2.8 Read the following four short texts and answer the questions:

1 Which text:

● says about the influence of exhaust fumes?

● gives information about radioactive pollution?

● worries about infertile lands?

2 What plants can survive only in clean air?

3 What are special electronic signs designed for?

4 How do you understand the phrase: “to combat a problem”?

 

A LICHEN POLLUTION TEST

Plants called lichens are sensitive to air pollution, especially the air’s acidity, so you can use their presence or absence to see how clean your air is. Shrubby and leafy lichens only survive in clean air. In the most polluted areas there are none at all. Look for lichens on walls, stones and trees, and use this scale to rate the air quality.



POLLUTION

Pollution is now a major problem in marine ecosystems. Over 80% of this comes from land-based activities, e.g. sewage and industrial waste. Conditions are worst in enclosed areas like the Mediterranean and the North Sea, where levels of pollution are now so high that wildlife and human health are threatened.

Drum containing – dangerous radioactive nuclear waste dumped at sea. Measures are finally being taken to combat this international problem, but it will be a long and difficult job.

TRANSPORT AND POLLUTION

Pollution from the ever-growing volume of vehicle exhaust is making life more and more unpleasant in many of the world’s major cities. Ozone, carbon monoxide, hydrocarbons and lead and dust particles all endanger the health of the cities’ people and wildlife.

The removal of lead from petrol and the use of devices known as three-way catalytic converters to control exhaust fumes are two ways of lessening the problem.

In Tokyo, Japan, special electronic signs show the levels of noise and air pollution.

 

SOIL EROSION

Most of the earth’s surface is covered by a layer of soil, ranging from 0,5cm thick in mountainous regions to 2m in cultivated areas. We all depend on this thin layer for our food supplies, yet everywhere it is threatened by soil erosion.

Over-grazing, poor irrigation, intensive farming and the destruction of tree cover mean that vital topsoil is left exposed, and much is being blown or washed away. If this continuous, we may not left to grow enough food.
