So *THIS* is where all the greenhouse gases come from. (spoiler: cow farts are only 5.6%)

1. ... and the vast, vast majority of natural gas ends up as CO2,...

... not spewed as methane, as so many declare.

2. Though methane has a much greater warming effect

For example, the 20 year GWP of methane is 72, which means that if the same mass of methane and carbon dioxide were introduced into the atmosphere, that methane will trap 72 times more heat than the carbon dioxide over the next 20 years.

And it should be noted, vast swaths of land are cleared for growing food and grazing (see "Land Use Change&quot , releasing CO2 locked away in the foliage and soil. Our approach to agriculture is a dirty, nasty part of the global problem.

3. Damn you, science! Damn you, fact-loving critical thinkers!

I'm wondering, based on the pitch of the graphic, whether the 5.6% already includes calculations of the relative impact of cattle flatulence. I mean, frankly, 5.6% from cows vs. 29% from smoke stacks already seems like a low ratio for industrial pollution.
