I was referring to CO2 produced through breathing, as you had just said:
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.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...
