nature and about relation of man with it.
Practically, it

is a science studying whether we, human being, keep our common house, our planet Earth, in a good state and how we use the gifts it is giving us: water, air, land, plants, animals and minerals.
Ecology is a science which studies the relationship between all forms of life on our planet with its environment.

of today?
Air pollution, smog, water pollution, destruction of

natural resources.

The ozone layer in the upper atmosphere protects the world from the sun’s harmful rays. The chemical used widely in aerosol cans, refrigerators, and other products are destroying this precious layer.

The electric power station burn coal to produce the energy that keeps our light on. That burning coal gives off gas that came the greenhouse effect (парниковый эффект) and acid rains (кислотные дожди).

worried about the Earth, some ecological problems appear:
Air

and water are polluted
Forests are cut down
Animals are damaged
Wildlife is disturbed
Litter is put into water
Health is spoiled

animals, birds, fish and people. But what’s happening now?





Air
Water
Land
A lot

of rivers and lakes are polluted
Sea animals are hurt

Air pollution is not reduced

Global warming is caused by the greenhouse effect

The forests are cut down
When the forests disappear many animals are disturbed
Most of the countryside is spoiled

THE ENVIRONMENT?
We pollute the air. – We change the

climate.
We leave a fire. – We destroyed the forest.
We throw away plastic bottles. – We damage nature.
We leave litter in the forests. – We hurt animals.
We break trees. – We disturb birds.
We don’t recycle paper. – We cut down trees to make new paper.
We throw litter in the rivers and seas. – We cause water pollution.

the environment at school. All of them remember the three

R’s:

What can or must we
reduce?
(уменьшать)
reuse?
(использовать заново)
recycle?
(перерабатывать)

We can reduce using electricity.
We can reduce using water.
We must recycle cartons.
We must reuse glass bottles.
We can recycle newspapers.
We must recycle paper.
We can recycle plastic containers.

All these actions help to reduce pollution, deforestation and not to damage the nature.

“
Do you agree with this statement?

Why? Why not? Give your examples.

This is teen’s opinion:
I agree with this statement “to hurt the Earth is to hurt yourself” because the Earth is our home. Everything is connected. When we pollute air and water we spoil the things we use because we breath this air and drink this water. If the balance in nature is destroyed we will die too.

There are over 300 nature centres in British cities.

There are a lot of environment groups: Friends of the Earth, Greenpeace and others.

than the place we call home. The Earth is

our environment. It means that the land, air, water and wildlife that surround us affect the way we live. And the way we live affects the natural world outside our front door. A lot of people understand this and see urgent environmental problems. 52% think that water pollution is a problem. 43% think that when trees are cut down it is a problem. Air pollution is a problem for 32%.

of people think about the future of the planet.

Some people take care of animals, others take care of birds, others are in charge of forests.

I think children can help the planet. They can recycle. They can plant trees and help animals. If they don’t leave litter and don’t damage wildlife the nature is not spoiled.
It is important that children should take part in saving Earth.
We are in charge of the planet because we all pollute it and I think that we all should try to help it.

Planet!

a serious problem. It effect everyone every day. Where

does the pollution come from? Is it only factories, big ships and cars that pollute? No, it is you and me as well. If you drop litter, you pollute. That's how it begins. What happens when millions of people do the same thing?
    Most big cities pour their waste into seas and rivers. The first alarm came from Japan. Some sixty people died as they had eaten polluted fish.
       The Baltic is a special case. Because it is such a small sea it becomes dirty very easily. Its water changes slowly. As many as 250 rivers run into the Baltic. There are hundreds of factories on these rivers and millions of people live along them. Seven industrial countries surround the Baltic. A lot of big cities lie on its coast. All of this combined with the active navigation of the affects the state of the sea water and the shore line flora and fauna.    
        It is difficult to clean it now. Fortunately all the countries in the Baltic area have realized the problem. They cooperate in solving ecological problems of the Baltic basin. The aim of the agreements is to prevent pollution of the sea and to preserve sea life.
