Rewilding programs restore ecosystem function through natural processes and keystone species reintroduction, but raise complex welfare questions about individual animals navigating restored ecosystems.
Rewilding creates ecosystems where natural predation, competition, and environmental challenge cause individual animal suffering that would not occur without human intervention. This creates ethical tension between ecosystem restoration and individual welfare. Ethical rewilding frameworks acknowledge these individual welfare costs and monitor them, accepting some increase in individual suffering for ecosystem-level benefits.
