The Southwest, to some extent, has mistaken the drought cycle we’re in as being climate change. People have talked about this up and down but the fact remains that the big cities of the Southwest exist only because water could be moved to them. All the mega-cities of the Southwest—Los Angeles, Las Vegas, Phoenix—are sitting smack dab in the middle of deserts and only exist because water could be moved to them. That’s how they grew and the only reason they could grow. So, guess what’s going to happen if that water isn’t available? Right. Shake hands with the Anasazi.
