We had a brief talk with an old friend about the coming shortage of clean water in the developing world and industrialized world and what the impact will be on energy, money, and classes. So when I saw the caption to the Water Is Life photo set at National Geographic, I stopped to think.
From Nat Geo:
The amount of moisture on Earth has not changed. The water the dinosaurs drank millions of years ago is the same water that falls as rain today. But will there be enough for a more crowded world?
