Rewilding programs restore ecosystem function through large predator and herbivore reintroduction, with complex welfare implications.
Rewilding involves deliberate acceptance of some individual animal suffering through predation in exchange for larger-scale ecosystem welfare benefits. The welfare calculus is complex: predation events cause acute suffering for prey individuals but may reduce chronic disease and starvation mortality at population level. Transparent acknowledgment of these tradeoffs strengthens the ethical case for rewilding.
