I was referring to CO2 produced through breathing, as you had just said:
The carbon that is exhaled is cycled, not added to the atmosphere as that carbon is taken from the atmosphere to begin with to become the food we eat...
I wondered why there isnt a cycle for methane, considering that there has almost certainly been methane production on the same scale as our current cow population throughout the planet's history (somehow I dont believe that dinosaurs didnt have similar bodily functions as modern bovine.) That earth hasnt turned into mars from it indicates there must be some countering force.
