The Western US is running out of water.
It didn’t have much in the first place, of course: it was a founding concern of the region. Planners overcame the arid environment early on by engineering vast networks of reservoirs and aqueducts, ensuring that nary a drop of rain or snowfall runoff makes it into an ocean without first passing through a lettuce field or human body. By the time the Colorado River, the Southwest’s main source of fresh water, reaches the Mexican border and its last stretch before the Gulf of California, it’s not much more than sun-baked dirt.
