That is roughly equivalent of the farts of 6 mill cows, just standing there. Just saying for comparison, not for some "don't eat cows" agenda. Cow fart source

That is roughly equivalent of the farts of 6 mill cows, just standing there. Just saying for comparison, not for some "don't eat cows" agenda. Cow fart source: http://www.fastcoexist.com/3054212/collecting-cow-farts-the-stupid-brilliant-solution-to-global-warming http://www.fastcoexist.com/3054212/collecting-cow-farts-the-... (208l of methane farts = 135g/day. 120 days = 16.2kg. 97 x 10^6/16.2 = roughly 6 x 10^6.) Just smell that dairy air...

Yup. Imagine all that methane coming from ~1.5 billion cows on a yearly basis. I don't have to, it's happening already :D Methane is 80 times more potent (long-term) than CO2 for global warming. I personally can't wait for the economic prosperity of India and Africa. The beef and dairy business will top the oil one as the biggest pollutant, if it isn't topping already. Why are there no regulations and taxes for them?

  > The beef and dairy business will top the oil one as the biggest pollutant, if it isn't topping already. It isn't. Agriculture accounted for an estimated emission of 5.1 to 6.1 GtCO2-eq/yr in 2005 (10-12% of total global anthropogenic emissions of greenhouse gases (GHGs)). (IPCC AR4[0], slightly revised to 5.0 to 5.8 GtCO2eq/y in AR5) That's all agriculture, including livestock, this (IPCC AR5[1]) is just "cow farts": Enteric Fermentation. Global emissions of this important category grew from 1.4 to 2.1 GtCO2eq/yr between 1961 and 2010, with average annual growth rates of 0.70% (FAOSTAT, 2013).

Here's a 51% estimate, trumping everything else. http://www.worldwatch.org/node/6294 http://www.worldwatch.org/node/6294 No one can say with certainty. Although, raising 100 billion animals yearly, most of them having over 250lbs, I'd say it's pretty close for CO2. When it comes to methane, cow farts are 65% of our methane emissions. http://www.fao.org/docrep/010/a0701e/a0701e00.htm http://www.fao.org/docrep/010/a0701e/a0701e00.htm

To get technical on you, 95% of methane from cattle is from burps, not farts.
