many greenhouse gases. This gases hold heat. Trees and plants help to take gases, such as carbon dioxide from the atmosphere, but we have now destroyed too many trees. Polluting gases fall as acid rains. Smoking chimneys and car exhaust pipes are pumping tons of rubbish into the air all the time, and we breath it in.

earth. It protects us from the dangerous rays of sun. But if ozone comes close to earth, in acid rains, for example, it is also very dangerous itself and causes diseases. There are now holes in the ozone layer because there are too many “greenhouse” gases. Scientists say there are over the South Pole and over New York.

the ice has been melting, the level of the sea is slowly rising. Scientists say that in the year 2050 some parts of Great Britain will be under the sea. A giant iceberg, the size of Hong Kong, is slowly melting. It is the world’s largest iceberg. It broke away from Antarctic. It was 152 km long and 35 km wide. Now it is 10 km shorter because it is melting.

be told:

other species of animals and plants have become extinct or endangered. The Blue Whale, the Panda, The California Big Tree are on the verge of extinction now. Gone forever are dinosaurs, passenger pigeons, California grizzly bears. Elephants, jungle-cats and Asian rhinoceroses are being killed off their ivory tusks, furs, or horns.

New Yorkers are so concerned about the problem that the city has policemen who check through people’s dustbins. If they find anything that could have been reused they fine the owners.

disappear naturally:

Cigarette butts – 1 – 5 years
Aluminium cans – 500 years

Plastic bags – 10 – 20 years
Plastic photo-film containers – 20 – 30 years
Nylon fabric – 30 – 40 years
Rubber boots – 50 – 80 years
Orange and banana peels – about 2 years
Plastic bottles - indefinitely

Chernobyl shows it can go wrong. Nuclear weapons can destroy the world. Nuclear weapon tests increase the amount of radiation in atmosphere. Nuclear power produces high-level radioactive waste which can be dangerous for thousands of years.
