California is leading the West into the big drought;
"In the United States, our population has doubled since 1950 while our water use has tripled. Today, over 50 percent of our country is grappling with drought. Pressure is particularly mounting on arid western states, with California on the frontlines."
"According to Jay Famiglietti, NASA's senior water scientist, California is, in no uncertain terms, running out of water. "Right now the state has only about one year of water supply left in its reservoirs, and our strategic backup supply, groundwater, is rapidly disappearing," said Famiglietti. "We're not just up a creek without a paddle in California, we're losing the creek too.""
Without sustainable use and acknowledgement of the limits on our water supplies, California may be the canary in the coal mine, an example of what not to do.
