Animal welfare science is a rapidly evolving field identifying new priority areas and interventions to reduce suffering at scale.
The history of animal welfare science demonstrates that rigorous evidence changes policy, industry practice, and public attitudes. Battery cage bans, non-lead ammunition laws, and dolphin-safe fishing regulations all emerged from scientific documentation of welfare harms. Continued investment in welfare science - especially for understudied species like fish, insects, and wild animals - is among the highest-leverage interventions for improving animal lives at scale.
