An interesting piece from National Geographic:
Grabbing Water From Future Generations - Water Grabbers - National GeographicMany of the world's aquifers are being pumped dry to support unsustainable agriculture. ...
This is very true and has been going on overall since the 50's, and in some places for 100 years. Further more, there is no way to re-generate the acquifers. But we can make a lot more use of water reclamation and salt-water purification.
The difference in attitudes between the US east and west coast on water use is a bit funny. On the east coast they want to use as little water as possible. On the west coast they want not a drop to be wasted (to pass by unused).
We live inland on a larger river that flows to the ocean. By the time it gets to the Pacific it has been through at least 3 bladders, maybe 5.
Of course, the US has many times more people than our land can support.
