I am a native of Phoenix. Live there for four decades. It drove me nuts, the rate at which they were building golf courses and encouraging people to move there. I watched as they tore out orchards and farm land and built housing and condos and turned the Valley of the Sun into a heat island. It used to be in the summer that yes, the day would get up to 110, 115f, but at night it would cool down to the mid 80s or so. The land breathed. Not anymore.

Now I can visit, but I couldn't live there. About 30 miles from the southern fringe I have to close my car's vents because of the air pollution. Just can't handle it anymore with my lungs and occasional hyperosmia.
