Cruising the high arctic. As you get further towards the top of the world, the curvature of the earth gets more pronounced. The icebreaker was having no problems, as the ice was breaking up, and is continuing to do so year on year. This is causing big problems, however, for polar bears, as there are fewer floes that will support their weight without tipping. Polar bears are excellent swimmers, but in recent years more and more are becoming exhausted and drowning as a result of being unable to haul out.
