The total Green House Gas Emissions (GHGs) attributable to livestock products (their manufacture, waste, land use, and transportation) is greater than 51% of the total GHG driving the climate crisis now (methane, CO2, nitrous oxide) [1] . This exceeds the total for all coal and oil driven forms of transportation combined, by a large margin. Replacing animal based foods with plant based ones is a far more effective method for GHG mitigation than changing animal agriculture technology. [2]
