Effective Altruism and Strategic Animal Advocacy

Effective altruism principles applied to animal advocacy help identify the most cost-effective interventions for reducing animal suffering at the largest scale possible.

Key Facts

Factory farmed animals represent over 99% of animals killed by humans annually, by number
Corporate animal welfare campaigns have been shown to improve conditions for hundreds of millions of animals per dollar spent
Fish welfare interventions are often highly cost-effective due to the enormous number of fish in food systems
Wild animal welfare encompasses potentially the largest population of sentient animals on earth
Funding for animal advocacy is dramatically lower than for human health interventions affecting fewer individuals
Research into neglected questions — insect welfare, wild animal suffering — may have the highest marginal impact

Welfare Considerations

Strategic animal advocacy guided by effective altruism principles focuses resources where they can reduce the most suffering. This means prioritizing farmed animals — who vastly outnumber companion animals or those targeted by traditional animal protection — and within farmed animals, the species in the worst conditions affecting the most individuals. It means funding research into neglected areas, supporting corporate campaigns with demonstrated impact, and making evidence-based decisions about which charities to support. This framework does not eliminate the value of all forms of advocacy but helps ensure that limited resources translate into maximum reduction in animal suffering.
