That's interesting. It shows the struggle of sustainable solutions: Water power vs fish population; wind power vs bird population. Such arguments, however, are distorted by lobbyists of coal, oil and gas. After all, no one is asking how many fish or birds are killed by coal, oil or gas - and it's certainly a lot. Essentially, water and wind power production must be preferred, but unfortunately it's not always the case. While it might make sense in this concrete example to tear down the old damn, there are so many other renewable projects that fail because of this discussion...
