It also mentions Phoenix being the least sustainable city in the world and how many resources it takes to keep the desert at bay .
Re. that. If I were dictator of the U.S., I would require every single American to read
Cadillac Desert by Marc Reisner. The most astonishing non-fiction book I've read in these last twenty to thirty years. Basically, it explains in irrefutable terms how America west of the western border of North Dakota, South Dakota, Nebraska, Kansas, Oklahoma etc. is possible. That is, how it became inhabitable, or rather was made inhabitable to millions of people in the twentieth century west of that line, thanks to the biggest dam building and water diversion programme the world has ever seen, and billions of Federal dollars. He goes into the politics of it in Washington, the technical aspects, which are jaw-dropping, overseen essentially by the Army Corps of Engineers, the way native Americans were ridden over roughshod, and of course, the building of the biggest cities west of that line: Denver, the Bay Area conglomerate and Los Angeles. Which all exist courtesy of one thing: water. A truly incredible read, very well written.
Every American, whether they live east or west of that line, should read it. And just anyone who is interested in how mightily man can manipulate the environment when he's got the sheer manpower, engineering know-how, ruthlessness about the rights of indigenous populations, and dollar muscle, to back it up.
