"the distinguishing feature of man's activities is that they have almost always been undertaken from the narrow viewpoint of short-range gain, without considering either their impact on the earth or their long-range effect upon ourselves. They have been distinguished, also, by a curious unwillingness to be guided by the knowledge that is available in certain areas of science. I mean especially the knowledge of biologists, of ecologists, of geneticists, all of whom have special areas of competence that should allow them to predict the effect of our actions on living creatures, including, of course, man himself."
