"Concomitant with the loss of knowledge as to who man is, is the abuse of his environment — now erroneously thought to be totally other than man himself. In the resulting dehumanization and desacralization of Nature, man experiences suffering in fear. For if men listen to no other teacher, Nature demands that they listen to it; inevitably, it is the Master who must and will have the last word. Approaches to ecological problems which ignore these fundamental concerns will always remain superficial, illusory, and ineffective."
