Professor A. Hertzberg.
" We have a responsibility to life, to defend
it everywhere, not only against our own
sins, but also against those of others.
We are all passengers together in this
fragile and glorious world ".

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.

Look at our rivers and lakes . Look at our mountains and forests.
How beautiful they are! Take
care of our planet and do not destroy
our universe, for if you destroy it no one
will repair it after you!

There are different resources that we need as air. But there is no resource as the air itself. We can feel its absence 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
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.
2
Carbon monoxide
It is formed from the incomplete combustion of fuel. It can break the thermal balance of atmosphere.
3
Sulphur dioxide
It is in smokes of the industrial enterprises.
4
Nitric oxides
It causes respiratory diseases and a bronchitis in newborns. Smog is formed with them and caused respiratory diseases.
5
Phosphates
There are many of them in fertilizers. They pollute rivers and lakes.
6
Mercury
It is one of the most dangerous polluter. It harmfully operates on our nervous system.
7
Oil
It leads to the great ecological consequences: destruction of organisms, fish, mammals.
The results of human activity

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
And it's 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.

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, the air and the water clean.
The Earth is our home
