In the publication of young specialists of Krasnoperekopsky management of a water management the actual problem of protection of water objects (the rivers, lakes, the seas, ground waters etc.) from pollution, preservation of fresh water on Earth is lifted.
On MARCH 22 WATER-TRANSPORT WORKERS CELEBRATED the DAY
On March 22 the world community celebrated Day of water. Thawing its stocks force mankind to be anxious, and a science to look for ways of savings of reviver.
Signing the Decree About measures for development of irrigated agriculture in Ukraine the president of the country Victor Yushchenko provided measures which will promote his intensive development, rational and effective use of irrigation water.
The problem of water use is sharpest and for our droughty region. Therefore we also publish a selection in which materials the Crimean problems of water use and irrigated agriculture are opened.
Understanding that one newspaper performance situation not to correct, we plan this subject to continue.
Now the problem of pollution of water objects (the rivers, lakes, the seas, ground waters etc.) is most actual. After all all know that water – is life. Without water of people can’t live more than three days, but even understanding all importance of its role in its life, it all the same continues to maintain rigidly water objects, irrevocably changing their natural mode dumpings and a waste. Fabrics of live organisms for 70 % consist of it and consequently V.I.Vernadsky defined life as water of life. On its earth there is a lot of, but 97 % – are salty water of oceans and the seas, and only 3 % – fresh. Three quarters of fresh moisture are almost inaccessible to live organisms as these stocks "are preserved" in glaciers of mountains and polar caps (glaciers of the Arctic and Antarctic). It is a reserve. And available to live organisms, it is generally concluded in their fabrics
The need for water at organisms is very great. For example, for formation of 1 kg of a biomass of a tree it is spent it to 500 kg. And consequently it needs to be spent, instead of to pollute.
The bulk of water is concentrated at oceans. Water evaporating from their surface gives reviver to natural and artificial ecosystems of a land. The area is closer to the ocean, the more there drops out a precipitation. The land constantly returns water to the ocean, the part it evaporates, especially the woods, the part gathers the rivers in which rain and snow drains arrive. The exchange of moisture between the ocean and a land demands very large amount of energy: about 1/3 that the earth receives from the sun are spent for it.
The water cycle in the biosphere before development of a civilization was equilibrium, the ocean received from the rivers so much, how many was spent it at evaporation. If the climate didn’t change, not meleli the rivers and the water level in lakes didn’t decrease. With civilization development this cycle began to be broken, as a result of watering of crops evaporation from a land increased. The rivers of the southern areas shoaled, pollution of oceans and emergence reduced a quantity of water by its surfaces of an oil film, evaporated by the ocean. All this worsens biosphere water supply. Droughts become more frequent, there are centers of ecological disasters.
Besides, and fresh water which comes back to the ocean and other reservoirs from a land, is often polluted. Practically not for drink water of many rivers of Ukraine became suitable.
Before the inexhaustible resource – fresh pure water – becomes ischerpayemy. Today suitable for drink, industrial production and an irrigation, doesn’t suffice in many regions of the world.
It is necessary to do the utmost for preservation of fresh water on Earth.
