AIR POLLUTION

When the Americans decided to clean up the Statue of Liberty in 1986, the first thing they had to do was to make a hole in her nose and take away the acid rain that had collected inside. The polluted air of New York had mixed with the rain and damaged the Statue badly. And you certainly know that most of the pollution in big cities comes from cars and buses.

More and more often people are told not to be in direct sunlight, because ultraviolet radiation from the sun can cause skin cancer. Normally the ozone layer in the atmosphere protects us from such radiation, but if there are holes in the ozone layer ultraviolet radiation can get to the earth. Many scientists think that these holes are the result of air pollution.

Nuclear power stations can go wrong and cause nuclear pollution. This happened in Windscale in Britain, in Three Mile Island in the USA and Chernobyl in the former Soviet Union. Nuclear pollution cannot be seen but its effects can be terrible.

To make air clean again we need good filters at nuclear power stations, at factories and plants and also in cars and buses.

Both clean air and clean water are necessary for our health. If people want to survive they must solve these problems quickly. Man is beginning to understand that his environment is not just his own town or country, but the whole earth. That's why people all over the world think and speak so much about ecology.

Prove the following with the help of the text.

1. Nowadays there are a lot of environmental problems.

2. Direct sunlight can be dangerous.

3. Nuclear power stations can cause a lot of trouble.

4. Man should solve ecological problems as soon as possible.
