A vegan diet eliminates direct consumption of animal products, offering significant reduction in individual contribution to farm animal suffering while raising questions about indirect impacts.
Veganism is the dietary choice most directly and substantially reducing farm animal suffering at the individual level. The numbers are stark — each person who adopts a vegan diet is responsible for the killing and suffering of roughly 90% fewer farm animals over their lifetime. This matters because farm animal suffering is the largest source of human-caused animal suffering on the planet. Indirect impacts — wild animal deaths in crop production — are real but much smaller in scale. Vegan diets also have significant co-benefits for climate, land use and public health that amplify their welfare case.
