Eli5 why do we run out of water?

Question

I know we need to conserve water and such but why? Doesn’t it eventually flow back into the ground or evaporated and rained back down regardless of how it’s consumed, so it’s a cycle? Do we lose a bit per cycle?

Answer 1

it’s Clean water we will run out of. Any manufacturing plant is dumping process water into a source of drinking water.
