Evidence-based approaches to animal welfare philanthropy can dramatically increase the impact of donations by focusing on the most cost-effective interventions.
The welfare impact of animal donations varies enormously depending on where funding is directed. Organizations working on farm animal welfare campaigns can secure commitments affecting millions of animals per dollar donated. Research and capacity-building organizations build long-term systemic change. The effective altruism approach to animal welfare asks donors to evaluate impact rigorously rather than giving based on emotional salience or proximity.
