Global warming, for instance, which remains speculative and based on incomplete computer models rather than on demonstrated science, might cost man and nature a great deal if we rush to impose dramatic limits on fossil-fuel use in a misguided attempt to solve a problem that may not even exist. Just twenty-five years ago, some of the current proponents of global warming were warning us about global cooling.33 Because ecology is still in its infancy, we need to utilize all that we know to help us find prudent solutions for these complex problems. We must also recognize that science alone is insufficient for resolving these matters, especially since these issues have moral implications. Thus, in recognizing that we will have to make unavoidable tradeoffs in striking a balance between human need and a clean environment, we must exercise prudence in addressing environmental concerns.
