Презентация на тему: «Экология»

• The world environment means simply what is around us. Some people live in a town environment; for others, their environment is the countryside.

• But the air we breathe, the soil on which we stand and walk, the water we drink are all part of the environment.

Nowadays people understand how important it is to solve the environmental problems that endanger people’s lives. The most serious environmental problems are:

• Pollution in its main forms (water pollution, air pollution, nuclear pollution);

Emission of harmful substances into the air by plants

• Noise from cars, buses, planes, etc.

• Destruction of wildlife and the beauty of the countryside

Felling of forests

Poaching

• Shortage of natural resources (metals, different kinds of fuel);
• And the growth of population.

There is no ocean or sea which is not used as a dump. The Pacific Ocean, especially, has suffered from nuclear pollution because the French Government test nuclear weapons there.

• Many seas are used for dumping industrial and nuclear waste. Britain alone dumps 250,000 tons of industrial waste straight into the North Sea. This poisons and kills fish and sea animals. «Nuclear-poisoned» fish can be eaten by people.

• Nuclear power stations can go wrong and cause nuclear pollution. This happened in Windscale in Britain, in Three Mile Island in the USA and Chernobyl in the former Soviet Union. Nuclear pollution cannot be seen but its effects can be terrible.

Radiation accident in Windscale, Britain 1957

• Radiation accident in Three Mile Island in the USA

• Radiation accident in Chernobyl

Unfortunately, later our technical civilization thinking only of material goods succeeded in destroying Nature and creating the ecological crisis on our planet.

Both clean air and clean water are necessary for our health. If people want to survive they must solve problems quickly. Man is beginning to understand that his environment is not just his own town or country, but the whole earth. That’s why people all over the world think and speak so much about ecology.
