The more we learn about the challenges of sustainability, the clearer it is that we are poised at the threshold of a historic moment in which many of the world's industries may be transformed. Rarely is greening linked to strategy or technology development, and as a result, most companies fail to recognize opportunities of potentially staggering proportions. It should be clear that transformation toward global sustainability will mean the creation of trillions of dollars in products, services, and technologies that barely exist today.

- Stuart Hart, Author of Capitalism at the Crossroads

The key is not to make industries smaller, as efficiency advocates propound, but to design them to get bigger and better in a way that replenishes, restores, and nourishes the rest of the world. Thus the "right things" for manufacturers and industrialists to do are those that lead to good growth - more niches, health, nourishment, diversity, intelligence, and abundance - for this generation of inhabitants on the planet and for generations to come.

There are noble fortunes to be made in the transition to sustainability.

- Ray Anderson, Chairman of Interface Corporation

In a single lifetime, the human population will have grown from two billion to more than eight billion. Never before in human history has a single generation witnessed such explosive change. It seems self-evident that the policies we adopt, the decisions we make, and the strategies we pursue over the next decade or two will determine the future of our species and the trajectory of the planet for the foreseeable future. That is an awesome responsibility, to say the least. It is also a huge opportunity.

- Stuart Hart, Author of Capitalism at the Crossroads

The illusion is mainly due to our inability to recognize that the modern industrial system, with all its intellectual sophistication, consumes the very basis on which it has been erected. To use the language of the economist, it lives on irreplaceable capital which it cheerfully treats as income.

- E.F. Schumacher, Author of Small is Beautiful

The time has come to lower our voices, to cease imposing our mechanistic patterns on the biological processes of the earth, to resist the impulse to control, to command, to force, to oppress and to begin quite humbly to follow the guidance of the larger community on which all life depends.

- Wendell Berry, Author of The Art of the Commonplace
