Importance of water for our planet
Water is an amazing liquid, it has no color, no taste, no smell. Caloric content of water is zero. Some people call it a real mystery. Water combines both simplicity and complexity at the same time.
There are only three atoms in a water molecule - one oxygen and two hydrogens. However, scientists are still not clear about the nature of these molecules and their collective activity. But one thing is certain: there will be no life on Earth without water.
The importance of water to human life is hard to overestimate. Without water, neither people, nor plants, nor animals could survive. Neither a huge elephant nor microscopic bacteria can survive without this life-giving liquid.
Every living organism consists of about 80% of water. Without it, the crop will not grow in the fields, and accordingly - there will be no food. So, it is entirely clear: without water, the life on our planet would disappear.
