The modern southwest is a huge environmentally destructive science experiment, made possible only by heroic Army Corps of Engineers projects. We should slowly phase it out. Plenty of space back here on the east coast and Midwest.
Marc Reisner's book _Cadillac Desert: The American West and its Disappearing Water_, written in 1987 (a third of a century ago), documents part of this experiment, including actions of Los Angeles to get water, and the rivalry between the Bureau of Reclamation and the Army Corps of Engineers, among others.
