The Stone Age did not end because humans ran out of stones. It ended because it was time for a re-think about how we live.

Our concept of eco-effectiveness means working on the right things - on the right products and services and systems - instead of making the wrong things less bad. Once you are doing the right things, then doing them "right," with the help of efficiency among other tools, makes perfect sense.

I just think it is so delightful to see people, let their elbows free. I think the exuberance of it all is really exciting to me. It's a signal of the abundance of diversity and creative expression.

In the end, the question is not, how do we use nature to serve our interests? It's how can we use humans to serve nature's interest?'

And to use something as elegant as a tree? Imagine this design assignment: Design something that makes oxygen, sequesters carbon, fixes nitrogen, distills water, makes complex sugars and foods, changes colors with the seasons, and self-replicates. and then why don't we knock that down and write on it?

We see a world of abundance, not limits. In the midst of a great deal of talk about reducing the human ecological footprint, we offer a different vision. What if humans designed products and systems that celebrate an abundance of human creativity, culture, and productivity? That are so intelligent and safe, our species leaves an ecological footprint to delight in, not lament?
