To quote Ron White, I'm eating a cow. They are, according to this report, responsible for 18% of greenhouse gasses.
Just because the environmentalist religious nuts scream that raising and eating cattle is wrong, wrong, wrong, does not mean that most people will instantly turn vegan.
It's an especially stupid attempt with more and more doubting that global climate shift is a destructive shift toward warming, that we're warming at all anymore, and that it wouldn't be human-caused even if we were still warming.
