Livestock raised for meat and milk accounts for approximately 17% of all the methane in the earth's atmosphere. The methane is produced in the rumen (stomachs) of the livestock and is released into the atmosphere through burping and flatulence. The solid waste from livestock also releases methane when digested by anaerobic bacteria during decomposition. Since a molecule of methane is 23 times more potent as a greenhouse gas (over a 100 year period) than carbon dioxide (methane is 63 times more potent over a 20 year span), the presence of methane from bovine flatulence and burping far outwe...
