"We sees a world of abundance, not limits. In the midst of a great deal of talk about reducing the human ecological foot-print, 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?"
