Wild animal suffering from predation, disease, starvation, and environmental stress exists on a massive scale that welfare philosophy is increasingly grappling with.
Wild animal suffering is among the most philosophically challenging welfare questions. The scale of natural suffering - from parasitism, starvation, injury, predation, and disease - vastly exceeds human-caused animal suffering in numbers. Most welfare philosophers agree that avoiding unnecessary increases in wild animal suffering through habitat destruction, pollution, or climate change is a clear obligation. More interventionist positions are more contested but deserve serious ethical consideration.
