UNIT 8: ENVIRONMENTReading

Fill in the blanks with the correct word in the bracket to complete the following text.

Many places around the world have problems with air pollution. Power stations, factories, lorries, and cars are part of modern life. But their fumes make the air . We have to breathe that air but it is to our health. The places with the most pollution are usually cities. Doctors say that city children have weaker lungs than children from the countryside. And they think that thousands, probably millions, of children and old people die every year because of polluted air. One way to air pollution is that instead of traveling by car or motorbikes, you can go on foot or bicycle. Cycling and walking keep you fit. They wake up your brain in the morning too, so you can get better at school. Another way is to plant more trees in your garden, your park or at school. Trees take some of the pollutions out of the air.
