Causes+of+Air+Pollution+08

There are both natural and human causes of air pollution, though the latter is more responsible for the problems associated with air pollution due to its quantity as well as its concentration. According to ThinkQuest, “f orest fires, volcanic eruptions, wind erosion, pollen dispersal, evaporation of organic compounds, and natural radioactivity are all among the natural causes of air pollution.” The primary cause of manmade air pollution is fossil fuel consumption. Large quantities of coal, oil, and natural gas are used in and the generation of electricity and for transport, and “these two sources are responsible for about 90% of all air pollution in the United States .” Industrialization is responsible for the widespread use of fossil fuels.
