Some Causes of Air Pollution

The Earth is a marvelous structure that is capable of cleaning up to a certain amount of air pollution, but mankind has made such a big mess with pollution that Earth by itself will not be able to clean. One big source of air pollution is manufacturing. This source of pollution releases particulate matter, and harmful chemicals into the atmosphere. Factory exhaust includes sulfur oxides, nitrogen oxides, carbon monoxide and dioxide, as well as volatile organic compounds and particulates( in other words: BAD STUFF). A whopping 0% of the Earth's ecosystem has remained unaffected by human pollution. Combustion engine exhaust is also a huge source of air pollution. Combustion exhaust can be created by cars, trucks, and jet airplanes. Factories, office buildings, homes, and power generating stations which burn fossil fuels to cause pollution. Combustion exhaust releases gases like carbon monoxide, nitrous oxide, and gaseous oxide. Petroleum refineries pollute the air by releasing various harmful particles and hydrocarbons. High voltage power lines that are not insulated also cause air pollution. Pesticides and insecticides also cause air pollution. Fertilizer dust that is used to fertilize plants is a air pollutant. Mining operations cause air pollution by releasing particles into the air.

Air Pollution Effects On The World

Air pollution is a huge problem in the world. In places like Beijing it is recommended that you don't breathe because the air pollution is so bad, but in places like the mid-western United States, air pollution is not that big of a problem. In Beijing it is recommended that infants and  elderly people stay indoors.
The Chinese authorities have been desperately attempting to improve the air quality there, but it has been recently concluded that such work as that will take decades.
