Question

if there is no water what will be done? ​

Answer 1

Water, is the most important need of humans. As, we know that 70% of human body consists of water. In, the case there will be no water then the following things can happen,
1)Humans will survive for few days and thereafter they will die.
2)All trees and other animals will also die.
3)Or the scientist will have to make some alternative for water.

Answer 2

Without water there would be no life on earth. The weather on earth is driven by the cycle of evaporating water, so without it there would be no rain, no rivers and none of the erosion caused by water.

It goes without saying that the human race wouldn't last very long in a world without water.

Every living thing on earth would die, since water is a large component of all known living cells, every plant, animal, fungus, etc would all dessicate completely, and crumble to dust. With all water vapor gone from the atmosphere, the sky might change color, and become a reddish tint due to the high oxygen content.
