Man can not exist without nature separately. Globe is a home for man. Here, it has all the necessities of life; air, water, food. But unfortunately, people often forget about it, and refers to his planet like strike, it destroys the surrounding nature, oblivious to the fact that she gives him life. Why cut the branch on which you sit?
Previously, people thought that natural resources are inexhaustible and can be taken on the nature of all, at the same time in large numbers. But it turned out all wrong. Nobody thought about how you can take so much, with it without giving anything in return? Oh no, in return of course, nature has received piles of garbage, toxic emissions into the atmosphere, soil, water.
