Individual dietary choices to reduce meat consumption are among the highest-impact personal welfare interventions available, with evidence on effectiveness, substitution patterns, and social influence.
Reducing personal meat consumption is one of the most direct welfare impacts an individual can make, and the animal welfare case is distinct from and complementary to the environmental case. The welfare argument specifically prioritises reduction of chicken, egg, fish, and farmed shrimp consumption due to the enormous numbers of individual animals involved. Strategic consumption reduction — choosing the highest-welfare available option, reducing the lowest-welfare most-consumed items, and supporting institutional food environment changes — has greater impact than all-or-nothing dietary transformations that many find unsustainable.
