Today at the lesson: Projects: Forms of pollution Global warming and Greenhouse effect Eco problems in my home town Grammar: First Conditional Simple Present Passive Present Perfect Listening: London
Pollution There is no denying that pollution in its many forms is one of the most serious environmental problems. From the very start I should say that the word pollution means making water, air and soil dirty and dangerous for people and animals to live in. In my opinion, pollution is the result of the harmful effect of the human activity.
A lot of lakes, rivers and seas are used as a dump. Many plants and factories throw away their industrial waste into the water. There is not enough oxygen in the water. Fish and reptiles cant live in poisoned water. They leave their habitats and die. Water pollution
Air pollution Every year the worlds industry pollutes the atmosphere. The polluted air mixes with the rain and causes holes in the ozone layer.
Chemical pollution of atmosphere also causes acid rains. You certainly know that most of the pollution in big cities comes from cars and buses. To make the air clean we need good filters at factories and plants, as well as on cars and buses.
Nuclear pollution Many seas are used for dumping nuclear waste. The Pacific Ocean, especially, has suffered from nuclear pollution because the French Government tested nuclear weapons there. Besides nuclear power stations can have accidents and cause nuclear pollution. It cant be seen, but its effect can be dangerous.
The nuclear accident in Chernobyl has seriously aggravated the ecological situation in Belarus. Both clean air and clean water are necessary for our health. If people want to survive, they must solve these problems quickly. Some years ago our government decided to build the Nuclear Power Station not far from Kostroma but all people of our region were against it. So the Nuclear Power Station wasnt built.

In the last few years the world has been full of stories of hurricanes, floods, droughts and other disasters caused by the weather. Scientists agree that something very serious is happening to the world weather.
They now think that in the future the globe may get warmer. Winters have already become warmer because we are producing too many greenhouse gases. People breathe in oxygen and breathe out carbon dioxide. We also make carbon dioxide when we burn woods or drive cars.
The matter is that carbon dioxide and other toxic gases work like glass in the greenhouse. They let heat get in it but dont let much heat out. Trees take these gases from the air and produce oxygen. But in the last few years people have cut down a lot of rainforests. This means fewer trees and more carbon dioxide. So the atmosphere has become warmer. Other dangerous gases are in refrigerators and aerosol cans. These gases hold the heat which cant go back into space.
