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.
When God created the first man he took him and led him round all the trees of the Garden of Eden and said to him: look at my works, how beautiful they are! Take care that you do not corrupt and destroy my 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 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 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 smoke 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, fishes, mammals.
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.
