True wilderness is where you keep it, and real wilderness experience cannot be a sedentary one; you have to seek it out not seated, but afoot.

I sort of kept my hand in writing and went to work for the Sierra Club in '52, walked the plank there in '69, founded Friends of the Earth and the League of Conservation Voters after that.

What we are finding out now is that there are not only limits to growth but also to technology and that we cannot allow technology to go on without public consent.
