Cattle on ranchland can easily be CO2 negative. Soil is a great carbon sink. So as long as the quality of the soil is increasing, we're removing CO2 from the atmosphere. Cattle and Buffalo are great for the soil, unlike other grass consumers like sheep.

Methane is a more difficult problem. It's mostly soluble with specific supplements and other mechanisms, but it's an expensive process that ranchers won't pay for unless there are proper incentives.
