Al Gore stupidly says, "The climate crisis is not a political issue, it is a moral and spiritual challenge to all of humanity." The bit about morality isn't the stupid bit; most of the people I know agree that it is. I might agree with versions of it. Now, as far as I know, vegetarians have a much lower carbon footprint than meat eaters.
So my question to you meat eating global warming nuts is this; will you stop eating meat because of the morality issue? Or will you see tradeoffs where there were none before?
