We reached the old wolf in time to watch a fierce green fire dying in her eyes. … I thought that because fewer wolves meant more deer, that no wolves would mean hunter's paradise. But after seeing the green fire die, I sensed that neither the wolf nor the mountain agreed with such a view.
Aldo Leopold, A Sand County Almanac
