Ok, does that mean that we should drain the Great Lakes so we can "restore" them as valleys with their own ecosystem? (supposing that we could make them off limits to building, so Chicago and Gary and other cities on what are now lakes couldn't encroach; and never mind that we don't know what they were like before the glaciers carved them out, or if they were even valleys back then) Would that be better in some objective way?
