I think what he was getting at, is that people like to pretend that Arizona is on track to be uninhabitable in 2 years. It's like I said before, people being dramatic about the issues facing places they don't live or visit regularly. The Phoenix valley was just as much a desert when it first was settled as it is now, and the arid desert conditions and droughts are planned for and designed around. I completely agree with you that it COULD reach a breaking point one day, but that's not anytime soon or something that people need to be concerned about at the moment. I personally think we should all be aware of our water usage, but am I worried about having to mass exodus out of Phoenix in 2023 because of water shortages? Not at all.Also, a poor understanding of ecology. Arid climates aren't meant to support millions of people. Engineering can make it happen, but the harder you lean on that engineering, the closer to the precipice you get.
