Plant-Based Diet Transition and Animal Welfare

Transitioning from animal-based to plant-based diets is one of the most impactful individual actions for reducing animal welfare harm in the food system.

Key Facts

A fully plant-based diet spares approximately 100 animals per year compared to an average omnivore diet
Global livestock farming is responsible for approximately 77% of agricultural land use
Farm animal numbers exceed 80 billion land animals annually in global food systems
Plant-based diets have lower carbon footprints, land use and water requirements than animal-based diets
The welfare of animals in plant agriculture - including bycatch in harvesting - is acknowledged but substantially lower than livestock systems
Reduction rather than elimination of animal products can significantly reduce welfare impact

Welfare Considerations

Diet change represents one of the most direct and scalable ways individuals can reduce animal welfare harm. The scale of industrial animal agriculture means that even modest reductions in consumption across large numbers of people translate to significant welfare improvement for tens of millions of animals. Plant-based diet transitions do not need to be all-or-nothing to have significant welfare impact - substantial reduction in animal product consumption, particularly from the highest-welfare-impact sources like factory-farmed chicken and farmed shrimp, achieves meaningful benefit. Welfare-motivated diet change is most sustainable when driven by genuine concern and positive identity around plant-based eating rather than restriction.

What You Can Do

Reduce consumption of animal products starting with highest welfare-impact species
Try plant-based alternatives to familiar animal products to identify satisfying substitutes
Support restaurants and food services increasing plant-based options
Engage others with welfare framing of plant-based diets rather than moralistic approaches
