“Carrying out the Great Work of making an ecologically durable and decent society will require us to confront the deeper cultural roots of our problems and grow out of the faith that we can meet the challenge of sustainability without really changing much. The evidence, I think, shows that we will have to change a great deal and mostly in ways that we will come to regard as vastly better than what exists now and certainly better than what is in prospect.”
