C. Now look at this essay and complete the gaps with one of the words or expressions from Tasks A and B. In some cases, more than one answer may be possible. You may need to change the form of some of the words. ‘Environmental degradation is a major world problem. What causes this problem, and what can we do to prevent it?’ There is no doubt that the environment is in trouble. Factories burn 1__________________________
which produce 2__________________________ , and this kills trees. At the same time,
3__________________________ gases rise into the air and contribute to 4__________________________ ,
which threatens to melt the polar ice cap. Meanwhile farmers clear huge areas of
5__________________________ in places such as the Amazon to produce feeding land for cattle
or produce wood for building. Rivers and oceans are so heavily 6__________________________ by industrial
waste that it is no longer safe to go swimming. Cars pump out poisonous 7__________________________
which we all have to breathe in. 8__________________________ and overfishing are killing off millions
of animals, including whales, elephants and other 9__________________________ . In fact, all around us, all
living things large and small which comprise our finely balanced 10__________________________ are being
systematically destroyed by human greed and thoughtlessness.
There is a lot we can all do, however, to help prevent this. The easiest thing, of course, is to
11__________________________ waste material such as paper and glass so that we can use it
again. We should also check that the things we buy from supermarkets are packaged in
12__________________________ packaging which decomposes easily. At the same time, we should
make a conscious effort to avoid foods which are 13__________________________ (at least until
someone proves that they are safe both for us and for the environment). If you are truly
committed to protecting the environment, of course, you should only buy 14__________________________
fruit and vegetables, safe in the knowledge that they have been naturally cultivated. Finally, of course,
we should buy a small car that uses 15__________________________ which is less harmful to the
environment or, even better, make more use of public transport.
The serious 16__________________________ , however, do much more. They are aware of the global issues
involved and will actively involve themselves in 17__________________________ by making sure our forests
are kept safe for future generations. They will oppose activities which are harmful to animals, such
as 18__________________________ . And they will campaign to keep the 19__________________________
around our towns and cities free from new building.
We cannot all be as committed as them, but we can at least do our own little bit at grass roots level.
We, as humans, have inherited the earth, but that doesn’t mean we can do whatever we like with it.
