It is possible to point to hundreds, thousands, perhaps even millions of imaginative, courageous programs to reduce, recycle, and reuse - yet the overall trajectory of industrial civilization remains relatively unchanged.

Early ecologists soon realised that, since humans are organisms, ecology should include the study of the relationship between humans and the rest of the biosphere. ... We don't often tend to think about the social sciences (history, economics and politics) as subcategories of ecology. But since people are organisms, it is apparent that we must first understand the principles of ecology if we are to make sense of the events in the human world.

Economic growth as we have known it is over and done with.

The industrial civilisation is based on the consumption of energy resources that are inherently limited in quantity and that are about to become scarce. When they do, competition for what remains will trigger dramatic economic and geopolitical events; in the end, it may be impossible for even a single nation to sustain industrialism as we have know it in the twentieth century.

As political theorist Michael Parenti points out, historians often overlook Fascism's economic agenda--the partnership between Big Capital and Big Government--in their analysis of its authoritarian social program. Indeed, according to Bertram Gross in his startlingly prescient Friendly Fascism (1980), it is possible to achieve fascist goals within an ostensibly democratic society.

We are about to enter a new era in which, each year, less net energy will be available to humankind, regardless of our efforts or choices. The only significant choice we will have will be how we adjust to this new regime. That choice - not whether, but how to reduce energy usage and make a transition to renewable alternatives - will have profound ethical and political ramifications.

Today, it is especially difficult for most people to understand our perilous global energy situation precisely because it has never been more important to do so.
