Will All the Water on the Earth Be Used Up?

If we don't drink water, we will die of thirst. Without water, there will be no life on the earth. We use water everyday. But will the water be used up one day? No. There is a lot of water on the earth. Everyday, part of the water from the ground and sea becomes steam and goes up into the sky and turns into clouds. Then clouds become rain or snow and fall onto the ground. This is how water circulates.

But in places where there are many people and not enough water, and in places where there are droughts or where there are factories that use a lot of water everyday, there is a shortage.
