The real truth of the nut case left is they are so entrenched in self loathing they long for the elimination of the human race.
They want us to live in caves.
Actually, the nutcase left is also against building dams. But not because they cause greenhouse gas (most of the nutcase left didn't know about this previously) but because anything that aids in the economic development of the human race is evil to the nutcase left, and the nutcase left wants to destroy.
It is true, though, that nutcase left opposition to nuke power and fossil fuel power has made building dams more attractive than it might otherwise have been.
Ah, the nutcase left. Were would we be without them? I know! Way up there. Way far ahead of where we are now.
It sounds more like they're opposed to ALL carbon-based lifeforms, animal and vegetable alike.
Man, as a conservative, I have a very strong pro-life philosophy.
But I don't think it's possible to achieve zero-emissions by legislating a ban on death, decay and decomposition of all biological matter.
