Q:

How does air pollution affect the environment?

A:

Quick Answer

Air pollution affects the environment by causing acid rain, reducing visibility, damaging plants and animals, and contributing to climate change. It has a negative effect on biodiversity and the survival of species. Air pollution is caused by both particulate and gaseous pollutants.

Toxic air pollutants, such as sulfates, nitrates, dust, lead and mercury, accumulate in the food chain and harm plant and animal species. These pollutants emanate from industries, power plants and pesticide applications.

Acid rain is formed when nitrogen oxides and sulfur dioxide react with oxygen and water in air to form acidic compounds. These compounds acidify streams, lakes and the soil, causing chemical alteration and damage to the ecosystem. Acid rain also corrodes buildings and other materials.

Air pollutants, such as carbon dioxide and methane, cause climate change by depleting the ozone layer, leading to increased amounts of ultraviolet radiation on the Earth’s surface. Excessive heat causes damage to crops and diseases, such as cataracts and skin cancer, in humans.

Greenhouse gases are released from fossil fuels, such as natural gas and gasoline. Particulate pollutants in smoke and smog are the cause of loss of visibility in areas with high levels of air pollution. Air pollution also emanates from natural sources, such as volcanic activity, dust storms and forest fires.

  • Q:

    Why are fossil fuels bad for the environment?

    A:

    Burning fossil fuels negatively affects the environment because they release carbon dioxide and other gases that trap heat in the Earth's atmosphere, which contributes to global climate change. According to the Union of Concerned Scientists, the burning fossil fuels during the last 150 years has increased atmospheric carbon dioxide levels by 25 percent. Levels of methane and nitrous oxide have also increased.

    How does coal affect the environment?

    A:

    Mining and using coal for power significantly impacts the environment causing pollution of the air, water table and the ground. As time goes by, the air pollution also contributes to change in the climate, creating more temperature extremes, particularly in terms of heat waves. These types of damage for the environment mean that, even though coal is cheap to mine and produce, it is definitely worth looking for other sources of power that are cleaner.

  • Q:

    Why is air pollution a problem?

    A:

    Air pollution is a problem because it can cause damage to animals, trees, plants, crops and water sources in the environment. Pollution in the air causes problems for aviation because it reduces visibility, while also being responsible for damaging buildings and other structures. Pollutants in the air can end up in natural water supplies that humans use for drinking, which can result in water that is toxic and unhealthy for humans to consume.
