It has become apparent that the wanton exploitation of the earth might involve undesirable costs and might offer possibilities we would not like to imagine. Growth for growth's sake has come to be questioned, and even recog- nized by some as the philosophy of a cancer cell. Further, growth of income for some at the exclusion, and possibly at the expense, of others, the untoward gobbling-up 1Some would go further, and consider growth not just desirable, but essential. On the other hand, see William Woodruff, Impact of Western Man (New York: St. Martin's Press, 1967), p. xv: "I suspect that economic growth--like so many other aspects of our work that have managed to claim a disproportionate part of our time in the past--is receiving more attention than its true importance warrants.
