Not all animal welfare charities are equally effective at reducing suffering. Evidence-based approaches to charitable giving can multiply the impact of each donation.
Effective animal advocacy requires prioritising interventions that reach the most animals with the most welfare impact per dollar. Individual rescue is valuable but expensive per animal helped. Corporate campaigns that shift company policies on cages or stunning affect millions of animals. Policy advocacy that changes regulations affects entire industries. Research into sentience and effective interventions multiplies all downstream work. The effective altruism approach to animal welfare suggests that careful prioritisation of where to give and what to advocate for can multiply impact by orders of magnitude compared to intuitive giving.
