America has been overusing water for decades to the point that many of its aquifers are significantly depleted.
Yes.
Just, yes. I live in a state that is mostly desert, but also contains a strangely large lake. The problem is that the lake is drying up. It's only about half the size it was ten years ago, and is projected to dry up entirely in perhaps five years unless water policy here radically changes. Dry lakebeds are not an uncommon feature in the American Southwest, but this one happens to share a valley with 1.2 million people. When lakes dry up, all the heavy metals and other minerals they have accumulated over tens of thousands of years become airborne.
And that's entirely tangential to the main problem that 1.2 million people need something to drink. We've been in an ongoing drought for decades, and other aspects of climate change have prevented developed our seasonal snowpacks in the mountains. (As I sit here now and write this, New Orleans has received half again as much snowfall as we have this season so far.) The problem with the lake is that we're diverting more and more of its supply for use. The more showers we take and the more we water our lush, green lawns, the less ends up in the lake.
And to make matters even worse, a
huge amount of our domestic water supply is allocated to growing alfalfa. Fine, growing crops is a reasonable thing to do with lots of land. But alfalfa is a very water-hungry crop. Deciding to grow
that crop in a desert makes you stop and think. "But it's a useful crop," they say. "You can feed it to livestock." And that argument would matter if that's what's happening. Almost all our alfalfa is exported, mostly to China. This is a
cash crop. The relatively few number of farmers who do this (including our governor) are turning a disproportionate share of our scarce water into money into their pockets and no one else's.
As you can imagine, the solutions proposed for our drying-up state have not emphasized using less water. We have to keep that unwise crop growing, apparently, and watering our dozens upon dozens of golf courses. The most popular solutions involve elaborate plans to pump water from faraway places to replenish the Great Salt Lake. Apparently you can't tell some Americans that they're using too much of something and that no, there won't always just be more.
