There is a big ol' difference between "the planet can't sustain us!" and "What idiot thinks California and Nevada as such are sustainable?" People yammer about the true cost of energy being hidden when it comes to carbon footprints. I can get behind the logic. But considering that water in the US is pretty certain to become a problem significantly faster than man made climate change is going to and is far more solvable(if still extremely unpleasant), why am I not hearing the deafening roar of the hidden costs of our western desert-dwelling population and industry, much less the eating of fruits and veggies grown under irrigation in those climates, and in Florida, and the grains from the Ogallala? Guh, growing food in the deserts. Yammering about the necessity of local foods while planting millions of people in southern California. It's not a total failure of planning, but it's pretty bad.
