Air pollution is a cause of ill health in human beings. In a lot of countries, there are laws

limiting the amount of smoke that factories can produce. Although there is not enough

information on the effects of smoke on the atmosphere, doctors have proved that air pollution

causes lung diseases.

The gases from the exhausts of cars have also increased air pollution in most cities. The

lead from petrol produces a poisonous gas that often collects in busy streets surrounded by high

buildings. Children who live there cannot think as quickly as other children, and are clumsy

when they use their hands.

There are long-term effects of pollution. If the gases in the atmosphere continue to

increase, the Earth’s climate may become warmer. A lot of ice near the Poles may melt and

causes serious floods.
