Question

Is there a finite amount of water on Earth, in any form, and could we ever run out?

In: Chemistry

Answer 1

Yes, there is a finite amount of water, but there is a lot of it and it’s doubtful we would “run out”.

The 2 challenges are the amount of fresh water, and getting fresh water to the right places.

This is why we really need to develop technology for cheap water desalination/water purification and to improve our water distribution systems. If we had the ability to cheaply irrigate more of the earth using desalinated ocean water, it would be a game changer for humanity.
