Why is our (US) government the only one in the civilized world with a stupid, short-term energy policy? Why do our elected officials consider a European or Japanese-type energy tax not only unpassable but undiscussable?

No one can define or measure justice, democracy, security, freedom, truth, or love. No one can define or measure any value. But if no one speaks up for them, if systems aren’t designed to produce them, if we don’t speak about them and point toward their presence or absence, they will cease to exist.

Biodiversity can't be maintained by protecting a few species in a zoo, or by preserving greenbelts or national parks. To function properly, nature needs more room than that. It can maintain itself, however, without human expense, without zookeepers, park rangers, foresters or gene banks. All it needs is to be left alone.

The actions of my government are not bearable. They devastate our natural resources and deprive our people. The politicians speak piously while practicing greed and divisiveness; they care nothing for the nation. I want to do more than withdraw my support. I want to tar and feather them.

We don't think a sustainable society need be stagnant, boring, uniform, or rigid. It need not be, and probably could not be, centrally controlled or authoritarian. It could be a world that has the time, the resources, and the will to correct its mistakes, to innovate, to preserve the fertility of its planetary ecosystems. It could focus on mindfully increasing quality of life rather than on mindlessly expanding material consumption and the physical capital stock.

The sustainability revolution will be organic. It will arise from the visions, insights, experiments and actions of billions of people. The burden of making it happen is not on the shoulders of any one person or group. No one will get the credit, but everyone can contribute.

Models can easily become so complex that they are impenetrable, unexaminable, and virtually unalterable.
