What causes air pollution?

Air pollution is caused by a variety of factors, including:

1. Emissions from vehicles: Cars, trucks, and other vehicles release pollutants such as carbon monoxide, nitrogen oxides, and particulate matter into the air.

2. Industrial activities: Factories and power plants emit pollutants such as sulfur dioxide, nitrogen oxides, and particulate matter into the air.

3. Agricultural activities: Farming practices such as burning crop residues and using fertilizers can release pollutants into the air.

4. Deforestation: Cutting down trees and clearing land for development releases pollutants into the air.

5. Household activities: Burning wood or other fuels for heating and cooking can release pollutants into the air.

6. Natural sources: Volcanic eruptions, wildfires, and dust storms can also contribute to air pollution.
