Air pollution is a chemical, particulate matter, or biological agent that modifies the natural characteristics of the atmosphere.

Worldwide air pollution is responsible for large numbers of deaths and cases of respiratory disease.[verification needed] While major stationary sources such as power plants are often identified with air pollution, the greatest source of emissions is actually mobile sources, mainly automobiles.[verification needed] Greenhouse gases such as carbon dioxide, which contribute to global warming, have recently gained recognition as pollutants and internationally laws are being developed to reduce these emissions.
