I don’t know why we keep building these fucking dams,” Adams said in a surprisingly forceful British whisper. “Not only do they cause environmental and social disasters, they, with very few exceptions, all fail to do what they were supposed to do in the first place. Look at the Amazon, where they’ve all silted up. What is the reaction to that? They’re going to build another eighty of them. It’s just balmy. We must have beaver genes or something. . . . There’s just this kind of sensational desire to build dams, and maybe that should be looked at and excised from human nature. Maybe the Human Genome Project can locate the beaver/dam-building gene and cut that out.
