A number of years ago, I got into a cocktail-party argument (or its boho-pomo equivalent, since we were in San Francisco in the 1980s) with someone who decried the “unnaturalness” of spaceflight. Her thesis, IIRC, was that humans were somehow apart from and opposed to Nature, as evidenced by the fact that “we make stuff instead of using what’s already there.” I asked, “What about beavewr dams and birds’ nests?” She got mad and found another people-knot. Would but that I could have steered her http://www.nextnature.net/-ward!
