Transitioning to a plant-based diet is the single most impactful individual action available for reducing farm animal suffering. Evidence-based guidance helps make the transition effective and sustainable.
Dietary change is the highest-leverage individual action for animal welfare because it directly reduces demand for the systems causing the most suffering. The focus on red meat reduction — while important for climate — misses the welfare calculus: chickens and fish are killed in far greater numbers per kilogram of protein consumed. Reducing chicken and fish consumption spares more individual animals per meal than eliminating beef. Plant-based transitions are most sustainable when they focus on substitution rather than deprivation — replacing familiar dishes with plant-based versions rather than adopting an entirely new cuisine. Imperfect reduction is valuable: a flexitarian who eliminates chicken and fish spares more animals than a dairy-free vegan who continues eating chicken.
