What do you consider the most interesting man-made structure in the galaxy?The dam they are building at the Three Gorges on the Yangtse. Though perhaps 'baffling' would be a better word. Dams almost never do what they were intended to do, but create devastation beyond belief. And yet we keep on building them, and I can't help but wonder why. I'm convinced that if we go back far enough in the history of the human species, we will find some beaver genes creeping in there somewhere. It's the only explanation that makes sense.
