While the percentages vary by study, mhorndisk is correct in noting the world's growing consumption of "food animals," and the sizable amount of methane they create, is a particularly harmful element related to climate change. There's a lot of supportive data out there, but here's a nice article from NPR…
Bearing in mind that agriculture accounted for nine percent of greenhouse gasses by sector: "In 2011, methane from livestock accounted for 39 percent of all the greenhouse gas emissions from agriculture, according to a report that United Nations Food and Agriculture Organization released Friday. That's more than synthetic fertilizer or deforestation."
So yes, mhorn's numbers are inflated. And yet, animals/methane remains an important part of the climate change equation.
mhorn, it's my sense that you get downvoted – even here, on a topic in which many of us agree with parts of your position -- because your forum manners are so very poor. And yes, we know you don't care.
Why the need, on this thread, for umpteen little, enraged, complaining replies to your own message? When you routinely type with all those screaming caps -- here, DEAD FLESH and such -- you do your case more harm than good. It's called self-control, and until you learn some, you'll get down-votes -- even on issues where you might have unexpected allies.
