Taking normal things and then mass producing them isn't a part of the normal carbon cycle, especially when areas are deforested or changed to make it more accommodating to mass production.
I'd love to read anything to the contrary - it's not that I believe cow farts is a horseman of a climate apocalypse.
But I find the idea of deforesting, mass animal production, the food used to feed cows being controlled (potentially causes more gas) far more unnatural than some extra cows in a field.
It's easy to say something is "natural" when referring to an animal existing, but the existence of these cows barely dips a toe in the natural world.
So if there is any legitimate proof that the beef/dairy industry don't contribute anything beyond the natural carbon cycle I'd love to educate myself!
I don't disagree that the main cause of CO2 emissions is clearly oil and gas, and that should absolutely be the focus. But to insinuate everything else is absolutely fine to ignore and Oil and Gas is the only source that can be mitigated seems disingenuous - especially since oil and gas aren't going anywhere anytime soon.
