The climate continues to deteriorate.

Since the Earth is finite, and we will have to stop expanding sometime, should we do it before or after nature's diversity is gone?

There is too much bad news to justify complacency. There is too much good news to justify despair.

We can't control systems or figure them out. But we can dance with them!

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

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.

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.
