Causes of Air Pollution | Class 12 Biology | CBSE Board | Home Revise
Air pollution can be caused by both man-made and natural causes, although the contribution by these natural causes is pretty negligible.
The main culprit of air pollution is man-made sources of air pollution. The single most harmful source of air pollution is the unchecked burning of fossil fuels by mankind. Fossil fuels are used in almost every process of industrialization, manufacturing, transport, and energy generation. In rural areas, a major source of pollution is the practice of unchecked crop burning. In moderation, this is actually a useful tool in farming but uncontrolled crop burning causes significant air pollution.
