Methane is short lived in the atmosphere. Also, North America historically had about 300 million ruminants, before human intervention: bison.
The other issue is we’re basically running out of topsoil. Modern agriculture is an extractive process, and the result is we have maybe 60 years left until the topsoil is gone and we can’t grow any more crops.

Taking that into account: The 20-year global warming potential of methane is 84.[5][6] That is, over a 20-year period, it traps 84 times more heat per mass unit than carbon dioxide (CO2) and 32 times the effect when accounting for aerosol interactions. https://en.m.wikipedia.org/wiki/Atmospheric_methane https://en.m.wikipedia.org/wiki/Atmospheric_methane
