"All animals release CO2. If we didn't convert wild plains into grazing, the buffalo would fart 18% of greenhouse gases."
All animals release CO2. The total release is number of individuals*release rate. Cattle get food, antibiotics, barns, water, protection from preds etc. Wild animals do not. That means that cattle can be grown in higher densities than wild animals, meaning that if we would convert farmland into prairie grassland and let the buffoloes roam free, they still wouldnt reach the same ammount of CO2 respiration that cattle have, meaning that it would be a net decrease in emissions. Btw, its not the CO2 that is the kicker with cattle, its the CH4 (methane) wich is a 23 times more efficient greenhouse gas than CO2.
