The Polar Bear, the world's largest terrestrial carnivore is smart, unpredictable and extremely dangerous. Every October, the migration of more than 1,000 bears sends them on a collision course with a small town in Northern Canada. This Great Ice Bear Event begins every October on the western shore of Hudson, in Churchill, Manitoba. In fact, with a population of 1200 animals, more bears live around here than people.
