The field of wild animal welfare examines the suffering of animals in natural ecosystems, challenging assumptions that nature is inherently good for the animals living within it.
Wild animals are not protected from suffering by living in natural conditions. The majority of wild animals that ever live die painfully from predation, starvation, disease, or exposure — often as juveniles. A mouse killed by a predator, a bird slowly starving after wing injury, or a fish dying of parasites all experience suffering that is not diminished by being natural. The welfare of wild animals challenges the nature-positive framing that assumes wild life is inherently better than captive life and opens new questions about the ethics of intervention versus non-intervention in natural suffering.
