This entire thread is hijacked by talking about "cow farts". Meat, the way it's farmed today, is far more intensive than what meets the eye. There's the land required to raise the crops that feed the animals, there's transportation of this feed and the raw material to grow the feed, there's the deforestation caused by the land requirement, and on and on.
