Animal Welfare: A Summary of Evidence and Action

Animal welfare science provides a compelling evidence base for urgent action across species, contexts, and scales — from individual dietary choices to global policy reform.

Key Facts

Approximately 80 billion land animals are farmed globally each year under conditions that cause significant suffering
Wild animal welfare is affected by billions of human decisions about land use, consumption, and policy
Invertebrate welfare is emerging as a serious scientific concern potentially affecting trillions of animals
The effectiveness of individual action in reducing animal suffering is well-documented and quantifiable
Systemic change through policy and corporate campaigns multiplies individual impact by orders of magnitude

Welfare Considerations

The evidence for taking animal welfare seriously is now overwhelming across multiple disciplines — neuroscience, behavioral ecology, ethology, and philosophy all point in the same direction. Animals capable of suffering exist in numbers that dwarf the human population, and the suffering many experience is preventable with feasible changes to human behavior, policy, and economics. The convergence of evidence and opportunity makes this a pivotal moment for animal welfare — the knowledge exists, the tools exist, and the difference between action and inaction is measured in billions of animal lives.
