Wildlife diseases including sarcoptic mange, distemper, and white-nose syndrome cause enormous preventable suffering in wild animal populations.
Wildlife diseases cause prolonged, preventable suffering at population scale. Mange takes months to kill an affected animal through progressive skin damage and starvation. White-nose syndrome repeatedly wakes hibernating bats, exhausting fat reserves before they die. CWD causes a neurodegenerative death over months. For each of these diseases, treatments and preventions exist. The question is whether individual animal welfare justifies the intervention cost.
