The Ozone Layer
Read the passage carefully and answer the questions that follow:
It’s becoming very dangerous to sit in the sun. If you have a fashionable suntan, it doesn’t necessarily mean that you have lots of outdoor activities – but it does mean that you’re in greater danger of getting skin cancer and cataracts.
The ozone layer, which protects us from the sun’s dangerous ultraviolet rays, is progressively deteriorating. In February 1992, a scientific report said that people in Canada, Northern Europe and Russia were in serious danger.
In 1985, the news of the destruction of the ozone layer in the South Pole alarmed people in the Southern Hemisphere. In Australia, there are now three times more cases of skin cancer than in the past. In New Zealand, teachers tell school children to wear hats and not to sit in the sun. What causes the destruction of the ozone layer? Mostly chlorofluorocarbons (CFCs), Aerosol sprays, refrigerators, air conditioners, as well as industrial chemicals, send chlorofluorocarbons into the atmosphere.
Governments are now trying very hard to forbid CFCs, but it will be expensive and difficult to do so. Alter the first ozone alarm in the Southern Hemisphere, ecologists all over the world asked governments to take strict measures immediately. Some governments did, but not soon enough. Other countries believe that they have other problems which are more important. Now stricter measures are going to be taken, but already a lot of damage has been done.
