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 are all filled with a longing for the wild. There are few culturally sanctioned antidotes for this yearning. We were taught to feel shame for such a desire. We grew our hair long and used it to hide our feelings. But the shadow of Wild Woman still lurks behind us during our days and in our nights. No matter where we are, the shadow that trots behind us is definitely four-footed.

I swam across the rocks and compared myself favorably with the sars. To swim fishlike, horizontally, was the logical method in a medium eight hundred times denser than air. To halt and hang attached to nothing, no lines or air pipe to the surface, was a dream. At night I had often had visions of flying by extending my arms as wings. Now I flew without wings.

But nobody pointed out that the web itself is a miracle." "What's miraculous about a spider's web?" said Mrs. Arable. "I don't see why you say a web is a miracle-it's just a web." "Ever try to spin one?" asked Dr. Dorian.

We have a responsibility to protect the rights of generations, of all species, that cannot speak for themselves today. The global challenge of climate change requires that we ask no less of our leaders, or ourselves.
