We humans use the most water at the fastest rate in the world. Humans are using up water much much faster than the water is formed deep below rock layers again resulting in rapid depletion of fresh water. At this rate the fresh water supply from underground sources might vanish.
because then there would be too much water use.
Humans use water to dispose of exess heat by sweating.
