One of the most perplexing concepts is that on a planet covered by 75% water, we could actually experience shortages. Of course, seawater is not drinkable, so desalination is required. In prior posts I've touched on the concept of resource shortages. The most common topic regarding shortages is oil. The "peak oil" concept continues to gain traction. From my observation, a shortage of water is an unknown concept to most......unless your a Californian. They are realizing that living in a desert is a long term losing battle against nature.

"The two "R's", religion and resources, will keep the Middle East on the front headlines. The "R's" will expand well beyond the Middle East before this is over."
