I think that everything in

the world must be beautiful.

A human life is a part of

the whole environment and closely

connected with it. It is true.

If a nature exists, then a man will

live too.

But what are we doing? Just look!

Littering

Air pollution

Water pollution

Endangered species

Destruction of natural resources

There are different resources that we need as air. But there is no resource as the air itself. We can feel its absence lack in less than in a minute. It is known that pollution of atmosphere is caused by the work of factories, plants, cars etc. Here are the results of human activity!

1

Carbon dioxide

2

3

It is formed from the combustion of all kinds of fuel. The increase of its existence in atmosphere leads to increase of its temperature. This is the way how we have ecological consequences.

Carbon monoxide

Sulphur dioxide

4

It is formed from the incomplete combustion of fuel. It can break the thermal balance of atmosphere.

It is in smoke of the industrial enterprises.

Nitric oxides

5

It causes respiratory diseases and a bronchitis in newborns. Smog is formed with them and caused respiratory diseases.

Phosphates

6

There are many of them in fertilizers. They pollute rivers and lakes.

Mercury

7

It is one of the most dangerous polluter. It harmfully operates on our nervous system

Oil

It leads to the great ecological consequences: destruction of organisms, fishes, mammals.

Look how beautiful can be our planet!!!

Please, be more merciful, be more kind,

There’s no boarder for the light.

There’s no boarder for the wind.

And for the birds that we need.

We have to save our planet

For those who will live after us.

But we use a lot of poisons

And don`t think about our house.

The ozone layer is becoming thinner

It is a shield of life on the Earth

Zones are growing quickly as evil

And there is hidden in the darkness death.

Forests leave their forces

The smell of lime-trees is going by

Keeping sulphate waters

Rains are falling from the sky.

(By Samogova A.K)

We must take care of it.

The importance of this is pointed out by the

ecologists, scientists, who study the relations

between living things and their environment.

Each of us must do everything possible to keep

the land, air and water clean.
