Effective Altruism and Animal Advocacy Priorities

Applying effective altruism principles to animal advocacy helps direct limited resources toward interventions with the greatest impact for the most animals.

Key Facts

An estimated 80 billion land animals are farmed annually, vastly outnumbering wild vertebrates
Corporate campaigns have secured welfare commitments covering billions of animals at relatively low cost
Farmed fish likely number in the hundreds of billions to trillions annually, with very limited welfare protections
GiveWell-equivalent animal welfare analyses suggest the most cost-effective interventions target factory farming
Wild animal suffering represents an enormous and largely unaddressed welfare frontier

Welfare Considerations

Effective animal advocacy applies evidence and reason to identify where limited resources can do the most good. Scale, neglectedness and tractability help identify high-impact areas. Factory farming — affecting the greatest number of animals with the most severe suffering — is the dominant priority by scale. Wild animal suffering is vast but tractability is currently low. Donating to highly cost-effective organisations identified by Animal Charity Evaluators, advocating for corporate welfare commitments and shifting consumption patterns all represent high-impact individual actions. Thoughtful prioritisation amplifies the welfare impact of every dollar and hour invested in advocacy.
