On September 11, in the remote backcountry of Grand Teton National Park, a black bear was euthanized — not for what it did, but for what it had learned. Over months of accumulated human carelessness near Delta Lake, the bear came to understand that people meant food, and that lesson, reinforced again and again by visitors who left meals unattended, ultimately made the animal's continued existence incompatible with human safety. It is an old and painful story: wildness undone not by malice, but by the quiet erosion of small, unconsidered choices.
