In California's central valley where 1/12 of the country's agriculture is grown, Discover Magazine reports that over the past 6 years, the loss of ground water in two of the main central valley's basins totalled 30 cubic kilometers. Does this sound like a small amount? Well, one cubic kilo equals 264 billion gallons of water so if you multiply by 30 you get a very scary picture with numbers only seen in our national debt.
So, the reason for this is that we are using drinking water and water for irrigation faster than it can be recharged. This comes from a study conducted by NASA and California researchers.
These researchers say that they do not know how much water is left but do know that a declining level causes a loss in water quality, decreased crop sizes, and land sinking. I observe that decreased crop sizes and lower levels will increase water prices and veggies in the markets.
Conclusion: Yo, Governor, Yo, U.S.D.A., where art thou?
