The Old Testament contains in many places, but especially in the book of Job, one of the most far-reaching defenses ever written of wilderness, of nature free from the hand of man. The argument gets at the heart of what the loss of nature will mean to us....God seems to be insisting that we are not the center of the universe, that he is quite happy if it rains where there are no people - that God is quite happy with places where there are no people, a radical departure from our most ingrained notions.

I think we need to think of lots of ways to communicate. And we tried some at 350. We organised what they called the largest art project in the planet's history. We do a lot with art and music and things.

The roof of my house is covered in solar panels. When Im home, Im a pretty green fellow.
