What are we going to do once all the water is gone? Thanks to the worst drought in more than 1,000 years, the western third of the country is facing the greatest water crisis that the United States has ever seen. Lake Mead is now the lowest that it has ever been since the Hoover Dam was finished in the 1930s, mandatory water restrictions have already been implemented in the state of California, and there are already widespread reports of people stealing water in some of the worst hit areas. But this is just the beginning. Right now, in a desperate attempt to maintain somewhat “normal” levels of activity, water is being pumped out of the ground in the western half of the nation at an absolutely staggering pace. Once that irreplaceable groundwater is gone, that is when the real crisis will begin. If this multi-year drought stretches on and becomes the “megadrought” that a lot of scientists are now warning about, life as we know it in much of the country is going to be fundamentally transformed and millions of Americans may be forced to find somewhere else to live.
