E) Read the paragraphs below and the summary which follows
Air pollution is a cause of ill-health in human beings. In a lot of countries there are laws limiting the
amount of smoke which factories can produce. Although there isn't enuogh information on the effects of
smoke in 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 in petrol
produces a poisonous gas which often collects in busy streets surrounded by high buildings. Children who
live in areas where there is a lot of lead in the atmosphere can't think as quickly as other children and are
clumsy when they use their hands.
There are other long-term effects of pollution. If the gases in the atmosphere continue to increase
the earth's climate may become warmer. A lot of the ice near the Poles ma melt and may cause serious
floods.
