You need to breathe to stay alive. But how clean is the air you breathe? If you breathe dirty air, you are more likely to develop health problems and become ill. Plants and animals need clean air too. A lot of the things that make our lives more comfortable such as cars, electricity and heating, create bad gases which make the air dirty. The problem of air pollution started with the burning of coal in homes and factories. Dirty air is called 'polluted air'. 'Air pollution' is what we say to describe all bad gases in the air that we breathe and that are dangerous for us. But do not worry! Not all gases are bad!
