Polar bears definitely have height and weight advantage on
land.
But as for seals, it's completely new to me. But if polar bears are
known to kill whales, something must be able to kill them or the
whole ecosystem would be upset.
But I wonder about this comment:
'If a polar bear and a lion had a fight who would win?' That
depends on the terrain.

It does make some sense too. Bring it to the tropics and the
polar bear would die first. Or maybe I'm wrong? Nature is
definitely fun to study.
