There is little doubt in my mind that drinkable fresh water will be the most valuable thing in the world eventually. You cannot drink crude oil, gold, silver, platinum or diamonds. Desalination that is cost effective might save humanity, eventually. It is hard to imagine a world where everything we take for granted, have taken for granted for every minute of our lives, is just not there for us any more. As crazy as the world seems right now, we are living in the best of times. We should all work harder at enjoying it and keeping it this way.
