Cows don't actually contribute any CO2, and humans don't either. Cows, like humans, can only generate CO2 by eating carbon-containing material. Cows eat grass. The grass was CO2 in the atmosphere only a week before they eat it. It's not important. If the grass dies and turns back into CO2 without the cow, it's just the same. It doesn't matter what the cows eat, because they don't ever eat petroleum or coal. They always eat something that was CO2 a little while before, and will be CO2 a little while later if they don't eat it. People are the same way. The methane is important, because it wasn't methane before they ate it. Grass + cows can convert CO2 to CO2, which is dull. It's too dull to talk about. The important thing is that grass + cows can convert CO2 to methane, and that is worth talking about. Methane is better insulation than CO2, and contributes more to global warming.
