4.What do all people need?
Текст:
About two hundred years ago people lived in harmony with nature, because industry was not much developed. But progress does not come to a standstill. Considerable advances were made by people in different areas of science. However, there exists the dark side of the picture. Now industrially developed states can not ignore the problem of environmental protection. The ecocide is increasing constantly. The contradictions between man and nature are dramatic. The main aim in the policy of environmental protection is development of technology to control atmospheric and water pollution, the study of man's influence on climate, biological and genetic consequences of pollution, protection of rare and vanishing plants and animals and protection of nature as a whole (слайд №3).

Let's begin with the snowball to revise the words you know. Today you'll work in groups. One person from the group names the word, the other repeats his word and adds his own. e. g. environment; environment, dump; environment, dump, pollution and so on.

Take card №1. Read the text and try to understand it. Be ready to answer my questions and do some tasks. (слайд №4) You have 6-7 minutes.

We need our planet cleaner and healthier

The Earth is our home, but much of it is dirty and dying.

By the year 2030, scientists report that 25% of all animals, birds, fish and insects may be extinct.

Every year man cuts down more trees to provide paper, wood, medicines, mineral fuel. But it's not only trees and forests which are disappearing. Animals, insects and flowers are destroyed, too. Is there any solution? People should protect certain areas and plant new forests.

Cars and factories are very dirty. They can also be dangerous for people, wildlife and environment.

One of Europe's and North America's most serious pollution problems is "acid rain". This happens when factories send gases and chemicals into the air. There they mix, and the mixture is carried for hundreds of miles by the wind and finally falls back to earth. This "acid rain" kills fish and trees. It slowly destroys everything. Industrial countries should control their level of pollution and try to reduce the acid rain effect.

At the moment, 94% of the world's energy comes from oil, gas and coal. But these "fossil fuels" won't last forever. There's only enough oil and gas for the next 50 years. Coal will last longer - perhaps about 300 years. And then? Well, one answer is nuclear energy. But today, after Chernobyl, many people think it's too dangerous. There are four solutions.

They all use natural energy in the environment: wind energy, wave energy (from the sea), and geothermal energy (from "hot" rocks under the ground). It's clean and natural, but there is another problem: they all rather expensive.

Today, many scientists and world leaders realize that the Earth is in danger. Either we stop killing the Earth or we kill ourselves. We need a cleaner, healthier planet.
