Wild animals experience pain, disease, predation, and starvation at enormous scale. Acknowledging this reality opens important questions about our obligations to wild animal welfare.
Wild animal suffering at population scale is among the most philosophically challenging aspects of animal welfare. In natural systems, the vast majority of individual animals experience significant suffering during their lives — prey species die from predation, which involves fear and injury; juveniles of species with high fecundity mostly die from starvation, exposure, or disease; parasitism causes chronic discomfort across nearly all wild populations. The inability to intervene in most wild animal suffering does not reduce its moral significance, but it does limit our practical options. Some interventions are available: wildlife vaccination programs for infectious diseases, wildlife corridor design to reduce vehicle strikes, and pollution reduction all reduce wild animal suffering. The broader question of our obligations to wild animal welfare is an active and important philosophical debate.
