There is no ocean or sea which is not used as a dump. The Pacific Ocean, especially, has suffered from nuclear pollution because the French Government
tests nuclear weapons there. Many seas are used for dumping industrial and nuclear waste. Britain alone dumps 250,000 tons of industrial waste straight into the North Sea. This poisons and kills fish and sea animals. “Nuclear-poisoned” fish can be eaten by people.

Many rivers and lakes a poisoned too. Fish and reptiles can’t live in them. There is not enough oxygen in the water. In such places all the birds leave their habitats and many plants die. If people drink this water they can die too. It happens so because factories and plants produce a lot of waste and pour it into rivers. So they poison the water. Factories used clean water. After the water is used it becomes poison which goes back into rivers, lakes and seas.

Air Pollution

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 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 can’t 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 out health. 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.
