What will happen when the worlds water runs out?

Answer 1

There will be no human life

PLUS.. the world will never run out of water because water goes in a cycle

Water goes on a cycle, but when a land has no capacity to hold rainwater, or bring down the rain, it becomes difficult to get clean water. Deforestation and land/water pollution makes it difficult for the land to hold water.

There are many African countries where they have run out of water. Some rich European countries who has gone out of clean drinkable water just import water because they can afford it.

In underdeveloped countries who runs out of water, the economy automatically centres around water, because it is very important for life. People would even kill each other for some clean drinkable water.
