In the light of global warming and rising sea levels it would seem like we have to much water. Yet there are arid areas on this planet and the topic of water security is becoming hot in governments. I found a book on water security from the United States Navy Postgraduate School at a used book sale. Scary stuff. For a fact sheet(PDF) go to United States Geological Survey. The water wars are real. The United States military is thinking about water. Should we be? Note: I am not the author of these publications. Just someone who lives in an arid area with water rationing." Link to Original Source
