e are slowly destroying the earth. The seas and rivers are –––––––––– dirty to swim in. There is –––––––––– smoke in the air, it is unhealthy to live in many of the world’s cities. In one well-known city, for example, poisonous gases from cars pollute the air –––––––––– that traffic policemen have to wear oxygen masks.
We have cut down –––––––––– trees that there are now vast areas of wasteland all over the world. As a result, farmers in parts of Africa cannot grow –––––––––– to eat. In certain countries in Asia there is –––––––––– little rice.

Task 3.1. Read the following paragraph carefully.
The world’s oceans are so vast that they can cope with the present level of pollution. However, little is known about the long-term effects of such slow poisoning. The most serious problem of modern times is that man is destroying the earth’s natural resources, and transforming huge areas into wasteland. As a result, it is becoming extremely difficult to grow enough to feed the world’s rapidly increasing population. A way of protecting all the wildlife on the earth must also be found as many species are in danger of disappearing completely from the face of the earth. The dangers, however, are not confined solely to the land and the sea. The smoke in the atmosphere, for example, is increasing so much that the amount of sunlight has been reduced in many cities. Man’s whole environment is being changed in a serious way.
