But that hasn't stopped one US scientist calling 'bullsh*t' on claims made about meat producers' contributions to greenhouse gas (GHG) emissions. UC Davis animal science professor Frank Mitloehner says anti-animal advocates wrongly portray livestock as being to blame for most of the US's GHG emissions.
"When divorcing political fiction from scientific facts... from all sectors of society, one finds a different picture."
Scientists and the EPA say livestock production in the US accounts for just 4.2% of GHG, while transportation contributes 27% and the energy sector 31%.
