Ecological problems

3. Air pollution is a community problem
Air pollution is a community problem. Cars, trucks, buses and airplanes are the worst polluters. They send partly burned gases into the air. Air can be also polluted by smoke and gases from factories. Dirt, smoke, and gases in the air may be carried away by wind and by air currents, or settle over as a blanket of smog.

Pesticides are often used to kill insects and weeds in cities or on farms. Polluted water can spread many diseases.
