Do animals such as cows increase CO2 levels?

Believe it or not. NO! Cows do not add add any CO2 They simply recycle what CO2 was previously there. A cow's only source of carbon is in the plants they eat. The plants they eat get their carbon from the CO2 in the air. If you get rid of the cows the plants will starve.

They increase CO2 depending on the population since they breath like we do. Also they produce a fair amount of METHANE due to digestion. As you have more cows/steers to make milk or meat it will go up.
