of it. Ever since the Apollo 8 astronauts photographed Earth from space in 1968, we’ve had the image of our home as a strikingly blue planet, a place of great water wealth. But of all the water on Earth, only about 2.5 percent is fresh— and two-thirds of that is locked up in glaciers and ice caps. Less than one hundredth of 1 percent of Earth’s water is fresh and available. Across the United States and around


C


the world, we’re already reaching or overshooting the limits of Earth’s natural replenishment of fresh water through the hydrologic cycle. The Colorado and Rio Grande rivers are now so over-tapped that they discharge little or no water into the sea for months at a time. According to the U.S. Geological Survey (USGS), the mas- sive Ogallala Aquifer, which spans parts of eight states, from southern South Dakota to northwest Texas, and provides 30 per- cent of the groundwater used for irrigation in the country, is steadily being depleted. In much of the world, we’re growing food


heap and seemingly abundant, water is so common that it’s hard to believe we could ever run out


and supplying water to communities by over-pumping groundwater. This creates a potential crisis in the food economy: We are meeting some of today’s food needs with tomorrow’s water.


The Changing


Climate Equation Due to climate change, we may no lon- ger be able to count on familiar patterns of rain and snow and river flow to refill our urban reservoirs, irrigate our farms and power our dams. While farmers in the Midwest were recovering from the spring flood of 2008 (in some areas, the second “100-year flood” in 15 years), farmers in California and Texas allowed cropland to lie fallow and sent cattle to early slaughter to cope with the drought of 2009.


In the Southeast, after 20 months of dryness, then-Georgia Governor Sonny Perdue stood outside the state capitol in November 2007 and led a prayer for rain. Two years later, he was pleading instead for federal aid, after intense rain- fall near Atlanta caused massive flooding that claimed eight lives. This year again


For at least three decades, Americans have talked about our uncertain energy future, but we’ve mostly ignored another worrisome crisis—water.
