  Deforestation

  Our forests are disappearing because they are cut down or burnt. If this trend continues, one day we won't have enough oxygen to breathe.

  Pollution water

  The seas are in danger. They are filled with poison: industrial and nuclear waste, chemical fertilisers and pesticides. The Mediterranean is already nearly dead; the North Sea is following. The Aral Sea is on the brink of extinction. If nothing is done about it, one day nothing will be able to live in the seas

  Extinction animals

  Every ten minutes one kind of animal, plant or insect dies out for ever. If nothing is done about it, one million species that are alive today may soon become extinct.

  Слайд 7

  Air pollution

  Air pollution is another serious problem. In Cairo just breathing the air is dangerous — equivalent to smoking two packs of cigarettes a day. The same holds true for many Russian cities. Factories emit tons of harmful chemicals. These emissions have disastrous consequences for our planet. They are the main reason for the greenhouse effect and acid rains. An even greater threat are nuclear power stations. We all know how tragic the consequences of the Chernobyl disaster are.
