There are a number of natural sources that cause air pollution.

1. Volcanic eruptions: Volcanic eruptions release toxic gases, ash, and heat in enormous quantities which pollute the air.

3. Forest fires: They release harmful fumes and suspended particles in the air.
4. Dust storms: Dust storms put dust particles in the air which pollutes the air.
