Is it too late to prevent us from self-destructing? No, for we have the capacity to design our own future, to take a lesson from living things around us and bring our values and actions in line with ecological necessity. But we must first realize that ecological and social and economic issues are all deeply intertwined. There can be no solution to one without a solution to the others.
 Jean-Michel Cousteau
