Americans care very little about water, because for most of our history water has been abundant and good. But problems with infrastructure and supply are growing.

Globally, the water crisis is much worse.

We are fast approaching a world in which the most hotly-contested resource for development and survival is not oil, but water.

This is also why investors have become crazy about it, pouring huge money into water rights, desalinization, and purification projects.
15 Facts About The Coming Water Crisis >


America must spend $255 billion in the next five years to prevent deterioration of water infrastructure. We plan to spend half that amount.



Parts of America use up to 80% of their available freshwater resources. (That means a slight drought or increase in usage will cause a WATER SHORTAGE.)

Transporting water is impractical, even within the U.S. Just look at the cost of bottled water.


A few exceptions to the economic limits on transporting water exist. Bottled water, for example, is sometimes consumed vast distances from where it was produced because it commands a premium far above normal costs. Growth in bottled water consumption may expand in some markets, but overall, long-distance transfers of bulk water are not likely to become a significant export in commercial markets.


Globally, 1.2 billion people live in areas with inadequate water supply.



1.6 billion live in areas where there is water, but they can't afford to drink it.



Water use is increasing much faster than population.



Global water demands will increase by 40% in the next ten years.



By 2025, two-thirds of the world will live under conditions of water scarcity.




Two-thirds of the cities in China suffer from water shortages. Clean water is even more rare.



India WILL run out of water in the near future.




"A shortage of water resources could spell increased conflicts in the future. Population growth will make the problem worse. So will climate change. As the global economy grows, so will its thirst. Many more conflicts lie just over the horizon." -- Ban Ki-Moon
