Deliberate and accidental poisoning kills millions of wild animals annually. Understanding the scale and addressing the causes reduces enormous suffering in wildlife populations.
Wildlife poisoning causes massive, largely invisible suffering across many species. The suffering is often prolonged: lead poisoning causes neurological damage over days to weeks; anticoagulant rodenticides cause internal bleeding over days; some nerve agent pesticides cause convulsions. Non-target species include many protected and endangered species. Effective alternatives exist for most poisoning purposes, including lead-free ammunition, non-toxic rodent control, and non-lethal predator deterrence. Policy change, hunter education, and enforcement are key to reducing poisoning-related wildlife suffering.
