Recently I saw a programme about polar bears. Bears forced to swim too long drown. A polar bear was shown swimming and looking for land. It took him five days before he found land. He was desperately hungry but a colony of walrurses protected themselves so well with tusked males on the outside of the ring that he failed to make a kill and then colony took to the sea. The bear was so weak and so injured that he could only lie down on the ice and die. It seemed such a sad end to all his efforts.
