Speaking of disequilibrium, this is almost the same question that is plaguing the American Southwest regarding water. Is there a point that Las Vegas becomes unlivable? Is it when the lake runs dry? Is it when water has to be pipelined from desalination plants? Is it when water costs more than oil? In my opinion there is a fail point here; however, many in the 1% do not believe it’s will happen. The perpetual growth train is still on the tracks and steaming away.
