"Water is more important than gold"

- claimed the Bedouins.

And what we now know about water?

Have we reveal all its secrets?

People from far had been interested in studying it.

For many centuries, the people had no idea of what is the water, and how it was formed on the planet. Everyone knew that the formula of water is H2O. Harold Urey first discovered the molecules of heavy water in natural water in 1932. Water is always in contact with many substances in nature. Water is the major constituent of living matter. From 50 to 90 percent of the weight of living organisms is water. Says: there is no water - no life, there is water - there is life. The role of water is great for all living things. What would happen if the Earth would not have rivers, seas and oceans? In this case, life on our planet did not have the ability to even appear.  The problem of fresh water is that the world is constantly shrinking supplies of clean drinking water. The deficit of fresh water is also due to pollution of natural waters. Lake Baikal - lake in the south of Eastern Siberia, the deepest lake of the Earth's largest natural reservoir of fresh water. The future of Lake Baikal and people living

in this area depends on us.It is necessary to rescue Baikal.

Our native city is situated on the longest river in Europe. It is filled with poison industrial and nuclear waste, chemical fertilizers and pesticides. The Volga is already nearly dead. If nothing is done about it, one day nothing will be able to live in the Volga.

 That is why now in the first place should raise the question of how out of "dead" water to make a "live" drinking water, which would give humanity and the physical and moral health, as well as creative longevity.

I want people to treat the water with good things, with love, not to spit in the water and do not clutter them, do not have urinated in the water for bathing, no foul language at her. This will benefit both the person and the whole of nature. After the water - a gift from God, it is life itself! You just need to use it properly for its recovery.
