Pollution and Environment

People are more worried about the environment (1) as a result of the harmful (2) effects of human activity. Some of these activities cause pollution (3) and some are destroying (4) the environment. Here are some of the problems:

1. Recent research shows that there is now a hole in parts of the ozone layer (5).

2. Global warming (6).

3. Acid rain (7) caused by smoke from factories.

Because of these problems there are many groups of people often called as greens (8). Common causes of damage are the following:

1. smoke from factories.

2. dumping (9) industrial waste (10) in seas and rivers.

3. aerosol cans (sprays) — they contain a chemical which can damage the ozone layer.

4. cutting down tropical rainforest (e. g. The Amazon).

How can we help?

Recycle (11) bottles, newspapers, etc. We shouldn’t simply throw them away!

Plant more trees.

Don’t waste resources, e. g. water, gas.

V. Reading for details.

Acid Rains

Every year more plants and animals disappear never to be seen again. Strangely, it is the most intelligent but most thoughtless animal that is causing most of the problems — man. Nature is very carefully balanced and if this balance is disturbed, animals can disappear very fast. Every day, thousands of species of animals get closer to extinction.

In many lakes the fish are dying. Fishermen are worried because every year there are fewer fish, and some lakes have no fish at all. Scientists are beginning to get worried too. What is killing the fish?

The problem is acid rain. Acid rain is a kind of air pollution. It is caused by factories that burn coal or oil or gas. These factories send smoke high into the air. The wind often carries the smoke far from the factories. Some of the harmful substances in the smoke come down with the rain hundreds of miles away.

The rain in many places isn’t natural and clean any more. It’s full of acid chemicals. Acid water hurts when it gets into your eyes. It also kills the plants and animals that usually live in lake water. That is why the fish are dying in lakes.

But scientists are finding other effects of acid rain. In some large areas trees are dying. Not just one tree here and there, but whole forests. At first scientists couldn’t understand why. There were no bugs or diseases in these trees. The weather was not dry. But now they think that the rain was the cause. Some kinds of trees cannot live in the soil that is very acidic.

Now scientists begin to study the effects of acid rain on larger animals. If even deer are hurt by the rain, what about people? It’s a very important question for us all.

Water Pollution

To see the effects of pollution in rivers, just have a look at the Clyde * or the Thames * near to the sea and compare it with the same river a few kilometres away to the hills, before factory waste has been flowing into it.

A hundred years ago you could catch eatable fish in rivers like the Thames and the Clyde. Now factories and homes are put­ting waste materials which are poisons ¹ into these rivers.

Large cities on the Great Lakes of North America are letting different wastes flow into the water. These wastes, added to the mud ² brought down by the rivers, are speeding up ³ the process by which a lake becomes useless for shipping.
