Different countries around the world are responding to these calamities in the most effective way possible. 

Different countries around the world are responding to these calamities in the most effective way possible. More public awareness campaigns are being established to educate people about the hazards of pollution and the importance of protecting our environment. Greener lifestyles are becoming more popular; for example, energy-efficient lighting, new climate-friendly autos, and the usage of wind and solar power are just a few examples. 

Governments emphasise the need to plant more trees, minimise the use of plastics, improve natural waste recovery, and reduce pesticide use. This ecological way of living has helped humanity save other creatures from extinction while making the Earth a greener and safer ecology. 

 Conclusion

It is the responsibility of every individual to save our planet from these environmental contamination agents. If preventive measures are not taken then our future generation will have to face major repercussions. The government is also taking steps to create public awareness. Every individual should be involved in helping to reduce and control pollution.

introduction of pollution essay

by Chris Woodford . Last updated: November 22, 2022.

Photo: Air pollution is obvious when it pours from a smokestack (chimney), but it's not always so easy to spot. This is an old photo of the kind of smoke that used to come from coal-fired power plants and, apart from soot (unburned carbon particles), its pollutants include sulfur dioxide and the greenhouse gas carbon dioxide. Thanks to tougher pollution controls, modern power plants produce only a fraction as much pollution. Modern pollution made by traffic consists of gases like nitrogen dioxide and "particulates" (microscopic soot and dust fragments) that are largely invisible.

What is air pollution?

Air pollution is a gas (or a liquid or solid dispersed through ordinary air) released in a big enough quantity to harm the health of people or other animals, kill plants or stop them growing properly, damage or disrupt some other aspect of the environment (such as making buildings crumble), or cause some other kind of nuisance (reduced visibility, perhaps, or an unpleasant odor).

Natural air pollution

Photo: Forest fires are a completely natural cause of air pollution. We'll never be able to prevent them breaking out or stop the pollution they cause; our best hope is to manage forests, where we can, so fires don't spread. Ironically, that can mean deliberately burning areas of forest, as shown here, to create firebreaks. Forests are also deliberately burned to regenerate ecosystems. Photo by courtesy of US Fish and Wildlife Service .

Top-ten kinds of air pollution Photo: Flying molecules—if you could see air pollution close up, this is what it would look like. Image courtesy of US Department of Energy. Any gas could qualify as pollution if it reached a high enough concentration to do harm. Theoretically, that means there are dozens of different pollution gases. It's important to note that not all the things we think of as pollution are gases: some are aerosols (liquids or solids dispersed through gases). In practice, about ten different substances cause most concern: Sulfur dioxide : Coal, petroleum, and other fuels are often impure and contain sulfur as well as organic (carbon-based) compounds. When sulfur (spelled "sulphur" in some countries) burns with oxygen from the air, sulfur dioxide (SO 2 ) is produced. Coal-fired power plants are the world's biggest source of sulfur-dioxide air pollution, which contributes to smog, acid rain, and health problems that include lung disease. [5] Large amounts of sulfur dioxide are also produced by ships, which use dirtier diesel fuel than cars and trucks. [6] Carbon monoxide : This highly dangerous gas forms when fuels have too little oxygen to burn completely. It spews out in car exhausts and it can also build up to dangerous levels inside your home if you have a poorly maintained gas boiler , stove, or fuel-burning appliance. (Always fit a carbon monoxide detector if you burn fuels indoors.) [7] Carbon dioxide : This gas is central to everyday life and isn't normally considered a pollutant: we all produce it when we breathe out and plants such as crops and trees need to "breathe" it in to grow. However, carbon dioxide is also a greenhouse gas released by engines and power plants. Since the beginning of the Industrial Revolution, it's been building up in Earth's atmosphere and contributing to the problem of global warming and climate change . [8] Nitrogen oxides : Nitrogen dioxide (NO 2 ) and nitrogen oxide (NO) are pollutants produced as an indirect result of combustion, when nitrogen and oxygen from the air react together. Nitrogen oxide pollution comes from vehicle engines and power plants, and plays an important role in the formation of acid rain, ozone and smog. Nitrogen oxides are also "indirect greenhouse gases" (they contribute to global warming by producing ozone, which is a greenhouse gas). [9] Volatile organic compounds (VOCs) : These carbon-based (organic) chemicals evaporate easily at ordinary temperatures and pressures, so they readily become gases. That's precisely why they're used as solvents in many different household chemicals such as paints , waxes, and varnishes. Unfortunately, they're also a form of air pollution: they're believed to have long-term (chronic) effects on people's health and they play a role in the formation of ozone and smog. VOCs are also released by tobacco smoke and wildfires. [10] Particulates : There are many different kinds of particulates, from black soot in diesel exhaust to dust and organic matter from the desert. Airborne liquid droplets from farm pollution also count as particulates. Particulates of different sizes are often referred to by the letters PM followed by a number, so PM 10 means soot particles of less than 10 microns (10 millionths of a meter or 10µm in diameter, roughly 10 times thinner than a thick human hair). The smaller ("finer") the particulates, the deeper they travel into our lungs and the more dangerous they are. PM 2.5 particulates are much more dangerous (they're less than 2.5 millionths of a meter or about 40 times thinner than a typical hair). In cities, most particulates come from traffic fumes. [11] Ozone : Also called trioxygen, this is a type of oxygen gas whose molecules are made from three oxygen atoms joined together (so it has the chemical formula O 3 ), instead of just the two atoms in conventional oxygen (O 2 ). In the stratosphere (upper atmosphere), a band of ozone ("the ozone layer") protects us by screening out harmful ultraviolet radiation (high-energy blue light) beaming down from the Sun. At ground level, it's a toxic pollutant that can damage health. It forms when sunlight strikes a cocktail of other pollution and is a key ingredient of smog (see box below). [12] Chlorofluorocarbons (CFCs) : Once thought to be harmless, these gases were widely used in refrigerators and aerosol cans until it was discovered that they damaged Earth's ozone layer. We discuss this in more detail down below. [13] Unburned hydrocarbons : Petroleum and other fuels are made of organic compounds based on chains of carbon and hydrogen atoms. When they burn properly, they're completely converted into harmless carbon dioxide and water ; when they burn incompletely, they can release carbon monoxide or float into the air in their unburned form, contributing to smog. Lead and heavy metals : Lead and other toxic "heavy metals" can be spread into the air either as toxic compounds or as aerosols (when solids or liquids are dispersed through gases and carried through the air by them) in such things as exhaust fumes and the fly ash (contaminated waste dust) from incinerator smokestacks.

Acid rain—a closer look.

Photo: Acid rain can turn lakes so acidic that fish no longer survive. Picture courtesy of U.S. Fish and Wildlife Service Division of Public Affairs. Why does that matter? Pure water is neither acidic nor alkaline but completely neutral (we say it has an acidity level or pH of 7.0). Ordinary rainwater is a little bit more acidic than this with about the same acidity as bananas (roughly pH 5.5), but if rain falls through sulfur dioxide pollution it can turn much more acidic (with a pH of 4.5 or lower, which is the same acidity as orange or lemon juice). When acid rain accumulates in lakes or rivers, it gradually turns the entire water more acidic. That's a real problem because fish thrive only in water that is neutral or slightly acidic (typically with a pH of 6.5–7.0). Once the acidity drops below about pH 6.0, fish soon start to die—and if the pH drops to about 4.0 or less, all the fish will be killed. Acid rain has caused major problems in lakes throughout North America and Europe. It also causes the death of forests, reduces the fertility of soil, and damages buildings by eating away stonework (the marble on the US Capitol in Washington, DC has been eroded by acid-rain, for example). One of the biggest difficulties in tackling acid rain is that it can happen over very long distances. In one notable case, sulfur dioxide air pollution produced by power plants in the UK was blamed for causing acid rain that fell on Scandinavian countries such as Norway, producing widespread damage to forests and the deaths of thousands of fish in acidified lakes. The British government refused to acknowledge the problem and that was partly why the UK became known as the "dirty man of Europe" in the 1980s and 1990s. [18] Acid rain was a particular problem in the last 30–40 years of the 20th century. Thanks to the decline in coal-fired power plants, and the sulfur dioxide they spewed out, it's less of a problem for western countries today. But it's still a big issue in places like India, where coal remains a major source of energy. Global air pollution It's hard to imagine doing anything so dramatic and serious that it would damage our entire, enormous planet—but, remarkable though it may seem, we all do things like this everyday, contributing to problems such as global warming and the damage to the ozone layer (two separate issues that are often confused). Global warming Every time you ride in a car, turn on the lights, switch on your TV , take a shower, microwave a meal, or use energy that's come from burning a fossil fuel such as oil, coal, or natural gas, you're almost certainly adding to the problem of global warming and climate change: unless it's been produced in some environmentally friendly way, the energy you're using has most likely released carbon dioxide gas into the air. While it's not an obvious pollutant, carbon dioxide has gradually built up in the atmosphere, along with other chemicals known as greenhouse gases . Together, these gases act a bit like a blanket surrounding our planet that is slowly making the mean global temperature rise, causing the climate (the long-term pattern of our weather) to change, and producing a variety of different effects on the natural world, including rising sea levels.

Towards a pollution-free planet

Introduction

Pollution has significant impacts on human health , the environment, and even on how some of the Earth’s systems, such as the climate, are functioning. Pollution touches all parts of the planet. It is affecting our health through the food we eat, the water we drink and the air we breathe. Approximately 19 million premature deaths are estimated to occur annually as a result of the way we use natural resources to support global production and consumption and which impact the environment.

Pollution touches all parts of the planet. It is affecting our health through the food we eat, the water we drink and the air we breathe. Approximately 19 million premature deaths are estimated to occur annually as a result of the way we use natural resources and impact the environment to support global production and consumption.

The 2030 Agenda for Sustainable Development adopted by the United Nations in 2015 commits to “ensure that all human beings can enjoy prosperous and fulfilling lives and that economic, social and technological progress occurs in harmony with nature”. How does pollution fit in that picture?

What are the sources of pollution?

Pollution can take many forms, ranging from organic compounds and other chemical substances to different types of energy. Some types of pollution are easily noticed, such as certain forms of contaminated water, poor air quality, industrial waste, litter , light, heat and noise. Others are less visible, for example pesticides in food, mercury in fish, excess nutrients in the sea and lakes, endocrine-disrupting chemicals in drinking water, and other micro- pollutants in fresh and marine water. Some, such as those coming from abandoned industrial sites, armed conflict zones, nuclear power stations, pesticide stockpiles and waste landfills , form part of a longer-term legacy.

The sources and types of pollution are highly diverse, as are the solutions to deal with them. For example, hazardous chemicals in paints, cleaning compounds, dyes, electronic products, and many other household substances can become pollutants if not managed correctly. Ecosystem functions are put at risk as well. There are also many emerging and novel products, such as some therapeutic drugs and nanomaterials , for which data on potential pollution effects are sparse.

On the other hand, food waste globally has been estimated to be as high as one third of all food produced for human consumption – nearly 1.3 billion tons.

Figure 3: Major sources of today's pollution

Market demand on one side of the planet is often satisfied by labour, production and natural resources originating from halfway across the globe. Fossil fuels now account for 50 per cent of the global trade volume. Research finds that trade leads to a redistribution of environmental burden towards countries that extract and produce resources. As such, the environmental impacts and pollution generated by global consumption habits are disassociated from those most impacted locally. Trade patterns, policies and agreements can play a crucial role in internalizing some of the environmental and social costs of production in order to minimize pollution at a global scale .

Air pollution

One important source of air pollution is indoor air pollution produced by the use of solid fuels for cooking in the house. The other major source of air pollution is outdoor pollution resulting from the burning of fossil fuels . Wildfires, the burning of waste, and tobacco smoke, all also contribute to air pollution. It is estimated that nine out of ten people in the world are breathing air that is polluted beyond the World Health Organisation (WHO) acceptable standards.

Land and soil pollution

Land and soil pollution is largely due to agricultural practices, to improper irrigation, to solid waste management problems such as landfills , and to a range of industrial, military and extractive activities. Globally, estimates indicate that at least 1 million people are unintentionally poisoned every year by excessive exposure and inappropriate use of pesticides , with health effects on all.

The waste products of industrial processes or mining activities are another source of pollution as they may contain heavy metals , pharmaceuticals and microorganisms , which can be difficult to remove once they find their way into the environment. Former industrial or military sites that are no longer in use can also be the sources of pollutants if they are not decontaminated properly. While some high-income countries have programs and regulations to deal with soil pollution, many poorer nations lack such programs, and are at risk to form ‘pollution hotspots’.

Freshwater pollution

Rivers and lakes are heavily affected by pollution, especially by the excess nutrients that come from the use of fertilisers in agriculture, one of the most pervasive water quality issues on a global scale , interfering with many human water uses and causing major shifts of species in ecosystems and loss of biodiversity .

Over 80 per cent of the world's wastewater is released to the environment without treatment creating a pollution from pathogens as well as from chemicals such as heavy metals from mining and industrial waste. These lead to a loss of biodiversity and to water that is improper for human consumption.

Marine and coastal pollution

Oceans receive most of their pollutants from land through rivers in the form of nutrients , waste, heavy metals and plastic debris which fragment into pieces of less than 5 mm but do not biodegrade in the marine environment. The rest comes from the fishing, shipping, and energy industries. The impacts of ocean acidification, which are for a large part associated with the dissolution of carbon dioxide emissions, are most visible on marine species with calcareous skeletons, such as corals and plankton which form the base of many marine food webs.

What are the impacts of pollution?

The severity of a pollutant for human health and ecosystems is dependent on its chemical nature and intrinsic toxicity, quantities emitted, exposure concentrations and persistence. Highly hazardous chemicals, such as mercury , ammonium, ozone, and some organic compounds used in a range of industries have the potential to cause cancer , birth defects , induce genetic damage, cause miscarriage, injury or death from relatively small exposures , if released into the environment. The specific harm caused by different pollutants depends not only on the environment where it is emitted (air, water or soil) but also possibly on the mix of pollutants that are present and the actual level of exposure. For example, about 125 million people in the world are exposed to asbestos at the workplace with over 100,000 still dying annually from such exposure.

Pollution poses a direct threat to respecting, protecting and promoting human rights and gender equality, international human rights obligations related to health, life, food and water. Due to their general health status, potential higher exposures and reduced resilience to social, environmental and economic risks, pollution can have a particularly disproportionate and negative effect on the poor, the disadvantaged, the marginalized, indigenous peoples, the disabled and the vulnerable . For instance, children poisoned by mercury and lead develop problems‹in their nervous and digestive systems and kidney damage. In addition, many toxic dumpsites are located in poor areas, leading to environmental injustice.

Pollution has also significant economic costs from the point of view of health, productivity losses, health-care costs and ecosystem damages. If consumption and production patterns continue as they are, the linear economic model of “take-make-dispose” will seriously burden an already polluted planet, affecting current and future generations.

For instance, in 2013 it was estimated that the cost of air pollution was more than 5 000 billion USD, which is more than the annual budget of the United States. These substantial costs, are expected to rise over time, not only because of the direct effect of pollution on health, but also because of the impact of weakened livelihoods, as well as the longer-term impact on ecosystem services , that in turn affect local communities , societies and economies. With a better understanding of the economic costs of pollution, the human costs of pollution are critical information for decision-making and to support more effective policies.

If consumption and production patterns continue as they are, the linear economic model of “take-make-dispose” will seriously burden an already- polluted planet, affecting current and future generations.

What is currently being done to address pollution?

Pollution is not a new phenomenon; it is largely controllable and often avoidable, but still considerably neglected. Thanks to better knowledge, alternative consumption and production models, as well as innovative technological solutions, many countries, cities, and businesses can now successfully tackling serious pollution issues.

Today, a majority of UN Member States recognize environmental rights. The first Principles of both the 1972 Stockholm and 1992 Rio Declarations focused on the human right to a safe and clean environment. The Stockholm Declaration describes “the fundamental right to freedom, equality and adequate conditions of life, in an environment of a quality that permits a life of dignity and well-being...”, while the Rio Declaration states that humans “are entitled to a healthy and productive life in harmony with nature”. These declarations have, together with other principles, informed many national constitutions over the past three decades.

At the same time, voluntary environmental initiatives have supported more formal environmental agreements, resulting in progress in some areas. But even more robust governance frameworks are required to bring us closer to a pollution-free planet. In particular, the 17 Sustainable Development Goals of the United Nations 1 provide an opportunity to accelerate the implementation of targeted and time-bound actions on pollution, which have been hitherto limited and inadequate.

With regards to chemicals and waste, legally binding approaches at the global level are essential to addressing the most critical and complex pollution challenges.

Existing multilateral environmental agreements already enable actions. This was notably in relation to the ban and substitution of ozone-depleting substances achieved in 2015, to the elimination of persistent organic pollutants and of most hazardous industrial chemicals and pesticides in international trade, as well as to hazardous and household waste and in particular to mercury with the entry into force of the Minamata Convention in 2017. Several of the multilateral environmental agreements were ratified worldwide or nearly worldwide.

The Convention on Biological Diversity’s Aichi Biodiversity Targets 2 also calls for a decrease in pollution and demands specific actions on excess nutrients . Today, a majority of UN Member States recognizes environmental rights. As of 2015, over 100 countries guaranteed their citizens a right to a healthy environment, with the majority of countries building this into their national constitutions. Although no international agreement explicitly recognizes the right to a healthy environment, national constitutions have played a vital role at the forefront of human rights and environmental protection . The majority of constitutional environmental rights include substantive, procedural, and emerging rights, such as the right to health and food, while others refer to policy-based, reciprocal-duty, and miscellaneous provisions.

Encouragingly, more governments, industries and citizens are moving towards sustainable materials management, greater resource efficiency, less environmentally damaging chemistry, clean technologies, and circular economies, as part of a more comprehensive transformation towards a sustainable economy. Trade can lead to greater environmental burdens in countries that extract and produce resources, as such activities generate waste and emissions. But trade can also provide solutions in terms of improved environmental goods and services . However, the capacity to adequately tackle pollution varies hugely across regions, social groups and genders.

At the same time, responses by governments, business and citizens to pollution remain sometimes limited in scope and scale and to date, there are no legally binding agreements that systematically address pollution in all its forms. If global and regional environmental agreements provide a partial framework, there are many gaps. For example, some agreements are only target-based, some are time-bound, while others cover also compliance-related actions, monitoring and reporting. For example, voluntary initiatives and global alliances – on topics such as fuel efficiency improvements, cleaner air and lead in paint – have addressed some of the more urgent issues, yet much more remains to be done to control and prevent pollution.

What are the benefits of addressing pollution?

It is obvious from many case studies that tackling pollution has already brought multiple benefits even if current responses may still be limited and inadequate. Projections indicate that further actions have the potential to enhance both health, well-being, and the economy. Two success stories show what can be achieved: the healing of the ozone layer and the phasing out of lead in fuel.

  • The Montreal Protocol ensured that to date more than 99 per cent of the historic baseline levels of consumption and production of harmful ozone-depleting substances have been phased out and its Multilateral Fund provided roughly $3.7 billion to more than 140 countries to phase out ozone-depleting substances, with lasting influence on innovation, technology transfer, strengthening of environmental governance , and training of customs officers and technicians. As a result, the ozone layer is healing and is expected to be restored by the middle of the century. Consequently, up to two million cases of skin cancer may be prevented each year by 2030, decreases in agricultural and fisheries yields will be avoided and up to 0.5°C of global warming will be avoided by the end of the century as ozone-depleting susbstances were also responsible of about 20% of the greenhouse gas emissions.
  • For lead additives in fuels the phase out is now almost complete, with only three countries still using some lead in fuel, all of which are set to stop by the end of 2017. Governments, the oil and auto industries, and civil society have worked together to support a global shift to unleaded fuels. This massive shift prevents an estimated 1.2 million premature deaths every year, and it also has a positive impact on children’s intellectual ability as lead is known to affect children’s IQ (United Nations Environment Programme 2016a).

Traditional pollution control that relies on “end-of-pipe” technologies has been shown to reduce polluting substances, such as in the case of sulphur dioxide (SO 2 ) and nitrogen oxides (NO x ) emissions from heating and energy production units. However, these technologies also require materials and energy upfront to produce the equipment, and as a consequence, may increase environmental impacts.

What actions can be taken to make the world truly pollution-free?

Solutions to help remove pollutants and detoxify our environment exist around the world. These need to be expanded, shared, and scaled up in order to avoid risking further exposure of humans and ecosystems to current and future pollution as well as increasing the costs of clean up. Improved risk assessment of new pollution sources is also urgently needed. Transitioning to a pollution-free world can drive innovation and social equity throughout the economy, by seeing pollution prevention and regulation compliance as an opportunity to clean up everyone’s environment, create new jobs, improve economic productivity and protect the rights of this and future generations.

Resource efficiency over the whole production -consumption system in particular can generate products which are identical or have the same functionality as when using traditional technologies and processes, while also reducing critical emissions and mitigating resource requirements and environmental impacts in the upstream processes.

Moving to less-polluting and nature-based technologies also offers economic and employment opportunities. Renewable energy provided jobs for 9.8 million people worldwide in 2016, compared to 5.7 million in 2012. Waste recycling and reuse also offers the chance to convert waste into economic opportunities, including jobs. As secondary materials replace virgin materials (for example phosphate from fertilizer nutrient recovery), they reduce the resource and environmental footprint of growth, but they can also have income and job impacts on primary exporting countries. Thus, careful and inclusive transition planning is required for those affected by these transformations. It is estimated that the global market for environmental goods and services reached $866 billion in 2011, and is expected to rise to $1.9 trillion by 2020.

However, challenges and gaps still limit the effectiveness of current actions. The key gaps are:

  • implementation,
  • infrastructure,
  • limited financial and industry leadership,
  • pricing and fiscal, and
  • behavioural.

Implementation gaps are in particular due to a lack of resources; inadequate administrative, financial, institutional and technical capacity, and the absence of inter-ministerial coordination and political will. Absence of inter-ministerial coordination being a key reason why action does not happen.

There is also insufficient recognition by different actors that producer and consumer choices have pollution consequences. Such choices – even in the presence of pollution policies and regulations – can be made out of habit, a feeling that one person or firm cannot make a difference.

This report “Towards a pollution-free planet” is about encouraging a synergetic mix of actions and a whole-system, multi-beneficial policymaking approach that builds directly on existing internationally agreed environmental goals, including those relating to climate change , disaster and risk reduction and the 2030 Agenda for Sustainable Development , with its numerous pollution-reducing targets. As already underlined, existing international environmental agreements and the 2030 Agenda for Sustainable Development present significant opportunities to accelerate actions to tackle pollution and improve the well-being of humans and ecosystems . The international framework for the Sustainable Development Goals encourages synergies between the Goal 3 and its associated target to “substantially reduce the number of deaths and illnesses from hazardous chemicals and air, water and soil pollution and contamination”, and others such as the targets for climate change, air quality, nutrient pollution and marine debris. These links are detailed in the appendices of the report.

A pollution-free planet is by far and away the best insurance for the survival and well-being of current and future generations of humans and ecosystems . To advance this goal, this report has the following five overarching messages

  • A global compact on pollution would make prevention a priority for all. It would also encourage policymakers to integrate prevention into national and local planning, development processes, poverty reduction strategies and national accounts;
  • Environmental governance needs to be strengthened at all levels – with targeted action on “hard-hitting” pollutants through risk assessments and enhanced implementation of environmental legislation (including multilateral environmental agreements) and other measures;
  • Sustainable consumption and production should be promoted through improved resource efficiency and lifestyle changes, waste reduction and management being prioritized;
  • Investment in cleaner production and consumption will help to counter pollution , alongside increased funding for pollution monitoring , infrastructure, management and control;
  • Multi- stakeholder partnerships and collaboration are vital for the innovation, knowledge-sharing and transdisciplinary research needed to develop technological and ecosystem -based solutions.

To reach these objectives, this report suggests a dual track of actions as framework for actions on pollution that UN Member States and other stakeholders may wish to consider to curb pollution around the world. This dual framework consists in the following combination:

  • Targeted interventions , based on risk assessments and scientific evidence of impacts, to address “hard-hitting” pollutants as well as areas of pollution (air, water, marine and coastal, land/soil), including cross-cutting categories (chemicals, waste);
  • System-wide transformations to shift the economy toward greater resource efficiency and equity , circularity and sustainable consumption and production , and improved ecosystem resilience to support cleaner and more sustainable development .

This dual track of actions is guided and underpinned by the two other elements of the framework:

  • The five principles drawn from the Rio Declaration and the 2030 Agenda for Sustainable Development : universality, sustainability , integration, precaution and inclusiveness.
  • Enablers, or broader supporting actions, to shift incentives, correct market and policy failures and address some of the gaps and issues that make pollution so pervasive and persistent .

The report then present in more details the actions that should be undertaken to tackle the challenges in the various areas and lead to a “pollution-free planet”.

Short Essay On Environmental Pollution

Environmental pollution refers to the introduction of harmful substances or products into the environment. It is a major problem in today’s world and has a profound impact on both the natural world and human lives.

The sources of environmental pollution are numerous and varied, including industrial activities, transportation, and household waste. One of the most significant contributors to environmental pollution is the burning of fossil fuels, which releases toxic chemicals and greenhouse gases into the atmosphere. This not only contributes to air pollution, but it also has a significant impact on climate change, causing rising temperatures, extreme weather events, and melting of polar ice caps.

Another major source of environmental pollution is the disposal of hazardous waste. This includes chemicals, batteries, and electronic waste, which contain toxic substances that can contaminate soil and groundwater, leading to serious health problems for both humans and wildlife.

The effects of environmental pollution are far-reaching and often devastating. It can cause serious health problems for humans, including respiratory problems, heart disease, and cancer. Additionally, environmental pollution can have a significant impact on wildlife, causing a decline in biodiversity and threatening species with extinction.

To address environmental pollution, it is essential that we take a multi-faceted approach, addressing both the causes and consequences of pollution. This may involve reducing the use of fossil fuels and implementing clean energy technologies, as well as improving waste management and increasing public awareness about the impact of pollution.

In conclusion, environmental pollution is a serious problem that has a profound impact on both the natural world and human lives. To address this problem, it is essential that we take a comprehensive approach, addressing the causes and consequences of pollution and working to reduce its impact on the environment. By taking action now, we can protect the future of our planet and ensure a healthy and sustainable future for generations to come.

Long Essay On Environmental Pollution

Environmental pollution is one of the biggest threats to our planet today. It affects both the environment and human health, and it’s becoming more and more pervasive in our daily lives. In this essay, we’ll explore what environmental pollution is, how it affects us, and what the most effective solutions are to reduce its impact on people and the planet.

Introduction

There are many different types of environmental pollution. Some of the most common include air pollution, water pollution, and soil contamination. Each type of pollution has different causes and effects. Air pollution is typically caused by emissions from factories and automobiles. These emissions can contain harmful chemicals that can cause respiratory problems, heart disease, and cancer. Water pollution is often caused by sewage or agricultural runoff. This pollution can contaminate drinking water supplies and make people sick. Soil contamination can be caused by hazardous waste disposal or mining operations. This contamination can make crops unsafe to eat and cause health problems in people who come into contact with it.

Causes of Environmental Pollution

There are many causes of environmental pollution. The most common cause is the release of harmful chemicals into the environment. These chemicals can come from factories, power plants, cars, and other sources. They can pollute the air, water, and soil. They can also cause health problems for people and animals.

Other causes of environmental pollution include sewage, agricultural runoff, and mining. Sewage can contain harmful bacteria and viruses that can pollute water supplies. Agricultural runoff can contain pesticides and fertilizers that can pollute rivers and lakes. Mining can release harmful metals and minerals into the environment.

Types of Pollutants and Their Impact on the Environment

There are many different types of pollutants that can have an adverse impact on the environment. Some of the most common pollutants include:

‱ Air pollution – This is one of the most visible forms of pollution and can cause a range of health problems, including respiratory illnesses.

‱ Water pollution – This can lead to contamination of drinking water supplies and also harm marine life.

‱ Soil pollution – This can contaminate crops and lead to soil erosion.

‱ Light pollution – This can disrupt the natural circadian rhythms of animals and cause light-sensitive species to suffer.

All of these pollutants can have a serious impact on the environment, both in terms of the immediate damage they cause and also the long-term effects. It is therefore important to be aware of the different types of pollutants and their potential impacts.

Effects Of Environmental Pollution

There are many effects of environmental pollution. Some of the most common include air pollution, water pollution, and soil contamination.

Air pollution is one of the most harmful forms of environmental pollution. It is a major contributor to respiratory problems, heart disease, and cancer. Air pollution is also a leading cause of climate change.

Water pollution is another major problem caused by environmental pollution. It can contaminate drinking water supplies, damage aquatic ecosystems, and make recreation in waterways unsafe.

Soil contamination can occur when pollutants such as chemicals or oil spills enter the ground. This can make crops difficult to grow and can contaminate food supplies. Soil contamination can also cause health problems if people come into contact with contaminated soil or eat contaminated food.

Prevention and Control Measures

There are a number of things that individuals can do to help prevent and reduce environmental pollution. One of the most important things is to educate yourself and others about the issue and its causes. This can help raise awareness and create a demand for change. Another key prevention measure is to support businesses and industries that are working to reduce their pollution output. This includes voting with your wallet by patronizing companies that have green policies in place, and investing in cleaner energy sources. Finally, you can take action in your own life to reduce your impact on the environment. This includes conserving energy, recycling, driving less, and composting.

In conclusion, environmental pollution has become a major global concern and it is important for us to take proactive steps to reduce the amount of pollutants that are entering our environment. We can start by reducing our consumption of single-use products, switching to renewable energy sources such as solar or wind power, and engaging in conscientious recycling habits. By taking these actions we can help protect our planet from further harm caused by environmental pollution.

What is Environmental Pollution?

The phenomenon of undesirable changes in the surroundings that are harmful to animals and plants, and leads to environmental degradation is known as environmental pollution. These changes can occur because of the solid, liquid or gaseous pollutants. For example, DDT, plastic, and heavy materials take more time to degrade and are known as notable pollutants. For the determination of risk assessment of public health, concentration of pollutants is measured.

Essay on Environmental Pollution – 100 Words 

The presence of contaminants in the environment is referred to as pollution. Gases like Carbon Dioxide (CO2) and Carbon Monoxide (CO), among others; solid pollutants like plastic, sewage, etc.; and chemicals like fertilisers, as well as those produced as byproducts in manufacturing, transportation, etc., are a few examples of polluting substances.

The immediate result of pollution is that it makes the world’s natural resources useless or toxic to use, as well as leads to the extinction of species and ecological imbalance. To stop more harm from occurring to the earth and its inhabitants due to environmental pollution, it is imperative to take proactive precautions.

Essay on Environmental Pollution – 250 Words 

When undesired elements, or pollutants, are present in the environment, it is said to be polluted. The environment is severely harmed by pollution, which poses a direct threat to it. Although the world has begun to understand the importance of addressing pollution if the planet and its biodiversity are to be conserved there is still a long way to go.

Everything that makes up the environment, including the air, water bodies, flora, and wildlife, is impacted by pollution in one way or another. There are four main types of pollution – Air Pollution, Water Pollution, Noise Pollution and Soil or Land Pollution . Additionally, pollution contributes to global issues including acid rain, global warming, and greenhouse gas consequences. A rise in the planet’s average surface temperature is referred to as global warming, and it causes starvation, floods, and droughts.

Environmental pollution has a wide-ranging impact. In addition to the current effects of pollution, a lack of effective pollution prevention measures also imperils the future of various species. The pollution is causing harm at a far faster rate than it can be healed. Reversing the environmental harm we have caused could take generations, and even then, it won’t be simple. It will require tight discipline and commitment to stop pollution.

The best ways feasible are being used by various nations to respond to these catastrophes. More efforts are being launched to raise public awareness about the dangers of pollution and the importance of preserving our ecosystem. Greener lifestyles are gaining popularity; examples include using wind and solar energy, new climate-friendly cars, and energy-efficient lighting.

Essay on Environmental Pollution – 500 Words 

Pollution is the term used to describe the entry of pollutants into the environment. Noise, water, and air pollution are only a few of the several types of pollution. There is a direct relationship between the rise of pollution levels and illnesses among people. Therefore, it is important for everyone to be knowledgeable about pollution, its impacts, and effective ways to eliminate it. Our environment needs a balanced combination of all components, just like our body requires a balanced diet. The environment is polluted by any substance that is present above that limit for example rise in the levels of nitrogen oxides and carbon dioxide in the atmosphere causes harm to human health due to poor air quality. 

All forms of pollution, whether in the air, water, soil, or noise, have a negative impact on living things. Deadly diseases that are brought on by the contamination of soil, water, air, or sound affect organisms.

Among the most common disorders brought on by air pollution are acute lower respiratory infections in children, ischemic heart disease, stroke, lung cancer, chronic obstructive pulmonary disease (COPD), and lung cancer. Air pollution is a major contributor to a number of ailments in India, including strokes, bronchitis, heart attacks, lung diseases, cancer, and early mortality from heart disorders. The most pressing issue in the world now is global warming, which is caused by air pollution.

Around the world, poor drinking water quality is the reason behind 50% of child deaths and 80% of illnesses, including more than 50 different diseases. Water pollution causes diarrhoea, skin diseases, malnutrition, and even cancer, as well as other issues that are related to it.

 Every day, noise pollution has an effect on millions of people. The most frequent result of this is noise-induced hearing loss (NIHL). Loud noises have the potential to cause stress, high blood pressure, heart disease, and sleep difficulties. Children in particular are prone to these health issues across the board in terms of age groups. Noise pollution is extremely harmful, and it’s especially deadlier for people with heart issues. 

Use of the 3Rs, or reduce, reuse, and recycle, is the first step in reducing pollution. People should use air conditioners less since they generate noxious gases, such as ozone-depleting chlorofluorocarbons, which will minimise air pollution.

Reducing the number of vehicles on the road will also help to clean up the planet’s air. The more often cars are used, the more dangerous chemicals like sulphur dioxide, nitrogen oxides, carbon monoxide, and hydrocarbons that contribute to major air pollution are released into the atmosphere.

Increasing public awareness is a further means of reducing pollution on Earth. Through programmes like the “Go Green” campaign, which urges people to plant more trees and use recyclable materials in their daily lives, awareness can be raised about the significance of eliminating pollution on Earth. The “Earth Hour” is another globally recognised event that calls for everyone to turn off all lights for one hour in order to raise awareness of the significance of reducing electricity usage in order to minimise pollution on Earth.

The government’s obligation to maintain national laws is one way to reduce pollution on Earth. Offenders should be subject to harsh penalties, such as increased fines and longer prison terms, which will force them to reconsider their influence on the environment and serve as a message to those who are not currently involved but who might be in the future.

But, due to increasing industrialization and concentration of poisonous gases in the environment the air is getting more and more toxic day by day. Also, these gases are the cause of many respiratory and other diseases . Moreover, the rapidly increasing human activities like the burning of fossil fuels, deforestation is the major cause of air pollution.

Essay on Air Pollution

How Air Gets Polluted?

The fossil fuel , firewood, and other things that we burn produce oxides of carbons which got released into the atmosphere. Earlier there happens to be a large number of trees which can easily filter the air we breathe in. But with the increase in demand for land, the people started cutting down of trees which caused deforestation. That ultimately reduced the filtering capacity of the tree.

Moreover, during the last few decades, the numbers of fossil fuel burning vehicle increased rapidly which increased the number of pollutants in the air .

Causes Of Air Pollution

Its causes include burning of fossil fuel and firewood, smoke released from factories , volcanic eruptions, forest fires, bombardment, asteroids, CFCs (Chlorofluorocarbons), carbon oxides and many more.

Besides, there are some other air pollutants like industrial waste, agricultural waste, power plants, thermal nuclear plants, etc.

Greenhouse Effect

The greenhouse effect is also the cause of air pollution because air pollution produces the gases that greenhouse involves. Besides, it increases the temperature of earth surface so much that the polar caps are melting and most of the UV rays are easily penetrating the surface of the earth.

Moreover, it increases the rate of aging of lungs, decreases lungs function, damage cells in the respiratory system.

Ways To Reduce Air Pollution

Although the level of air pollution has reached a critical point. But, there are still ways by which we can reduce the number of air pollutants from the air.

Reforestation- The quality of air can be improved by planting more and more trees as they clean and filter the air.

Policy for industries- Strict policy for industries related to the filter of gases should be introduced in the countries. So, we can minimize the toxins released from factories.

Use of eco-friendly fuel-  We have to adopt the usage of Eco-friendly fuels such as LPG (Liquefied Petroleum Gas), CNG (Compressed Natural Gas), bio-gas, and other eco-friendly fuels. So, we can reduce the amount of harmful toxic gases.

To sum it up, we can say that the air we breathe is getting more and more polluted day by day. The biggest contribution to the increase in air pollution is of fossil fuels which produce nitric and sulphuric oxides. But, humans have taken this problem seriously and are devotedly working to eradicate the problem that they have created.

Above all, many initiatives like plant trees, use of eco-friendly fuel are promoted worldwide.

Introduction Of Pollution Essay

Pollution is the introduction oaf contaminant into a natural environment, usually by humans. While most people think of pollution as chemical waste dumped into rivers, or factories spewing toxins into the air, it can also include light pollution or sound pollution. These are example of pollutions such as air pollution, water pollution and land pollution. Firstly, the air pollution is the accumulation in the atmosphere of substances that, in sufficient concentrations, endanger human health or produce other measured effects on living matter and other materials.

Essay Example on Term Paper On Pollution

Among the major sources of pollution are power and heat generation, the burning of solid wastes, industrial processes, and, especially, transportation. The six major types Of pollutants are carbon monoxide, hydrocarbons, nitrogen oxides, particulates, sulfur dioxide, and photochemical oxidants. These are examples of air pollution; * Tobacco Smoke Tobacco smoke is one of the major forms of pollution in buildings. It is not only the smoker who is infected, but everyone who inhales the polluted air.

There is a very strong connection between smoking and lung cancer. Bronchitis is common among smokers and unborn babies of mothers who smoke also suffer from the harmful effects of smoking. * Exhaust Gases of Vehicles Pollution from exhaust gases of vehicles is responsible for 60% of all air pollution and in cities up to 80%. There is a large variety of harmful chemicals present in these gases, with lead being one Of the most dangerous. Combustion of Coal The combustion of coal without special precautions can have serious consequences.

If winds do not blow away the poisonous gases, they can have fatal effects and may lead to death. Acid rain Acid rain is the term for pollution caused when sulfur and nitrogen dioxides combine with atmospheric moisture to produce highly acidic rain, snow, hail, or fog. The acid eats into the stone, brick and metal articles and pollutes water sources. Coal in South Africa is rich in sulfur and the power stations in the Mulligan Province could be responsible for acid rain over other areas of our country.

Moreover, another example of pollution is water pollution. Water pollution is the introduction into fresh or ocean waters of chemical, physical, or illogical material that degrades the quality of the water and affects the organisms living in it. This process ranges from simple addition of dissolved or suspended solids to discharge of the most insidious and persistent toxic pollutants (such as pesticides, heavy metals, and no degradable, bio accumulative, chemical compounds).

These are examples Of water pollution * Industrial affluent Water is discharged from after having been used in production processes. This waste water may contain acids, alkalis, salts, poisons, oils and in some cases harmful bacteria. K Mining and Agricultural Wastes Mines, especially gold and coal mines, are responsible for large quantities of acid water. Agricultural pesticides, fertilizers and herbicides may wash into rivers and stagnant water bodies. Sewage Disposal and Domestic Wastes Sewage as well as domestic and farm wastes were often allowed to pollute rivers and dams. Lastly is the land pollution. Land pollution is the degradation of the Earth’s land surface through misuse of the soil by poor agricultural practices, mineral exploitation, industrial waste dumping and indiscriminate disposal of urban wastes. It includes visible waste and litter as well as pollution of the soil itself.

Examples of Land Pollution; * Soil Pollution Soil pollution is mainly due to chemicals in herbicides (weed killers) and pesticides (poisons which kill insects and other invertebrate pests). Litter is waste material dumped in public places such as streets, parks, picnic areas, at bus stops and near shops. * Waste Disposal The accumulation Of Waste threatens the health Of people in residential areas. Waste decays, encourages household pests and turns urban areas into unsightly, dirty and unhealthy places to live in.

The 25 Photos That Defined the Modern Age

A group of experts met to discuss the images that have best captured — and changed — the world since 1955.

Supported by

By M.H. Miller ,  Brendan Embser ,  Emmanuel Iduma and Lucy McKeon

  • Published June 3, 2024 Updated June 4, 2024

This story contains graphic images of violence and death.

Let’s get this out of the way first: Of the dozens of photographers not represented here that a reasonable person might expect to have been included, the most conspicuous absentees include Berenice Abbott, Ansel Adams, Robert Adams, Richard Avedon, Dawoud Bey, Henri Cartier-Bresson, Imogen Cunningham, Roy DeCarava, William Eggleston, Walker Evans, Robert Mapplethorpe, Helmut Newton and Irving Penn. Putting together a list of the 25 most significant photographs since 1955 — both fine art photos and reportage — proved a difficult task for the panelists (even the chosen time frame was controversial). They were: the Canadian conceptual photographer Stan Douglas , 63; the Vietnamese American photographer An-My LĂȘ , 64; the acting chief curator of Photography at the Museum of Modern Art, Roxana Marcoci, 66; the American documentary photographer Susan Meiselas , 75; the American photographer Shikeith , 35; and Nadia Vellam, 51, T’s photo and video director. Each participant (including myself, the moderator, 36) submitted up to seven possible nominees for the list. We gathered at The New York Times Building on a morning last February (with Shikeith joining on video from a shoot in Los Angeles) to begin our deliberations.

We chose judges from the realms of both fine art and reportage because, increasingly, the line between the two has collapsed. The modern age has been defined by photographs — images that began their lives in newspapers or magazines are repurposed as art; art has become a vehicle for information. Therefore, it was important to us and our jurors that we not draw boundaries between what was created as journalism and what was created as art. What was important was that the photographs we chose changed, in some way, how we see the world.

Six people sit around a circular table. On the wall, a t.v. showing an image of that room.

The conversation naturally turned into a series of questions. Like how important was it for a photograph to have expanded the possibilities of the medium? And how much did it matter who took a photo and what their intentions were? The list that emerged is less concerned with a historical chronology or an accepted canon than it is with a set of themes that have been linked indelibly to the photographic medium since its inception: labor and activism; war; the self and the family. Intriguingly, beyond an image by Wolfgang Tillmans from the ’90s, fashion photography is largely absent. So, too, are many world historical events that have been captured in landmark photographs, including the assassination of JFK, the fall of the Berlin Wall and anything from the pandemic lockdown or the presidency of Donald Trump. There were just too many other photographs to consider.

The process of producing the final list was clearly not scientific. It was more of a debate among a certain group of people on a certain day and is best considered that way. At the end of nearly four hours, jittery from caffeine, the group stood before a pile of crumpled masterworks on the floor as we assembled our chosen 25 images on a conference table. Many of our questions weren’t resolved (indeed, are unresolvable), but the results — which aren’t ranked but rather presented in the order in which we discussed them — are nothing if not surprising. — M.H. Miller

The conversation has been edited and condensed.

M.H. Miller: I thought we should start by talking about the time frame we settled on, starting in 1955.

Stan Douglas: It’s an agenda.

Miller: A little bit. It certainly shows an American bias, so I apologize to our Canadian representative — 1955 is really the beginning of the American civil rights movement, an era from which a number of us nominated photographs, and photography was so important in just making people aware of what was going on in the country. An-My, you chose Robert Frank’s picture of a streetcar in New Orleans, taken that year.

1. Robert Frank, “Trolley — New Orleans,” 1955

Robert Frank used “Trolley — New Orleans” as the original cover of his influential photo book “The Americans,” first published in the United States in 1959. Frank, a Swiss Ă©migrĂ©, spent two years traveling the States and capturing what he saw. In this photograph, two Black passengers sit at the rear of a New Orleans streetcar while four white passengers sit at the front; all look out from a row of windows, the mullions between them emphasizing their strict separation. At the time of its publication, “The Americans” was considered by several critics to be a pessimistic, angry portrait of the country. (The magazine Popular Photography famously called it a “warped” and “wart-covered” depiction “by a joyless man.”) Many more viewers and artists, however, found inspiration in the direct, unromantic style pioneered by Frank, whose outsider status likely let him view America’s contradictions from a clarifying distance. He had “sucked a sad poem out of America onto film,” as Jack Kerouac wrote in an introduction to the book. This image, shot in the months before the Montgomery bus boycotts made segregation a national debate, showed America to itself, as if for the first time. The faces in the photographs, Kerouac wrote, don’t “editorialize or criticize, or say anything but ‘this is the way we are in real life.’” — Emmanuel Iduma

An-My LĂȘ: I tried to look for things that spoke to me, but also spoke to a generation.

Douglas: If I had to choose a civil rights image, I wouldn’t choose this one. Great photograph. But something happening on the street would be more appropriate, I think, like the dog attacking protesters , or the photo with the firemen .

Roxana Marcoci: But this was the cover of “The Americans,” and it does happen in the street, actually. I think that what you’re saying is, it’s not a photojournalistic image.

Douglas: The most important thing to me is: does a photograph reveal a new reality, or reveal something that’s been hidden previously? I think that’s a key criterion for making it significant. What impact on the world can that image have? A European might not have recognized that this was happening in the U.S. Maybe a lot of Americans in the North didn’t realize this was happening in the U.S. And I love this photograph, so I’m very happy to keep it.

2. David Jackson, Mamie Till and Gene Mobley Standing Before the Body of Emmett Till at a Chicago Funeral Home, 1955

Mamie Till fixes her eyes on her dead son, as her fiancĂ©, Gene Mobley, holding her, stares at the viewer. Emmett Till , 14, is laid out on a cot in a Chicago funeral home, his face disfigured and bloated. His mother allowed the photojournalist David Jackson to take this picture in September 1955, a few days after two white men had abducted and murdered Till while he was visiting relatives in Mississippi. Quickly acquitted by an all-white jury, the men would go on to sell their confession to Look magazine for $4,000. When this photo was published, first in Jet magazine and then in The Chicago Defender and other Black newspapers, it incited an unprecedented level of outrage in America over racial violence; Jet had to reprint the Sept. 15, 1955, issue in which it appeared because of high demand. For the same reason Mamie Till let this picture be taken, she chose to keep her son’s coffin open during the funeral. “The murder of my son has shown me that what happens to any of us, anywhere in the world, had better be the business of us all,” she said. An estimated 100,000 people came to view his body. Jackson’s photograph was a call to action for many, including Rosa Parks, who said she thought of Till when she refused to give up her seat on a Montgomery bus later that same year. — E.I.

Miller: I feel like you can’t have this conversation, especially with the year we designated as the starting point, without talking about Emmett Till. There’s the devastating series of photographs of Till’s funeral. But there’s also the one from the trial — when Till’s great-uncle is identifying the men who murdered his nephew. The judge didn’t allow that photographer, Ernest C. Withers, to shoot in the courtroom. So it’s a miracle that the picture exists, and that it’s composed as well as it is when it had to be taken in secret. And it’s a moment where you saw a larger shift taking place. Up to that point in the South, a Black witness identifying white defendants in court was unheard-of.

Marcoci: The picture [of his body] was also about the power of the witness, right?

Susan Meiselas: Oh, for sure. Mamie Till and her insistence on an open coffin: how brave an act that was. And it ran in Jet and moved around the world.

Douglas: The issue for me with the trial picture is that it needs a paragraph to explain why we’re looking at it.

Marcoci: The courtroom was a travesty. They went free. But this, Mamie Till with her son, created a generation of Black activists.

Shikeith: I grew up in a predominantly Black neighborhood in Philadelphia, and when we were learning about Black history in the fourth or fifth grade, that picture was brazenly shared with students. It was probably the first time I learned how powerful a photograph can be in having real material change in the world. It’s an image that I’ve lived with my [whole] life, and that’s impacted how I viewed the world and racism and its violence. It scares me. But, you know, it’s the truth. The truth can be very scary for a lot of us.

Miller: Shikeith, you also selected this Gordon Parks photograph, which is one of two color images the group nominated from the 1950s and ’60s — and the second was taken from outer space.

3. Gordon Parks, “Department Store, Mobile, Alabama,” 1956

In 1956, Life magazine sent Gordon Parks to document the effects of Jim Crow segregation laws in the American South through the experiences of one extended family in Mobile, Ala. Parks was one of the few Black photojournalists to work for an establishment magazine at the time, and was known especially for his fashion photography, as is easily apparent from this image. For Life, he photographed everyday scenes — a church choir singing or children drinking from water fountains — intentionally capturing signs reading “White Only” or “ Lots for Colored .” “Department Store, Mobile, Alabama” (1956) was shot for the Life story, which ran at 12 pages under the title “The Restraints: Open and Hidden” but, for unknown reasons, it didn’t make the final edit, and it wasn’t published until 2012, when a five-volume collection of Parks’s photographs was released. “Department Store” has since become a belated icon, one of the most memorable images in a career that also includes directing the 1971 film “Shaft.” Notable most of all for its vivid color, a startling contrast to the predominantly black-and-white imagery from the civil rights era, the portrait depicts Joanne Thornton Wilson, then age 27, dressed in an ice-blue, A-line cocktail dress, with her young niece, Shirley Anne Kirksey, standing beneath the red neon “Colored Entrance” sign in front of a department store. Wilson’s upright posture and outward gaze — peering in the opposite direction of the sign’s blue arrow — subtly signify defiance. But there’s an intimacy and vulnerability in the picture, too. In 2013, Wilson, who went on to become a high school teacher, told the art historian Maurice Berger that she regretted that the strap of her slip had visibly fallen. “Dressing well made me feel first class,” she said. “I wanted to set an example.” She had set an example, of course, which Parks had recorded with such clarity: Wilson also told Berger that she refused to take her niece through the “colored” entrance. — Brendan Embser

Shikeith: I think what’s beautiful about this image is that it’s brilliantly composed — it uses beauty to draw you into a poignant moment in history, becoming a record of the Jim Crow laws in the Southern U.S. I tried to pick photographs that had an influence on me, and that I thought my mother would recognize, to indicate their influence on people who might operate outside of art history conversations. It [can be used as] a tool for educating even the youngest of minds about what marginalized communities went through.

Marcoci: I think that’s a great point: the pedagogical nature of photographs. In this picture, there’s the elegance and grace of these two figures, and then the ugliness of that “Colored Entrance” sign. There’s such a tension between them.

Nadia Vellam: You don’t immediately realize the context because you’re so attracted to the two people in the image. It asks you to spend more time looking.

Douglas: It’s quite an exquisite picture. It’s basically an X, which draws your eye into the center, which then takes you to that woman’s gaze outside the frame. Inside the frame, there’s something quite sweet. But outside — both beyond that door and out in the world that’s made that door — there’s something quite ugly.

4. Alberto Korda, “Guerrillero Heroico (Che Guevara),” 1960

Alberto Korda, a favored photographer of Fidel Castro, captured this image of a 31-year-old Che Guevara by chance during a funeral in Havana in 1960 to honor the victims of a freighter explosion. Guevara, at the time the president of the National Bank of Cuba, happened to move into Korda’s line of sight while Castro was giving a speech. His expression is one of restrained anger; the Cuban government accused the United States of being responsible for the tragedy, which it denied. Five years later, Guevara resigned from Castro’s cabinet and joined revolutionary causes abroad, including in Congo and Bolivia, where he led guerrillas in a failed coup attempt. Korda’s photo wasn’t widely published until after Guevara’s execution by Bolivian soldiers in 1967, when posters, murals and eventually T-shirts emblazoned with Guevara’s face began to appear around the world. In the original portrait, he is flanked by another man and some palm fronds, but the reproductions are cropped to show just Guevara’s head. Korda’s image made Guevara into something more than a man, or even a famous revolutionary; he became a symbol for revolution itself. — E.I.

Miller: We have two pictures of Che Guevara to consider. Stan, you picked Che following his execution , and Susan, you picked the more famous portrait of him by Alberto Korda. It’s in every college dorm.

Marcoci: It’s in every tattoo parlor.

Douglas: They’re both propaganda images. One is the revolutionary looking to the future, which we’ve seen in everything from Soviet realist paintings to Obama posters. So, in many ways, a clichĂ©, even though it’s had this huge impact. The image of Che dead [which was taken by the Bolivian photographer Freddy Alborta] is both iconic in that it’s like [an Andrea] Mantegna [1431-1506] painting of the dead Christ [“ Lamentation Over the Dead Christ ,” circa 1480], but also as evidence, on the part of the people who killed him, that the guy is dead. It’s just such a weird photograph: the officer on the right who’s poking at Che’s body to prove he’s just a human. Just mortal. And it somehow seemed like the end of the export of revolution from Cuba, which very much shut down after Che’s death.

Meiselas: And then he’s resurrected as a tattoo.

5. Diane Arbus, “Boy With a Straw Hat Waiting to March in a Pro-War Parade, N.Y.C., 1967”

The boy in “Boy With a Straw Hat” doesn’t look like a typical Arbus subject. Wearing a prim collared shirt, bow-tie and boater hat, with one American flag at his side and another, much smaller one twisted into a bow on his lapel, the thin-lipped paradegoer seems like the paragon of anodyne conservatism. He’s nothing like the cross-dressers, carnival entertainers, nudists and others relegated to the margins of society that fascinated Arbus, whose work prompted one of the more protracted debates on the ethics of photography, as her images were so often said to skirt the lines of voyeurism and exploitation. Yet his steady gaze prompts a similar sense of unease in the viewer, as does the small pin on his jacket that reads Bomb Hanoi. “Boy With a Straw Hat” was the cover image of Artforum’s May 1971 issue, published two months before Arbus’s death by suicide at age 48. In 1972, when her posthumous MoMA retrospective drew record crowds, the art critic Hilton Kramer refuted the idea that she was merely capturing her subjects for the sake of spectacle; he argued that she collaborated with the people she photographed, and that that act of participation provided dignity — or at least authenticity — especially for those individuals who are shunned or otherwise invisible. Arbus herself once said that the “best thing is the difference. I get to keep what nobody needs.” — B.E.

Miller: A number of us nominated Diane Arbus photos.

Douglas: [I picked] the sitting room in Levittown [“ Xmas Tree in a Living Room in Levittown, L.I., 1962 ”], which is one of those suburbs created in the postwar period that people could buy [homes in] with their G.I. Bill money, in which Black people couldn’t live. It’s a case of there [being] something outside the image, which is very powerful: The construction of this new suburban reality, while Emmett Till’s being killed.

Marcoci: I chose the “Giant” [“ A Jewish Giant at Home With His Parents in the Bronx, N.Y., 1970 .”], because this was one of the first pictures where I was really thinking, “Who is that person? What would it be like to be him?”

Meiselas: One of the things that photographs do is make us emotional. Some of Arbus’s most memorable pictures are the ones that make you feel more than think.

Vellam: I’d vote for “Giant” just because it spawned so many people’s idea of portraiture: Katy Grannan, Deana Lawson, Larry Sultan. Like this idea of going into a place — in her case, middle-class suburbia — that you may not even have spent any time in otherwise. I feel like that became its own genre: There’s so much photography that has come out of her idea of going into people’s homes.

Marcoci: If I were to choose just one Arbus, I’d probably choose “Boy With a Straw Hat”: A portrait of an individual that’s this very interesting collective portrait of America, too. There’s this tension between the innocent face and then those buttons: “God Bless America” and “Bomb Hanoi.”

Shikeith: He’s sort of the archetype for the Proud Boys. You can see that smirk on his face.

Meiselas: There were pictures from the R.N.C. [Republican National Convention] four years ago that looked so much like this.

Miller: Stan and An-My both nominated a very different kind of photograph from the Vietnam War era: Malcolm Browne’s picture of ThĂ­ch QuáșŁng Đức’s self-immolation.

6. Malcolm Browne, the Self-Immolation of the Buddhist Monk ThĂ­ch QuáșŁng Đức in Saigon, 1963

The AP reporter Malcolm Browne was among the only photojournalists on the scene when the monk ThĂ­ch QuáșŁng Đức set himself on fire in 1963 in Saigon as an act of protest against the South Vietnamese government’s persecution of the Buddhist majority. As flames engulfed QuáșŁng Đức, hundreds of monks surrounded him, mourning while he burned. The photo, sent out as soon as possible on a commercial flight to reach the AP’s offices, was published on front pages internationally the following morning. When President John F. Kennedy saw it, he reportedly exclaimed, “Jesus Christ!” and then ordered a review of his administration’s Vietnam policy. (He would later say, “No news picture in history has generated so much emotion around the world as that one.”) Browne won the Pulitzer Prize in 1964 for the photograph, which also contributed to the collapse of support for the South Vietnamese president NgĂŽ ĐÏnh Diệm, who was assassinated in a coup that year. President Kennedy was assassinated just a few weeks later, and his successor, Lyndon B. Johnson, would escalate the war. Browne’s photograph, which is newly resonant today, enshrined the act of self-immolation as the most extreme form of protest. — Lucy McKeon

LĂȘ: I think it’s one of the most incredible monuments that exists as a photograph. [It documents] an extraordinary act of sacrifice for a cause. These days, you see [some] people protesting, and it’s all about their egos. And here, there’s no ego. It’s one of the few pictures I know that’s so violent and peaceful at the same time.

Douglas: He was there for five minutes, apparently, burning, and just didn’t flinch, didn’t say a word. This is what you do when you have no other recourse, when you feel the suppression is so severe that this is the only way you can get your statement heard.

Meiselas: It makes me think of the Napalm Girl, as well [ Nick Ut’s 1972 image of Kim Phuc Phan Thi , age 9, fleeing a napalm attack in the village of TráșŁng BĂ ng]. That moment impacted a generation. The question is, which one mobilized us further?

LĂȘ: The Napalm Girl picture, for me, represents the notion that all Vietnamese are victims of war. I started watching war movies in college, and every time the word “Vietnam” comes up, that is the image that people have in their mind. I think the monk speaks to [something] beyond himself. He’s not a victim.

7. NASA/William A. Anders, “Earthrise,” 1968

On Christmas Eve 1968, aboard Apollo 8 during its pioneering orbit of the moon, William A. Anders photographed the Earth “rising” above the lunar horizon. The picture was the first of its kind — and it was also unplanned. Anders, the youngest of the three astronauts on the spacecraft, had been tasked with taking photographs of the moon’s craters, mountains and other geological features. He spontaneously decided, however, to include Earth in the frame when he noticed how beautiful it was. “Here was this orb looking like a Christmas tree ornament, very fragile,” Anders would recall in a NASA oral history. “And yet it was our home.” His first shot was in black and white. For the next, he switched to color, which emphasized the contrast between the moon’s gray surface and the planet’s blue-green vibrancy. “Earthrise” was the first image most of humanity saw of the planet we live on, a nature photo like none before it and a reminder of how small our world really is, in comparison with the rest of the universe. As Joni Mitchell would sing of the image, on 1976’s “ Refuge of the Roads ”: “And you couldn’t see a city on that marbled bowling ball/Or a forest or a highway/Or me here least of all. 
” — E.I.

LĂȘ: “Earthrise” isn’t the first image of the Earth seen from space. There were earlier low-resolution ones in the ’40s , made from unmanned missiles or whatever. There was one made on Apollo 4, in 1967 . But I think this one, taken by a crew member on Apollo 8 the next year with a Hasselblad, is important because it’s humbling: seeing the Earth in relationship to the Moon, and thinking about us not being the only people on this Earth. Perhaps this is when we started thinking about how we should take care of our home.

Miller: Stan, you nominated a later photo, “ Sunset on Mars ” (2005).

Douglas: I’ve always had this knee-jerk response to Apollo being American propaganda somehow, part of the arms race — who’s going to get [to the Moon] first, the U.S. or the Russians? And once the U.S. got there, they lost interest. It wasn’t really about exploration, but dominance. This image on Mars is something quite extraordinary, because in effect, the camera is a prosthesis. It’s both a very artificial one and a human one. We actually extend our vision through it.

8. Ernest C. Withers, “I Am a Man: Sanitation Workers Strike, Memphis, Tennessee,” 1968

In the last weeks of his life, Martin Luther King Jr. took part in a protest of Black sanitation workers striking for safer conditions and decent wages in Memphis, Tenn. In a speech, King emphasized the connection between the United States’ civil rights battle and the struggles of poor and disenfranchised people worldwide, a message that resonated with the crowd. Their protest signs bore the phrase “I Am a Man,” a stark acknowledgment of all the ways this most basic fact was disrespected. “We were going to demand to have the same dignity and the same courtesy any other citizen of Memphis has,” one of the participants, James Douglas, recalled in a 1978 documentary titled “I Am a Man.” The defining photo of the strike was taken by the Black photojournalist Ernest C. Withers, a Memphis native who previously shot the trial of Emmett Till’s killers, and also made famous images of the Montgomery bus boycott , the integration of Central High School in Little Rock, Ark. Withers’s picture became the official record of King’s last major civil rights action. Years later, however, Withers’s own story was revealed to have been more complicated. Like King, the photographer drew the attention of the F.B.I. Unlike King, he became a paid informant. Yet he continued to produce some of the most iconic images of the movement: On April 4, 1968, less than a week after taking this photo, Withers was on the balcony of the Lorraine Motel, photographing the blood stain at the scene of King’s assassination. — L.M.

Shikeith: I think I first saw this image around the time the Million Man March was happening [in 1995]. I have a greater understanding of manhood [now] and how much of it I want to align with, and how much I don’t. But I understand how vital the need to identify as a man was in that moment.

Meiselas: I love the contrast of “I am a man,” singular, and “I am a collective.” It’s just all there: perfect distance, perfect composition. Whether or not Withers was working for the F.B.I. 


Douglas: Was he?

Meiselas: Yeah.

Douglas: And his role was to just 


Meiselas: Report on his fellow men. They paid him to spy on his colleagues. It’s a dark story. But let’s not go there.

9. Blair Stapp, Huey Newton, Black Panther Minister of Defense, 1968

In the summer of 1968, outside of the Alameda County Courthouse in Oakland, Calif., where Huey P. Newton stood trial for the murder of a police officer, supporters held up posters of him that instantly became synonymous with the Black Panther Party. The year before, Newton, the party’s co-founder and Minister of Defense, had collaborated with fellow Panther Eldridge Cleaver and the photographer Blair Stapp to stage a portrait of himself in a black leather jacket and a tipped beret, holding a shotgun in one hand and a spear in the other. He’s seated on a rattan peacock chair that recalls chairs woven by inmates in the United States-colonized Philippines decades earlier. Its oval back piece frames Newton’s head like an oversize halo. Two Zulu warrior shields are propped against the wall. Stapp’s portrait and the peacock chair itself have since become an enduring symbol of Black Power. Michelle Obama sat in one for her 1982 prom portrait . Melvin Van Peebles recreated the photograph in his 1995 film “Panther.” The visual artist Sam Durant memorialized Newton in bronze in 2004 , and Henry Taylor painted it in 2007 . After two hung juries, the murder charges against Newton were dropped in 1971. For him, the struggle was about survival — or as he put it, “survival pending revolution.” — B.E.

Shikeith: I was trying to think of images that my grandmothers revered in a way. I think this is one of those images that exists in a lot of Black domestic spaces as a symbol for strength and determination. And it has this royal demeanor that’s been continuously emulated in Black photographic practice, whether amateur or professional.

Marcoci: The beret is almost [like] Che’s.

Shikeith: You can see people replicating this pose on the wicker chair throughout Black portraiture in the ’80s and early ’90s. I’m really interested in photographs that’ve had a long-lasting effect on our daily lives.

10. W. Eugene Smith, “Tomoko in Her Bath,” 1972

In the Magnum photojournalist W. Eugene Smith’s picture of Tomoko Kamimura, 15, she is being bathed by her mother at their home, in Minamata, Japan. Kamimura had been born with a kind of mercury poisoning that would later come to be known as Minamata disease, caused by a chemical factory contaminating the city’s water and food supply for more than 30 years. Smith and his wife, the photographer and activist Aileen M. Smith, lived in Minamata in the early 1970s, taking thousands of photographs to document the toll of the disaster — 1,784 people died after contracting the disease and thousands were left with severe neurological and musculoskeletal disabilities. Images from the series were printed by Life magazine in 1972, and Kamimura’s portrait became, for a time, one of the most famous images in the world. Amid the public outcry, “rumors began to circulate through the neighborhood claiming that we were making money from the publicity,” Kamimura’s father, Yoshio, would later write, “but this was untrue — it had never entered our minds to profit from the photograph of Tomoko. We never dreamed that a photograph like that could be commercial.” The Chisso Corporation, which owned the factory, has paid damages to some 10,000 victims. Kamimura died in 1977, at the age of 21. Smith died the following year. Twenty years later, after a French TV network wanted to use the photograph, Aileen M. Smith transferred control of it to Kamimura’s family. They haven’t allowed the photograph to be reproduced since. — L.M.

Meiselas: Without this documentation by Eugene Smith, I don’t think Minamata and the mercury poisoning would ever have been confronted. So when you do choose to represent a victim, I hope it’s purposeful.

Douglas: I heartily agree. And it’s a beautiful image of a loving relationship between mother and daughter.

Vellam: Smith documented people, but he was also very conscious of what he was doing while he was documenting them. I think he took a very long time after he shot everyone to figure out what he even wanted to show from them.

Meiselas: He believed that they should be better understood.

11. Photo Archive Group, “Photographs From S-21: 1975-79”

Some photographs, taken in the darkest moments of history, end up saying very different things from what their creators intended — like the images that Stalin’s secret police took during the Great Purge, or the ones white spectators took of lynchings in the United States. One of the more extensive photographic records of an authoritarian regime comes from the Khmer Rouge army, which controlled Cambodia from 1975 to 1979 and whose genocidal purges of minority groups and political opponents led to the murder of almost a quarter of the country’s population. Before killing most of its victims, the army took their portraits, in part to prove to leaders that the supposed enemies of the state were indeed being executed. Of the nearly 20,000 people sent between 1975 and 1979 to what was known as the S-21 death camp, the Khmer Rouge’s most notorious torture center, only about a dozen survived. In 1994, the American nonprofit organization Photo Archive Group cleaned and cataloged more than 5,000 photographs taken of prisoners before their executions. A selection of the images, known as “Photographs from S-21: 1975-79,” was published as a book called “The Killing Fields” in 1996 and shown at MoMA the following year. Who was the girl pictured here? What had she seen? It’s impossible to know. And yet the regime’s photographic record offers a way into humanizing and remembering the victims of one of the most ruthless atrocities of the 20th century. S-21 is now the Tuol Sleng Genocide Museum, where a number of the images from “Photographs From S-21: 1975-1979” are on permanent display. — L.M.

LĂȘ: So these pictures were found in an archive in Cambodia [in 1993]. After the Khmer Rouge took over [in 1975], they went on a rampage, killing teachers and anyone who they felt wasn’t one of theirs. The bodies were buried in different locations. But they photographed these people before killing them. There were thousands of these pictures.

Douglas: If you want to make them disappear, why do you document them?

LĂȘ: But that’s the thing. It’s the banality of evil. It’s unconscionable, right? Civilians being just collateral damage in war. Perhaps there are other ways to speak about violence, and I think this [set of photographs] certainly does.

12. Cindy Sherman, “Untitled Film Stills,” 1977-80

Cindy Sherman was 23 when she began making her “Untitled Film Stills,” a series of 70 black-and-white staged self-portraits that explore stereotypes of women in film and mass media. As a student at Buffalo State College, where she originally studied painting, she became fascinated by performers such as Vito Acconci and Chris Burden, artists who put their own bodies center stage. Sherman also liked to dress up as stock characters for parties, purchasing clothes from flea markets and experimenting with cosmetics. In “Untitled Film Stills,” she plays the career girl, ingĂ©nue, librarian , mistress, femme fatale and runaway , alternately heartbroken, hung over, daydreaming or determined to escape a predator as though trapped in some film noir. But which film? That feeling of vague recognition was Sherman’s point, as well as that of other artists of the era experimenting with pictures from mass media, who would eventually be called the Pictures Generation, a name based on a 1977 exhibition curated by Douglas Crimp . They wanted viewers to almost recognize the images, so as to heighten the uncanny nature of their work. Sherman initially sold eight-by-ten prints from “Untitled Film Stills” for $50 out of a binder from her desk at her day job as a receptionist at the nonprofit gallery Artists Space in New York. Douglas Eklund, who organized a Pictures Generation exhibition in 2009, noted that the series “never ceases to astonish, as if Sherman knew how to operate all of the machinery of mass-cultural representation with one hand tied behind her back.” Her intuitive grasp of the self-portrait’s theatrical appeal, especially when that self could be manipulated — decades before anyone could have imagined camera filters on an iPhone — has kept “Untitled Film Stills” relevant ever since. — B.E.

Marcoci: There’s something about the “Untitled Film Stills.” It’s this relationship between still and moving images. Cindy Sherman has the capacity to encapsulate, in a single [work], a narrative. She calls on this pantheon of women’s roles from movies that we think we’ve seen, but none of them are based on an actual film still. There’s one [“Untitled Film Still #13,” 1978] where she looks like Brigitte Bardot in a head scarf from Jean-Luc Godard’s “Contempt” (1963), but she’s a librarian. She’s reaching for a book. She makes the Bardot type into an intellectual, which is [an agency] that most male Hollywood filmmakers of the time, or even a filmmaker like Godard, would not have given the real Bardot. She was able to see something about how we engage with mass media and tweak it.

Douglas: I’m not convinced about Sherman. [There’s] an art-world canonization of the work. How important was it? How influential? I don’t think it was that important or influential outside of a very small area.

Marcoci: On the other hand, if you ask people if they know about Sherman, they probably do.

LĂȘ: They do. Many young women find Sherman’s work empowering.

Marcoci: I never thought that we would just be considering photojournalism.

Meiselas: No.

Douglas: I mean, looking at the art world, I would include Ed Ruscha’s “Every Building on the Sunset Strip” [1966].

13. Ed Ruscha, “Every Building on the Sunset Strip,” 1966

As a teenager in Oklahoma City in the 1950s, Ed Ruscha delivered newspapers by bicycle daily along a two-mile route. He dreamed about making a model of all the buildings on his circuit, he later recalled in an interview with the Los Angeles Times, “like an architect standing over a table and plotting out a city.” After moving to Los Angeles for art school in 1956, Ruscha became obsessed with the city’s architecture, particularly on the Sunset Strip, that part of Sunset Boulevard that stretches for about two miles, like his old paper route, across West Hollywood. In 1966, Ruscha photographed both sides of the Strip by securing a motorized camera to the bed of a pickup truck. The result was “Every Building on the Sunset Strip,” a nearly 25-foot accordion-fold, self-published artist’s book. Today, Ruscha is most famous for his text-based paintings, many of which reference corporate logos and advertising slogans, for which he is widely celebrated as postwar America’s answer to the Dadaist nonsense movement. But his photography shares with the paintings a repetitive, deadpan humor. In addition to the Sunset Strip, Ruscha photographed swimming pools, gas stations, parking lots and apartments, and collected the images into small books that provoked the ire of critics — and fellow photographers — who deemed the work lacking in style and meaning. (“Only an idiot would take pictures of nothing but the filling stations,” the photographer Jeff Wall once complained.) But what he created was a kind of time travel, a meticulous, obsessive visual cartography of a long-lost Los Angeles. He and his brother, Paul, still make the trip to photograph the street every couple of years. — B.E.

Marcoci: I love [Ed] Ruscha, and I think we’ve barely touched on conceptual photography. Obviously superimportant, but is he really the photographer that did so much for photography through that series?

Meiselas: I know what you mean. Of course, because the photographs came way early, we rediscovered them after he became famous for painting.

Miller: Well, he’s certainly not as famous as a photographer as some people on this list, but I don’t know if we need to get hung up on that.

Douglas: I think “Sunset Strip” was extraordinary. Ruscha produces photographs governed by a hard-core conceptual procedure. In the case of “Every Building on the Sunset Strip,” the procedure is in the title and, in order to fulfill it, he had to make hundreds of stops along a Los Angeles street. But I also thought this was too inside the art world.

Miller: Maybe this is a good time to talk about Nan Goldin.

14. Nan Goldin, “The Ballad of Sexual Dependency,” 1979-2004

Nan Goldin originally presented “Ballad,” named after a song from Bertolt Brecht’s satirical musical “The Threepenny Opera,” as a series of 35-millimeter slides shown by a carousel projector in bars and nightclubs and backed by an eclectic soundtrack — from Dean Martin to the Velvet Underground. Goldin’s visual diary is itself a bohemian opera of New York’s downtown counterculture, a community freed from convention yet abandoned many times over by society; it documents sex, addiction, beauty, violence, powerful friendship, the AIDS crisis and the joyful struggle to live beyond the limits of the mainstream. Friends were photographed doing the twist at a party or preparing to inject heroin. In “Nan One Month After Being Battered” (1984), a portrait of domestic abuse, the artist’s bloodshot eye meets the lens head-on. Goldin’s “Ballad” has since been credited with inspiring everything from selfie culture to the raw, diaristic aesthetic and saturated color now commonplace across social media and in fine art. Over the years, Goldin would revise and update the series, presenting it with new images and a different soundtrack, and it would become an ubiquitous presence in galleries and museums. But because the work has so thoroughly permeated the culture, it’s easy to overlook just how radical it was when it debuted. In “ All the Beauty and the Bloodshed ,” Laura Poitras’s 2022 documentary about Goldin, the photographer describes a resistance to her art in the ’80s, “especially from male artists and gallerists who said ‘This isn’t photography. Nobody photographs their own life.’ It was still a kind of outlier act.” — L.M.

Marcoci: We’re talking about an artist who’s very much engaged with youth culture, with the cultures that transgress gender binaries. Also with the ravages of a generation that takes drugs, that loves, that dies young. “The Ballad of Sexual Dependency” is a ballad. It shows this group of people as images set to music.

Meiselas: It was radical, it was very impactful to the photographic medium. But here’s my question: Would we be choosing either Nan [Goldin] or Cindy Sherman if we didn’t know their names?

Marcoci: Did you watch the “Ballad”?

Meiselas: Of course. I watched it in 1985.

Marcoci: How many times?

Meiselas: How many times has she changed it?

Marcoci: But even that I like. You don’t need to choose one picture. It’s interesting for me when photography is not just a moment that’s frozen in time, when it has the capacity to change.

15. Wolfgang Tillmans, “Lutz, Alex, Suzanne & Christoph on Beach (B/W),” 1993

A slightly different, color image of the same people in “Lutz, Alex, Suzanne & Christoph on Beach (B/W)” was first published by i-D magazine in 1993 for an unconventional fashion story about camouflage. The German photographer Wolfgang Tillmans staged the scene in Bournemouth, England, where he’d attended art school the previous year, and captured a whorl of bodies in military fatigues, each person clasping another’s arm, thigh or chest, and all wearing camouflage patterns from different countries — a post-Cold War utopia. The black-and-white version was printed on color paper, which accounts for the warmth of its tone. On the beach, Lutz, Alex, Suzanne and Christoph appear as if from a scene in Charles and Ray Eames’s 1977 short film “Powers of Ten,” which zooms out from a sunny picnic into the farthest reaches of the universe. Tillmans’s photograph “seems to model something like chosen family,” says the curator Phil Taylor, who edited a collection of the artist’s interviews. The way Tillmans envisions family in this early portrait — as a tight embrace amid the implied violence of the outside world — is emblematic of the way he would go on to depict men kissing at gay nightclubs or activists at antiwar demonstrations, each a picture of solidarity against the odds. — B.E.

LĂȘ: I think Wolfgang [Tillmans] captured youth culture — in magazines like i-D and The Face — at a time [the early ’90s] when young people were being captured in a different way: It was very clinical and idealized, and he just came out with this very real [take on] youth culture. The pictures were a little more grainy, and I think it [changed] the way young people are seen. My students always bring up his work. I think it’s a way to photograph your family and friends and turn them into real protagonists. And I see that influence as very long-lasting.

Marcoci: What’s interesting in this image is [that] it’s four friends on a beach, dressed in camouflage. Camouflage immediately makes you think of military uniforms, of obedience, of listening to orders. But in the techno culture of these clubs in the 1990s, it had become a symbol of individuality and freedom: the exact opposite of what the uniform means.

Meiselas: This image, if I didn’t know his name, I would’ve just turned the page.

LĂȘ: I think we need a picture that speaks about youth. And I think even though this picture was made in ’93 


Miller: 
 That’s still how young people are photographed today.

16. Lee Friedlander, “Boston,” 1986, From the Series “At Work,” 1975-95

Lee Friedlander is best known for photographing America’s social landscape, from mundane street scenes in the Midwest to nudes of Madonna that were taken in the late 1970s. Between 1975 and 1995, he created six series of photographs depicting employees at different types of workplaces, including Rust Belt factories, a telemarketing call center and a New York investment firm. One of these series, commissioned by the M.I.T. Museum and produced between 1985 and 1986, looks at office workers in the Boston area who used desktop computers for their jobs. At the time, this was a fairly new development, but one that Friedlander presciently recognized would come to define not just corporate life but humanity itself. His subjects are often seemingly oblivious — or indifferent — to the presence of the camera. Likewise, his camera often omits the computers themselves, the ostensible subject of his images. Instead, the workers, sitting at brightly lit desks, are pictured from the chest up, their detached expressions familiar to any of us as they sit engrossed in (or bored by) screens just out of frame. With this series Friedlander had tapped into the dark comedy of the mundane. His influence can be seen in a generation of younger photographers who seek to question everyday life — from Alec Soth to LaToya Ruby Frazier — and whose images would mostly be viewed on screens. — E.I.

Marcoci: I love this series.

Douglas: I love it, too, but I put this in out of guilt for not having more art people in here. It’s images of these people just engaged in the world around them.

Meiselas: In autonomous labor. I remember when I first saw this series of white-collar workers in front of machines.

LĂȘ: No one had done that before.

17. LaToya Ruby Frazier, “The Last Cruze,” 2019

LaToya Ruby Frazier’s series “The Last Cruze,” named after the compact car made by General Motors, follows the 2019 closure of an auto plant in Lordstown, Ohio, that had been open since 1966. Over nine months, Frazier documented the impact one corporation can have on a community, which lost thousands of jobs. A selection of images from the series were first published in The New York Times Magazine in May 2019, and the work was later presented as a multimedia installation: More than 60 portraits and video interviews with union workers and their families were mounted to orange metal trusses at the Renaissance Society in Chicago. In the accompanying monograph, Frazier included essays by artists and critics as well as members of the local chapter of the United Auto Workers union. On its cover is this photograph, which she shot from a helicopter, showing a group of workers and their families protesting the plant’s abrupt shuttering and requesting a new product to work on. Other images show Lordstown residents in various states of mourning — wiping away tears or proudly displaying union memorabilia. Born in a Pennsylvania steel manufacturing town, Frazier embedded herself with the Ohio workers, producing one of the most detailed records of the gutting of America’s working class. “‘The Last Cruze’ is a workers’ monument,” she has said. “It is half-holy, half-assembly line.” — L.M.

Marcoci: LaToya Ruby Frazier is a true artist-activist. These workers were losing their pension plans, their health benefits, you name it. It’s a work that includes more than 60 pictures of union workers along with their testimonies, because she also did these interviews with them.

Miller: I think “The Last Cruze” might be the only complete photographic record we have of the impact that corporate decision-making has on a work force. GM skipped town, cut their costs and the people of Lordstown were left holding the bag. We have another picture, nominated by Susan, that also documents labor.

18. Sebastião Salgado, “Serra Pelada Gold Mine, State of Pará, Brazil,” 1986

One of the most striking aspects of Sebastião Salgado’s photographs of an open-air gold mine in Brazil is the scale. Several thousand men — their bodies hunched and fragile — are rendered miniature against the backdrop of a massive pit in the earth. In the photos, most of the miners are climbing into or out of that pit, holding tools or ferrying sacks up and down narrow ladders and steep slopes. In several shots, Salgado chose not to include the horizon within the frame; the viewer can’t see where the workers’ dangerous journey ends. The photographer, who was born in the state of Minas Gerais (which means “general mines”) in Brazil, spent 35 days at Serra Pelada, living alongside the miners while he took these photographs. When they were published in 1987 in The New York Times Magazine, they revealed a late-20th-century gold rush and the appalling conditions facing those at the bottom of it. In the nearly four decades since, Salgado has gone on to capture the burning oil wells in Kuwait, the genocide in Rwanda and the destruction of the Amazon rainforest. Some critics have labeled him an “aesthete of misery,” using the plight of the poor and disenfranchised to make visually striking pictures. When these images are exhibited in a fine art context, their size is so massive, the sheer aesthetics of the imagery threaten to eclipse the act of documentation. But in a profile in The Guardian this year marking his 80th birthday, Salgado responded, “I came from the third world. When I was born, Brazil was a developing country. The pictures I took, I took from my side, from my world, from where I come from. 
 The flaw my critics have, I don’t. It’s the feeling of guilt.” — E.I.

Meiselas: The scale of what he presented to us at the time was really quite amazing.

Douglas: It was like, “Holy moly, that’s still going on?”

Meiselas: Exactly.

19. Stuart Franklin, an Unidentified Man Blocking a Column of Tanks in Tiananmen Square, 1989

On June 5, 1989, as a column of tanks rolled into formation on Chang’an Avenue bordering Tiananmen Square, the Magnum photographer Stuart Franklin watched from the sixth-floor balcony of the nearby Beijing Hotel. He was holed up there with several other foreign correspondents, who were all covering the weekslong protests, led by hundreds of thousands of unarmed students, against the Chinese Community Party. Two nights before, the People’s Liberation Army had cleared the area with force; the next morning, they prevented parents from looking for students lost in the fray, and the soldiers fired live rounds even as medics attempted to rush the injured to safety. (Thousands are thought to have been killed in the protests, although an official death toll has never been released.) Suddenly, around noon on the 5th, a young man in a white shirt and dark pants, holding shopping bags in his hands, approached the first tank. On the video footage, it attempts to maneuver around him. Like a matador taunting a bull, he flings his arms in fury and, when the tank turns back, the man jumps out again. Yet the dramatic photograph Franklin took, with five tanks and a destroyed bus in the frame, draws its power from its stillness, its potential energy. (Four other photographers are known to have captured the same scene, including Jeff Widener, whose tightly framed version for The Associated Press ran on the front page of The Times.) Authoritarian regimes cannot tolerate symbolic images of resistance and, while the Tank Man — whose identity has never been confirmed — became an inspiration for pro-democracy movements across the world, he was snuffed out from official Chinese memory. Today, image searches in China for “Tiananmen Square” only turn up cheerful pictures of a tourist destination. — B.E.

Douglas: Multiple photographers shot this image because they were all in the same corner of a hotel overlooking Tiananmen Square. They couldn’t really shoot anywhere else on the square. The first time I saw this scene, it was a video.

Meiselas: Right, there was a television camera. The stills are very different. And I don’t care whose image it is. I’m thinking about the man in front of the tank and what happens when one man stands up. And I love how this looks alongside Ernest Withers’s “I Am a Man.”

20. Adam Broomberg & Oliver Chanarin, “The Day Nobody Died,” 2008

In 2008, the artist duo Adam Broomberg and Oliver Chanarin were embedded with the British Army in Afghanistan during a period that was, at the time, the deadliest week since the war began in 2001. They brought a lightproof box containing a roll of photographic paper, and, occasionally, exposed six-meter segments of the paper to the sun for 20 seconds at a time. They were creating photograms, which, as opposed to conventional war photographs, display the marks of their making but little else. The resulting works — 12 in total — set out “to create a kind of post-mortem of photojournalistic representation of conflict,” as the artists wrote when the work was first exhibited. They made these images on days when a BBC fixer was executed or a suicide attack killed nine Afghan soldiers. But they also made one on the day that the title refers to — a day with no fatalities. In a literal sense, there isn’t anything to see in the images except splashes of light as abstract as a blurry sonogram. When Broomberg and Chanarin arrived in Afghanistan, the war was in its seventh year and, by then, a surfeit of photographs depicting death and violence had long been circulating. There’s hardly consensus on what to leave out when depicting war, but there is some consensus on the need to bear witness. With their photograms, Broomberg and Chanarin found a new, unexpected, but no less emotional way of doing so. — E.I.

Miller: There were a lot of different kinds of images of war from the George W. Bush era. Nadia, you nominated Adam Broomberg and Oliver Chanarin’s “The Day Nobody Died,” which is very abstract.

Douglas: What is it?

Vellam: They did this project in Afghanistan where they took rolls of photo paper and put them outside, exposing them to the sun or the weather. Whatever would happen while the photo paper was exposed was the work. It’s about a new idea of photography, about it not depicting something specific but creating a mood. And this one was taken, as the title says, on a day nobody died, which is such an interesting and different way to talk about a conflict.

21. Richard Drew, “Falling Man,” 2001

When it was first published by The Associated Press, the photojournalist Richard Drew’s image of a man falling to his death from the World Trade Center on the morning of Sept. 11, 2001, was denounced by many readers as exploitative. Several media outlets published the image once, on Sept. 12 — including The Times, on page A7 — but it then disappeared from circulation, confined to shock websites like rotten.com. There was no shortage of graphic images of 9/11, including footage of the planes flying into the buildings. But Drew’s photo was uniquely unsettling because of its uncomfortable elegance: a single victim, framed by both north and south towers, caught in a fragile stasis before death. The image eventually began a strange afterlife as “one of the most famous photographs in human history,” according to the journalist Tom Junod, who wrote a 2003 essay in Esquire in which he attempts to identify the falling man. He couldn’t — not definitively. No one has. Recalling war photography that valorizes the unknown soldier, “Falling Man” would go on to be one of the inspirations for a novel by Don DeLillo and an opera by Daniel Levy. Long after the dust settled on the former site of the World Trade Center, the photograph of the unnamed man remains, like “an unmarked grave,” in Junod’s words, merely asking that we look at it. — E.I.

Miller: I think “Falling Man” is the defining image from the most violent day in America since the Civil War.

Shikeith: I was in middle school when 9/11 happened. Images from that day seem to seep into you. You carry them for life and they dictate certain fears and anxieties.

Miller: And then there are all the images from what happened in the years to come. The pictures of soldiers torturing detainees at Abu Ghraib military prison are arguably the most famous photographs from the war on terror.

22. Staff Sgt. Ivan L. Frederick II, Abu Ghraib Hooded Detainee, 2003

In early 2004, investigations into abuse of Iraqi prisoners by U.S. soldiers at the Abu Ghraib detention facility had already been reported by news outlets including The New York Times and CNN. But the government had kept all photographs of torture out of view — until leaked images reached CBS. Even then, the news anchor Dan Rather would claim, the network’s executives only granted permission to show them when faced with the threat of a scoop by The New Yorker’s investigative journalist Seymour Hersh. (CBS executives justified holding the photos on various grounds, including the desire to avoid retaliation against American hostages.) The Abu Ghraib photos finally appeared in both outlets later that year. Their subject matter is brutal: men stripped naked and made to form a human pyramid with soldiers grinning behind them; a hooded man standing atop a box, hooked to electrical wires. The fact that American soldiers had recorded these scenes on their personal cameras only made them more disturbing. The photos significantly shifted American public opinion on the war on terror, further demonstrating the power of an image to alter a story. They also speak to a broader shift in news photography, in which everyone — no matter their intentions — is now a potential journalist. — L.M.

Shikeith: Both “Falling Man” and the hooded Iraqi detainee have a hard-core bodily effect on me. I think there was a sort of naĂŻvetĂ© to the world I grew up in, just this idea that America is the greatest place on earth. For a moment there, we believed the myth. At least I did. When I started seeing these images, I developed a distrust in a lot of things. It only got worse. I have a very pessimistic outlook, but it sort of begins here, with these images.

23. Carrie Mae Weems, “From Here I Saw What Happened and I Cried,” 1995-96

Carrie Mae Weems’s “From Here I Saw What Happened and I Cried” is a work of appropriation that brings together 34 photographs, many of them of Black Americans, dating from the mid-19th century to the late 1960s, which collectively form a lesson on the history of racism in America. At the heart of the work are four images of people who were enslaved in South Carolina — some of the earliest known images that exist of America’s original sin — taken by the photographer Joseph T. Zealy and commissioned in 1850 by the Harvard University biologist Louis Agassiz. Originally intended to illustrate Agassiz’s baseless phrenological theories of Black inferiority, the pictures were rescaled and reframed by Weems, who also tinted them blood-red, making explicit the violence that allowed for their creation. Stored in Harvard’s archives for more than a century, Zealy’s images fell into obscurity, only to be rediscovered in 1976. After Weems used them without permission, the school threatened her with a lawsuit. “I think that your suing me would be a really good thing,” she told the university, as she later recalled to the art historian Deborah Willis. “You should, and we should have this conversation in court.” Instead of proceeding with the suit, Harvard acquired the work, further complicating the idea of ownership that Weems investigates. — E.I.

Vellam: We should talk about Carrie [Mae Weems].

Meiselas: We should definitely talk about Carrie. There are two very different options [“ Kitchen Table Series ,” 1990, and “From Here I Saw What Happened and I Cried.”]

LĂȘ: I chose the “Kitchen Table Series” [in which Weems poses as the matriarch in various domestic scenes she staged in a single room, containing little else but an overhead lamp and a table]. The kitchen table is symbolic — it’s the intimacy of the home. In a way I always felt these pictures were about people being able to be themselves, being open and visible in a way that they maybe can’t in public.

Marcoci: To me, the “Kitchen Table Series” is a true performance for the camera in a way that Cindy’s is in “Untitled Film Stills.” But “From Here I Saw What Happened and I Cried” is an amazing work because it engages with race, with slavery, with colonialism, through an archive. The subjects here were really originally presented as specimens. But what Carrie does is give a voice back to these subjects, whose voices were completely muted. She enlarges the photographs. She tints them blood-red. The whole thing becomes a poem.

Shikeith: This particular work taught me how to use photographs to tell a story. And the fact that [Harvard threatened to sue her] introduces this whole other issue about who gets to tell what stories.

24. Deana Lawson, “Nation,” 2018

The idea for “Nation” came to Deana Lawson in a dream. She was haunted by a story that George Washington’s false teeth were made from the teeth of enslaved people . For months, she kept an image of Washington’s dentures — held in Mount Vernon’s collection — on the wall of her bedroom. Lawson dreamed about a person wearing a mouth guard and wondered if she might forge a connection between the majesty of gold — the jewelry of hip-hop and the regalia of the Ashanti Kingdom — and the fact that the first president of the United States could only speak the lofty words of liberty through teeth that once belonged to the oppressed. Lawson is known for portraits she stages in homes and other intimate spaces, often decorated with a large array of objects: family pictures, children’s toys, a Michael Jackson poster. In her images, Black men and women, their skin captured in color with meticulous attention to shade and tone, appear not as documentary subjects but as vessels. “Her people seem to occupy a higher plane, a kingdom of restored glory,” the novelist Zadie Smith has written of Lawson’s photography. At the photo shoot for “Nation,” Lawson offered three hip-hop artists a selection of jewelry and a mouth guard, typically worn during dental procedures, painted gold. “Someone said that I’m ruthless when it comes to what I want,” Lawson says in an interview in her self-titled 2018 monograph. “I have an image in mind that 
 burns so deeply that I have to make it, and I don’t care what people are going to think.” “Nation” presents an endless series of questions about Black lineage, going back centuries before the nation’s founding. Lawson later printed the picture of Washington’s teeth on a card and slipped it into the edge of the work’s golden frame. — B.E.

Miller: Deana Lawson seems to be doing something similar to Weems in “Nation.”

Marcoci: I think that’s an amazing image. It’s actually a collage, with the picture of George Washington’s dentures tucked into the top right corner. She’s said photography has the power to make history and the present speak to each other.

25. Carlijn Jacobs, “Renaissance,” 2022

On July 29, 2022, when BeyoncĂ© released “Renaissance,” the first of what she’s envisioned as a three-act magnum opus (act two, “Cowboy Carter,” was released this March), the public was exhausted after two and a half years of pandemic restrictions and unprecedented change to their daily routines. They were stir-crazy and impatient for the dance floor. BeyoncĂ© embraced the sounds of house music pioneered by Black and queer D.J.s, as well as the subversive, high-gloss styling of ballroom culture. The singer appears on the album’s cover in a Giannina Azar-designed silver rope dress, sitting astride a horse covered in mirrors. The image was taken by Carlijn Jacobs, a Dutch fashion photographer interested in the art of masquerade and maximalist glamour, and alludes to both rodeo and royalty. It also conjures a range of artistic references, including Kehinde Wiley’s painting “ Equestrian Portrait of Isabella of Bourbon ” (2016); Rose Hartman’s snapshots of Bianca Jagger on a white horse at Studio 54 in 1977; and John Collier’s 1890s painting of Lady Godiva, the 11th-century Englishwoman said to have rode her horse naked through the streets as a form of protest. — B.E.

Vellam: Does anybody else feel like we’re missing a pop-culture celebrity moment? If we’re talking about images that go everywhere, and that people who live in the middle of the country all are going to look at, I don’t feel we have that.

Douglas: I think it’s important to include the idea of celebrity culture in photography. I’m not quite sure what that would be.

LĂȘ: There’s the [2017] picture of BeyoncĂ© pregnant with all the flowers .

Miller: Initially, Shikeith had also picked BeyoncĂ© from the album cover of “Dangerously in Love” (2003).

Marcoci: But sorry, why don’t we then just choose a [Richard] Avedon of a celebrity?

Vellam: Marilyn Monroe [from 1957]. But don’t we feel like we have plenty of photographs from the past? Don’t we want to think about what celebrity is now?

Miller: What’s the iconic pop culture image from the last five years?

Douglas: Is there a Kardashian image?

Vellam: I can’t, because I hate them so much. But yes, you want the thing of [Kim Kardashian] when she broke the internet with her butt [an image that ran on the cover of Paper magazine in 2014].

Douglas: I’m going back to BeyoncĂ©, because [you want] an image of a celebrity who’s not a person but an image. She’s like a simulacrum somehow.

Vellam: With her “Renaissance” cover, suddenly she was plastered everywhere. It was all over the city.

Douglas: I’d buy that.

Shikeith: I think it’s very important that she released this album and highlighted Black queer contributions to music in the culture because, very frequently, those same contributions are erased or attributed to someone else. Especially in pop culture.

Marcoci: Can you hold it up on your phone?

Vellam: Yeah. I listen to it all the time.

It was not first presented at the Renaissance Society. The article also misstated the date of the Tank Man photograph by Stuart Franklin in Beijing; it was June 5, 1989, not June 4.
