Isle Royale National Park faces a critical, long-term ecological imbalance driven by climate change, which has reduced the ice bridges needed for wolves to migrate from the mainland. This isolation caused severe inbreeding and a near-extinction of the wolf population by 2018, leading to an overpopulation of moose that overbrowsed vegetation, jeopardizing the ecosystem's health.
