Regarding CO2, seems like cows would only produce as much as they consume from feed that first captured that CO2 from the atmosphere, so if you are sourcing loc

  Cows produce huge quantities of Methane, which has a GWP of 40. They are a huge contributor to climate change.

    If you are growing the same quantity of cattle then their methane in the atmosphere would be at steady state, not growing and therefore not contributing to change. If you grow more cattle then more methane would be produced. On the other hand, isn’t cattle production displacing wild ruminants? If we stop producing cattle, will nature fill in with bison, deer, moose, etc? It's possible that methane from cattle isn't any higher than methane from the wild ruminants they replaced. Had this been studied?

      >their methane in the atmosphere would be at steady state, not growing and therefore not contributing to change. Assuming that methane is removed from the atmosphere by something? AFAIK methane doesnt get consumed by anything natural, so it should just be growing in an absolute sense as long as total cows (and other producers) are above 0

        No, methane degrades in the atmosphere with a half-life of around 9 years.
