T. Ok! The protection of the Earth is global. Why are people worried about the environment? What happens on our planet?

P. About two hundred years ago man lived in harmony  with nature because industry was not much developed. Nature seemed to be endless. Far from it as it turned out.

Now millions of cars and factories pollute and spoil the air we breathe in. Pollution is changing over big cities like an ugly brown cloud. People need wood and paper so we cut down forests.

 I. Dialogue: 

Ec: Global warming  as the “greenhouse effect” is the result of the pollution of air, land and water. The temperature of the Earth’s atmosphere has increased   very much. Global warming is one of the climatic effects of polluted. It can cause melting of polar ice, rising of the sea level and flooding.

P. I’d like to know why some species of animals and plants disappear from the Earth?

Ec: It’s the result of the environmental pollution. Some animals disappeared. For example pandas which live in the jungle and white bares   which live in the Arctic. White bears eat fish . if people pollute rivers and seas, animals die. Pollution means  death to the ocean. Pollution kills whales. It kills planet and fish. Experts believe life in the ocean will be destroyed within 25 years. Remember  the ocean dies, the  man will be die too. 

II. Dialogue: 

P. the countries members or the UNO have set up environmental protection agencies. They hold conferences discussing ecological problems, take practical measures to avoid  ecological disaster.

P. I’ve got a pen- friend in London. He wrote that in Britain    there  are a lot of environment groups . “ Friends of the Earth”,  “ Greenpeace”, “London wildlife Trust”,  they take part in environment activities.

P. In the USA there are many national parks Yellowstone is one of the most famous of them. Although millions of people visit the park, the land is still unchanged- still a wildness. The mountains around Yellowstone   are covered with

evergreen forests

.

Ec: Russia is cooperating in the fields of environment protection with the USA, Canada Norway and other countries. Russia and the US are carrying out joint projects to study  and protect the environmental system of the Arctic regions.

P. more then 30 years ago Aral was a bright blue sea with a lot of fish . But the cotton plantation the Aral is in a very dangerous position now. If no immediate measures are taken, the Aral Sea will disappear by the years 2015.

Speaking skills:

We have discussed global problems . Our small Motherland is the place we live in. can you add some words about our district?

What is the main eco problems of Karagandy?

P. The most  important of them is litter. It is everywhere People don’t put  the garbage can. In our town there are few litter cans and people throw the litter on the streets. That is why you can see of litter everywhere we can control it if people never throw litter themselves, and they work together in groups to clean up the town. The  schoolchildren can help to make our town cleaner.

Everyone shouldn’t leave litter on the streets  on the places of the rest and our town   will be cleaner .Many people of our town take an active  part in spring  cleaning. Schoolchildren help  them too.
