A Crisis in Water Supply Exists Everywhere

Every place on Earth has experienced a water supply crisis sometime in history. And the future is not expected to be any different - every place on Earth is expected to be hit with a crisis in water supply sometime in the future.


Drought
Drought is the worst form of water crisis. It is a term applied to locations that have experienced NO RAIN for an extended period of time.

Drought maps have been produced for the world, and no continent is immune from severe drought except the polar regions that are awash in water and ice, and where no large human presence exists and where no human activity is performed.

It needs to be recognized that even areas not highlighted to experience any drought will have "minor" crisis with their water supplies. For example, some may find their water temporarily polluted and unsafe to drink; others may experience a break in the aging infrastructure that will temporarily cut their supply; others may simply get no rain to replenish reservoirs and a temporary restriction may be imposed on water usage.


The water crisis exists all over the world, but with varying impact. And everywhere there exists (a) the atmosphere, that contains water in vapor and liquid form and (b) Wind that continues to deliver water-laden air everywhere.
