There is a polar bear jail in Canada⁠⁠The town of Churchill in northern Manitoba, visited by a thousand polar bears in the summer, has a special facility for the most troublesome or dangerous of these special visitors: nothing else than a jail, comprising about fifty cells where the bears are locked up to one month and without food. After that, they are flown far away from the town with a helicopter. The theory is that this would be memorable enough for the bear that they won’t want to approach the town ever again, even though they cannot find food anywhere else any more since the ice in the region has melted and their usual food, seals, are now not that common.
