We all know that water is the source of life. All life on earth in the most part consists of water. And even this king of nature, somewhere in the 60-70% water. But, the problem is that people often forget. Often just ordinary people relaxing on the nature of the river, on the lake, throw garbage directly into the water. Will tell — anything? Well, go ahead. Factories discharged into their waste water, polluting them and killing all life. Because treatment facilities were cheap, much easier to bring the pipe into the lake or river. And frequent accident of oil tankers? Pouring over the surface of the sea, of the ocean, it kills fish and birds. And bring out these oil slick is very difficult. Yes, we humans are rational beings. But sometimes we forget about it, and act like the barbarians who came from another planet
