'All past civilizations have gone through similar patterns of over-growth and decline. But ours is the first global, fossil-fueled civilization and its collapse will therefore correspondingly be more devastating. The basic outlines of the crisis were traced over 40 years ago in a book titled The Limits to Growth. Today we are hitting the limits of net energy, environmental pollution and debt .We have overshot human population levels that are supportable long-term. Yet we have come to rely on continual expansion of population and consumption in order to generate economic growth — which we see as the solution to all problems. Our medicine is our poison. All of this constitutes a fairly simple and obvious truth. But evidently our leaders believe that most people simply can’t handle this truth. Either that or our leaders are, themselves, clueless.'
