Man and hydrosphere

For all kinds of irrigate - industrial and internal on the globe is taken from rivers irrevocably about one hundred fifty cubic km pissing per year. Its solitary(prenominal) if 1 % of the resources flow. irrigate is used alike for producing former(a) things unavoidable for the soul : products (sugar , wh feed, rice, etcetera ) , clothing (synthetic fibers). It would depend no cerebrate to fear the peeing famine , which very much brace to joint lately. But new urine organization fraught with the peril of depletion of piddle resources.\nThe terror of a piddle system crisis is not so much the submit of piss to look all needfully , as the master(prenominal) sources of pollution in the water supply system, especially the river and lake irrigate in roughly areas of our planet.\nIn youthful years, more an violence of water pollution problem . ill substances into rivers and lakes with melted light speed and rain water flowing from the city and from the fields (also a great invasion on water pollution have owned factories plunk their waste in the water) . Contaminated water is dead - mentally ill for drinking and kinsfolk use . In her sick and expiry fish and other aquatic inhabitants . In the water with an teemingness of phosphorus and newton begins a speedy development of certain(a) bacteria or plants , such as blue-green alga . They say that water blooms . This is not a harmless point , because as a result it dramatically reduces the oxygen capacity and suffers about aquatic organisms. Drink water or eat fish from water bodies such person is strictly prohibited.\n enigma can be solved with the attend to of special preaching facilities of various types. The most promising biological treatment, however, and it is 20% water contaminated . Therefore, scientists implement a focus not only to improve treatment systems , but in a understructure change in the production itself : he will campaign to less water and even arid , and most significantly , environmentally exit technology . in any case to effectively storm the depletion of water resources need to stop cast out sewage into rivers and reservoirs .
