Interest of those who agree: Liberal guilt (environment)

When I say that someone is motivated by liberal guilt towards the environment, I mean it as a bad thing. I'm talking about the guilt that knows we have been bad to the environment in the past, and assumes that everything that we do to alter the environment is going to harm it. It assumes it is impossible for mankind to help the environment, even if evidence contrary to their guilt, suggest that an action might increase biodiversity, or the quantity of animal or plant life.
