- devoutsalsa 6y agoWhen grass naturally, does it produce methane? EDIT: it must be part of cow digestion. I just remember that cow burbs are bigger methane problems, but cow farts are fine. Still not sure about methane from grass dying normally, and maybe there’s lots extra grass being grown for cows that wouldn’t grow normally?
- buran77 6y agoAerobic decomposition, exposed to oxygen like dead grass on the ground, produces mostly CO2 and H2O (plus some other O based stuff like SO4, PO4, NO3). Anaerobic decomposition, like in a cow's stomachs, produces mostly CH4 and CO2 (plus some other H based stuff like NH3, H2S, PH3).
- lcamach84 6y agoWhen the herd eat grass it stimulates grass growth and grass is a huge carbon sink. there is a cool ted talk about this. https://www.youtube.com/watch?v=vpTHi7O66pI https://www.youtube.com/watch?v=vpTHi7O66pI
- jules 6y agoIf you put the grass where nothing grew before, like a desert. The situation in reality is the opposite: people make forests into grassland.
