“What do we do with this worthless area, the region of savages and wild beasts, of shifting sands and whirlwinds of dust, of cactus and prairie dogs? To what use could we ever hope to put these great deserts and these endless mountain ranges?”
– U.S. Secretary of State Daniel Webster, on the American West, 1852
The drought, if somewhat ameliorated by a passably wet winter in Northern California, reminds us that aridity defines the West. Our vulnerability is particularly marked here in Southern California, where the local rivers and springs could barely support a few hundred thousand residents, as opposed to the 20 million or so who live here. Bay Area, we’re talking about you, too, since about two-thirds of your drinking water is imported.
