Two new studies show that current groundwater use has reached unsustainable levels, a “tipping point’ that threatens to undermine regional water security.
Despite recent rains in California, it's still going to take about 11 trillion gallons of water for the state to recover from its historic and ongoing drought. Shockingly, that's around 1.5 times the maximum volume of water in the U.S.'s largest reservoir.
It's now just as likely for an area of the U.S. to be in drought as not.
When we talk about a future of drought and water shortages, we're not just talking about the amount of water. We're also talking about how it's distributed — a feature that this world map of the per capita renewable water resources in each country illustrates nicely.
