" All the discussion in the meeting that day had centered on the impacts to humans. That would be the usual way of most such discussions; but whole biomes, whole ecologies would be altered, perhaps devastated. That was what they were saying, really, when they talked about the impact on humans: they would lose the support of the domesticated part of nature. Everything would become an exotic; everything would have to go feral. "

― Kim Stanley Robinson , Fifty Degrees Below (Science in the Capital, #2)
