Just a quick bit of research from the Internet, which never fails me:
Does the quantity of methane in cow farts get balanced out by the number of vegan farts should we all become vegans? Because vegans fart, and I want to make sure we have solid science behind the claim of having less cows creating less methane-by-cows… but the methane from humans? Do vegans produce less methane than cows in unit time?
