Environmental pollution is the most actual problem of the present since anthropogenous activity affects all terrestrial spheres: atmosphere, hydrosphere and lithosphere. Thus, the person, being the main responsible for the developed ecological situation, falls also its main victim: according to some information, from pollution of water resources, atmospheric air and a soil cover in the world about 40% of people perish. The main environmental problems of the present among which climate change, exhaustion of an ozone layer, desertification, decrease in biological diversity, pollution of waters of the World Ocean have no frontiers and have to be solved all world community.
