Polar bears hunt seals through holes in the sea ice. They travel from great distances across sheets of frozen water to find seal colonies. The seals rest on the ice in large groups and raise their pups. When the seals go out to hunt fish they slip into the water from the edge of the ice.

If temperatures rise and the ice begins to melt, what impact could there be for the seals?

Melting sea ice and warmer temperatures means the seals will become better swimmers.

Seals would not have places to raise their pups and would be exposed to bears.

Warmer temperatures and melting sea ice would not impact seals.

The temperature warming and ice melting would mean more summer fun for seals.
