What are the sources of air pollution

Air pollution has two main sources: anthropogenic (man-made) and natural. Man-made sources of pollution include factories, cars, motorcycles, ships, incinerators, wood burning, oil refining, chemicals, consumer product emissions like aerosol sprays and fumes from paint, methane from garbage in landfills, and pollution from nuclear and biological weapons production and testing. Natural sources of pollution may include dust, methane from human and animal waste, radon gas, smoke from wildfires, and volcanic activity.
