Marston Bates:


Man, in gaining the godlike quality of awareness, has also acquired a godlike responsibility. The question of the nature of his relationships with the birds and the beasts, with the trees of the forests and the fish of the seas, become ethical questions: questions of what is good and right not only for man himself, but for the living world as a whole. In the words of Aldo Leopold, we need to develop an ecological conscience.
