as no on can produce water????????????????????

Answer 1

Water is a renewable resource.It is just that the stock would reduce.Anyways, I am sure that soon humans will discover a way to use sea water more efficiently.There is so much water in water bodies we cannot use at the moment.Considering the fact that mankind has made so much progress,I am sure we can use the water from oceans some day in the future.Also waste water is being recycled. There are facilities which clean the water.they just aren't very efficient.
However this does not mean that you can waste water now.The world is still facing a water crisis!

Answer 2

Naturally water can be regenerated by water cycle

And humans should follow rain water harvesting ,store water for future use
