Polar bears usually like seals, their cubs, and their ice. The ice keeps the polar bears cold, because polar bears live in an environment where they are surrounded by ice. Their cubs because they have to feed their cubs daily, and their cubs have to stay warm, because they are young, and they have to be fed. The seals because seal is what polar bears eat. Seal contains all the nourishment that a polar bear needs to survive in its habitat.
