This fragile planet

1)What does the word environment mean?
The word environment means everything what is around us. Some people live in a town for others, other in the countryside.

2) What are the most serious environment problems?
pollution in its many forms (water pollution, air pollution, nuclear pollution)
noise from cars, buses, planes, etc.
shortage of natural resources (metals, different kinds of fuel), the growth of population.
destruction of wildlife and countryside beauty

3) What makes sea water dangerous nowadays?
There is no ocean or sea, which is not used as a dump. Many seas are used for dumping industrial and nuclear waste. This poisons and kills fish and sea animals. Many rivers and lakes are poisoned too.

4) Why is it dangerous to dump industrial waste in the sea?
Many rivers and lakes are poisoned. 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 produce a lot of waste and pour it into rivers.

5)Why was the Statue of Liberty in New York damaged?
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.

6)Where does air pollution in the cities mostly come from?
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 Ukraine. 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.

7)Why is it not safe to be in direct sunlight in certain places?
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.

8)Why are nuclear power stations dangerous?
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 Ukraine. Nuclear pollution cannot be seen but its effects can be terrible.
