In 1971 McHarg delivered a speech at the North American Wildlife and Natural Resources Conference in Portland, Oregon, called "Man: Planetary Disease". In the speech he asserted that, due to the views of man and nature that have infiltrated all of western culture, people are not guaranteed survival. Of man, McHarg said, "He treats the world as a storehouse existing for his delectation; he plunders, rapes, poisons, and kills this living system, the biosphere, in ignorance of its workings and its fundamental value." To this end man is a "planetary disease", who has lived with no regard for nature. He discusses how in the Judeo-Christian traditions, the Bible says that man is to have dominion over the earth. McHarg says that for man to survive, this idea must be taken as an allegory only, and not as literally true. Lest this statement be construed as anti-religion, he cites Paul Tillich (Protestantism), Gustav Weigel (Catholicism), and Abram Heschel (Judaism) as noted religious scholars who are also in agreement with him on this point.
