I think choosing to walk or ride your bike one day out of the week is probably a viable (maybe even more effective?) alternative.
That's the funny thing -- the meat industry causes more greenhouse gases than any other industry.
So if you take the volume of greenhouse gasses produced per hour and divide it by the population, it's greater than what you'd produce from driving an average car around for an hour? Do you have sources?
The article I quoted in the first post basically says that.
But here's another, also from the UN:

google cache version)
I'm also not saying that you should drive more and eat meat less, that would be basically the same mistake as what rabbit said -- that cutting down is irrelevant. Everything helps.
And incidentally, eating vegetarian can be great. Falafels, any kind of pasta (tomato/mushroom sauce is awesome, as is garlic/lemon sauce), cereal/oatmeal/toast (I like plain cereal/oatmeal with fresh or freeze dried fruit), veggie wraps with hummus, various kinds of soups, breads (I like focaccia loaf), pizza, stews, stir fries with rice or noodles (I like using fresh garden vegetables, anything can basically be fried together. Right now is harvest time, so it's awesome!), to name a few. Now I'm hungry.
But yeah, one day a week, it can't hurt! And it's not a zero sum -- nothing's stopping you from doing both!
I think the fact you're eating an intelligent, feeling animal is much more of a turn off than the prospect that it might contribute to global warming, or that it might be unhealthy.
Heh, I agree 100%, but that argument is irrelevant in this thread.
