Seems like you're being pretty black&white about a complex issue. It's very difficult to find the "greenest" way to live, and it takes a lot of research and discussion. If you're not up to it, that's fine by me.

I think one good point here is that it is possible to eat meat that is sustainably produced, if that's the way you want to go. It will cost you more per pound of meat, but this might encourage you to eat more sensible amounts of meat. (By "you" I don't mean you personally.)

Besides, you do get what you pay for. Bear in mind that the USDA just recalled 143 million pounds of cheap hamburger because the cost-cutting producer got caught grinding up diseased animals. And they weren't caught by government inspectors because inspection is almost totally in the hands of the meat producers now. They were caught (in a manner of speaking) by "vege munching, bicycling hippie complete with kick ass piercings."

BTW--143 million pounds--that's more than one quarter-pounder for everybody in the country! That's a lot of bad burger....
