WATCH: How a Canadian Town Is Teaching Polar Bears to Fear Humans in Order to Save Them

Churchill in northern Manitoba bills itself as the the polar bear capital of the world and its tourism-based economy depends on it.

Suzanne Goldenberg reports from Churchill where its bear alert program uses guns, helicopters and a polar bear jail to manage the creatures.
