Air pollution is a chemical, physical (e.g. particulate matter), or biological agent that modifies the natural characteristics of the atmosphere. The atmosphere is a complex, dynamic natural gaseous system that is essential to support life on planet Earth. Stratospheric ozone depletion due to air pollution has long been recognized as a threat to human health as well as to the Earth's ecosystems.

Worldwide air pollution is responsible for large numbers of deaths and cases of respiratory disease. Enforced air quality standards, like the Clean Air Act in the United States, have reduced the presence of some pollutants. While major stationary sources are often identified with air pollution, the greatest source of emissions is actually mobile sources, principally the automobile. Gases such as carbon dioxide, which contribute to global warming, have recently gained recognition as pollutants by some scientists. Others recognize the gas as being essential to life, and therefore incapable of being classed as a pollutant.

There are different types of air pollution. For instance when Nitrous oxide is releases from certain factories, like those who cure leather, it can mix with ozone O3 and form photochemical smog. Another form of air pillution comes from the exaust of cars and this can cause the formation of greenhouse gasses which cause global warming

Earth, Water, hearth, Air, Ether, ideas, Intelligence and fake ego—all at the same time those 8 characterize the Lord's separated cloth energies. besides those, there is yet another, stronger means of God, which consists of the living entities (spirit souls interior those cloth bodies) who're exploiting the components of this cloth, inferior nature.

air pollution comes from a lot of different sources, but mostly car emissions, and factory chemical emissions which can also cause acid rain.

It comes from human industry and automobiles. Contrary to popular belief it has little effect on the earths climate. It just makes life unpleasant for humans which is kind of like just deserts.

Deforestation, when people use gases in their cars, even when you use a hair dryer!!! Also, some of it comes from use of fertilizers.
