It is known, that about 70 percent of the Earth's surface is water-covered, but water is mostly salt. Only 2.5% of Earth's water is freshwater. Almost all of it is locked up in ice and glaciers.
The planet's fresh water is very unevenly distributed: the vast majority of the population lives in predominantly arid parts of the planet. In fact, the shortage of fresh water has effects on 40% of people in the world.
By the middle of the ХXI century, the number of people living with a constant lack of water could reach 4 billion people, because the Earth's freshwater reserves do not increase, and its consumption is constantly growing.

In Baikal alone, 20% of the world's freshwater reserves are contained.
