“A sustainable diet leaves room for 2 chicken breasts a week”
(Really, 2 servings of fish / poultry per week. No red meat.)
The average person outside of developing nations vastly outpaces this consumption rate.
The small, single-digit percent of the population that’s vegetarian/vegan, as well as people who are experiencing food insecurity and do not have consistent access to meat are ahead of the curve from a sustainability perspective.
When 95+% of people who have the means to dictate their meal choices do not achieve the target reduction it’s generally safe to say everyone who eats meat needs to cut back.
