Aarne Naess, in a seminal paper on environmental philosophy, distinguished between two streams of environmental philosophy and activism—shallow and deep. The deep, long-range ecology movement has developed over the past four decades on a variety of fronts. However, in the context of global conferences on development, population, and environment held during the 1990s, even shallow environmentalism seems to have less priority than demands for worldwide economic growth based on trade liberalization and a free market global economy.

: Recently a number of influential academic environmentalists have spoken out against wilderness, most prominently William Cronon and J. Baird Callicott. This is odd, given that these writers seem to support two cornerstone positions of environmentalism as it has developed over the past twenty years: first, the view articulated within environmental ethics that wild, nonhuman nature, or at least some parts of it, has intrinsic or inherent value; second, the understanding developed within conservation biology that we have entered a period (...) of massive anthropogenic biodiversity loss and that landscape-level habitat preservation is essential for combating this. I argue here that Cronon and Callicott are wrong. In fact, an ethics of respect for nonhuman nature and an informed, scientific understanding of what is necessary to preserve it do strongly support increased wilderness preservation. (shrink)
