Sea ice is like a moving sidewalk and they travel with it, according to Elizabeth Peacock. As the ice melts, and the density of ice is found in different areas then more bears are likely to move. As more bears are likely to move, it creates a situation where more bears are led to leave. Polar be

Polar bears heading to Arctic islands for more food, new research suggests
paper, published Jan. 6 in the online journal Plos One, whose authors include former Government of Nunavut polar bear biologist Elizabeth Peacock, provides genetic evidence that also points to movement by polar bears to the Arctic islands, where the polar bears can find better seal-hunting conditions.
"In general, polar bears move with their habitat," Elizabeth Peacock, a US Geological Survey (USGS) researcher, explained to Discovery News. "Sea ice is like a moving sidewalk and they travel with it," she continued. "Bears likely move towards places with better access to prey and mates."
Individual animals are not marching northward en masse, according to Elizabeth Peacock, a U.S. Geological Society researcher who recently studied polar bears. Rather, the population distribution shifts appear to be gradual and subtle.
