We need to revise our economic thinking to give full value to our natural resources. This revised economics will stabilize both the theory and the practice of free-market capitalism. It will provide business and public policy with a powerful new tool for economic development, profitability, and the promotion of the public good.

Good management is the art of making problems so interesting and their solutions so constructive that everyone wants to get to work and deal with them.

It is possible for the assembly-line worker consigned to tightening the bolts on the transmission and the office worker who processes medical insurance claims to work with pride and efficiency, but it's not easy to maintain that attitude.

Sustainability, ensuring the future of life on Earth, is an infinite game, the endless expression of generosity on behalf of all.

When cattle ranchers clear rain forests to raise beef to sell to fast-food chains that make hamburgers to sell to Americans, who have the highest rate of heart disease in the world (and spend the most money per GNP on health care), we can say easily that business is no longer developing the world. We have become its predator.

We're trained to see the world in terms of charismatic organizations and charismatic people. That's who we look to for leadership and change, for transformation. We're awaiting the next J.F.K., the next Martin Luther King, the next Gandhi, the next Nelson Mandela.

Hindered by asthma since I was six weeks old, I had begun experimenting with my diet and discovered a disquieting correlation. When I stopped eating the normal American diet of sugar, fats, alcohol, chemicals, and additives, I felt better. I could breathe freely. When I tried to sneak in a hamburger and a Coke, my body rebelled.

All is connected... no one thing can change by itself.

The responses that environmentalists evoke - fear, anxiety, numbness, despair - are not helpful, even if they are understandable. It should be fascinating, even enthralling, to be in the milieu of environmental change.

I think an old style of addressing environmental problems is ebbing, but the rise of the so-called conservative, political movement in this country is not a trend towards the future but a reaction to this very broad shift that we are undergoing.

We are now heading down a centuries-long path toward increasing the productivity of our natural capital - the resource systems upon which we depend to live - instead of our human capital.

We assume that everything's becoming more efficient, and in an immediate sense that's true; our lives are better in many ways. But that improvement has been gained through a massively inefficient use of natural resources.
