What causes air pollution? Air pollution is caused by a wide variety of things. The earth is great at cleaning the air on its own. However, air pollution has grown so much, the earth can no longer clean all of it. This is starting to have adverse effects on the environment such as causing acid rain, smog and a wide variety of health problems.

Factories Factories, office buildings, homes and power- generating stations burn fossil fuels, which cause air pollution. The burning of oil and coal (fossil fuels) also contributes to smog. This air pollution destroys plants, damages buildings and creates oxidation on iron.

Pesticides Pesticides used to kill indoor and outdoor pests, insecticides used to kill insects and herbicides use to kill weeds all cause air pollution.
