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.

Being a good human being is good business.

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.

What we already know frames what we see, and what we see frames what we understand.

While there may be no "right" way to value a forest or a river, there is a wrong way, which is to give it no value at all. How do we decide the value of a 700-year-old tree? We need only to ask how much it would cost to make a new one, or a new river, or even a new atmosphere.

Being in business is not about making money. It is a way to become who you are.
