Холодный рассудок, горячее сердце - и Вы поймете, как нелегко нашей планете Земля...

"WHO ARE WE? THE FRIENDS OR THE ENEMIES OF THE PLANET?"
The term "ecology" emerged at the end of the twenties century as one of the most popular and most important aspect of biology. The word comes from Greek "oikos", meaning "household, home, or place to live". Thus ecology deals with the organism and its environment.
Interrelations between the humans and their environment causes a lot of problems nowadays. And the most urgent problem is an ecological one. Man like any other living organism depends on what Nature provides: water, oxygen, food and shelter. On the other hand all sorts of human activity make the environment unhealthy. The contradiction between man and Nature are dramatic. The main problems are: air pollution, water pollution, acid rains, safety of nuclear and hydraulic power station, radioactive and other poisonous materials, disposal of wastes and others.

Man appeared late in the history of the Earth. But he was able to change the environment of the Earth by his action. In ancient times Nature served Man, it was the source of his life. For thousand of years people lived in harmony with environment. They took things necessary for life only. They worshiped for Nature because they were afraid of its whims such as drought, fires of forests or unsuccessful hunting. All of this could lead to starvation.
But with the development of civilization man's interference in Nature began to increase. It seemed to him that natural riches became unlimited. Man considered that he was stronger than Nature and he didn't depend on it. He even decided to subjugate Nature with the help of technique. Large cities with thousand of smoky industrial enterprises appeared all over the world. The products of their activity polluted the air, the water, the ground. It lead to destruction of forests and to extinction of many animals, pieces of fish, birds, plants. The situation was serious.

Every year world industry pollutes the atmosphere with about one million tons of dust and other harmful substances. Pollution is hanging like a brown cloud over large cities. Dirt and smoke are pouring from cars and factories. Pollution is spoiling the air we breath, and it's harming our health. Many cities suffer from smog. They have dirty air. It smells bad and it looks ugly. Pollution is a health problem because it's hurting people's lungs.
