Water Shortages

ĄBetween 1950 and 2000, world water use tripled

ĄSome 70% of water use is for irrigation

ĄOverextraction is leading to disappearing lakes and rivers failing to reach the sea

ĄAquifer depletion is causing water tables to fall and wells to go dry

Ą175 million Indians, 130 million Chinese are fed with grain produced by overpumping

Since the overpumping of aquifers is occurring in many countries more or less simultaneously, the depletion of aquifers and the resulting harvest cutbacks could come at roughly the same time, creating potentially unmanageable food scarcity.
