Water scarcity involves water stress, water shortage or deficits, and water crisis. The concept of water stress is relatively new. Water stress is the difficulty of obtaining sources of fresh water for use, because of depleting resources. A water crisis is a situation where the available potable, unpolluted water within a region is less than that region's demand.
The earth has 326,000,000,000,000,000,000 gallons of water. With 7 billion people, the earth has 46 billion gallons of water per person. This water is infinitely recyclable. Israel is now desalinizing water at a cost of US$0.53 per cubic meter. Singapore is desalinizing water for US$0.49 per cubic meter. After being desalinized at Jubail, Saudi Arabia, water is pumped 200 miles (320 km) inland though a pipeline to the capital city of Riyadh. According to MSNBC, a report by Lux Research estimated that the worldwide desalinated water supply will triple between 2008 and 2020.

Let me hide myself in Thee!
Let the Water and the Blood,
From thy riven Side which flow’d,
Be of sin the double cure;
Cleanse me from its guilt and pow’r.”
