The suffering of wild animals from predation, disease, starvation, and adverse weather represents an enormous moral problem that welfare philosophy is only beginning to address systematically.
The scale of wild animal suffering is staggering when considered honestly. A single breeding season in many species produces thousands of offspring that die from predation, starvation, cold, or disease before reaching maturity. Each of those deaths involves varying degrees of fear and pain. The philosophical question of whether we have obligations to reduce this suffering — and if so, what interventions would be appropriate and effective — is one of the most challenging in applied ethics. The welfare movement is slowly engaging with this question, moving beyond a focus on human-caused suffering to consider the full scope of animal suffering wherever it occurs.
