As the sibling already said: We're in a closed loop. Methane decomposes into CO2, so if you want to maintain a constant level of methane in the atmosphere, energy/mass conservation dictates that this carbon needs to come from somewhere else. Solution: It actually comes from the CO2, via grass growth & the cattle's digestive system. The amount of CO2, averaged over time, therefore cannot increase. |
