Give some examples of human use of water.

Man uses water for different purposes.
1. For construction. Try stirring cement without water and building a house with it. You won’t succeed.
2. For life. It is unrealistic to live without liquid. It nourishes the cells and makes them viable. If you do not drink for one day, health problems may occur: impaired coordination, loss of vision, fainting.
3. To generate energy. Hydroelectric power plants have every chance to become the main source of alternative energy, because the reserves of minerals will sooner or later be exhausted.
