Of all the unexpected qualities of an unexpected universe, the sheer organizing power of animal and plant metabolism is one of the most remarkable. . . .

...if we want to meet the obligations of our civilization and our culture which are to create communities for our children that provide them with the same opportunities for dignity and enrichment as the communities that our parents gave us, we've got to start by protecting that infrastructure; the air that we breathe, the water that we drink, the landscapes that enrich us.
