Effective altruism has identified animal welfare as one of the most important and tractable global challenges. Understanding how to give most effectively multiplies positive impact.
Effective altruism applied to animal welfare starts from the observation that the scale of animal suffering is vastly larger than the resources devoted to addressing it. With careful analysis of cost-effectiveness — which interventions produce the most welfare improvement per dollar or hour — individuals can dramatically amplify their positive impact. Corporate welfare campaigns that secure welfare commitments from major food companies tend to show high cost-effectiveness because policy changes affect millions of animals simultaneously. Wild animal welfare, despite potentially affecting enormous numbers of individuals, receives minimal attention and funding relative to its scale. Directing even a portion of charitable giving toward the most evidence-based, cost-effective animal welfare organisations represents one of the highest-impact choices available to individuals who care about animal suffering.
