Water is a some thing the world will need forever. Sustainable use of water is key for the future. I have been doing lots of reading and research on the change of use of the water. It has always been that 80% of the water in the US has been for agriculture. The issue become what is needed to be produce that is water intensive. An example of this is the tar sands in Canada it would only be possible to get the oil for it with out water. The logic of using something as important as water on extracting oil. The documentary liquid assets hit a lot of important points http://www.youtube.com/watch?v=bu0S3tp66Rg&feature=channel . There is nothing to switch to when there is no more water. People all over the world have been looking to water as an income source but finding that no amount of water in the world can be equal to a water supply. With more and more people going with out water it will be interesting to see what will be the optimum path to a global solution. If it will be government policy or capitalistic market policy, only time will tell.
