man thats awful! i remember when i went to sea world in orlando when i was about 7, and we went in to see the polar bear, the enclosure was about the size of my living room...not big.....and was mostly water with a sliver of ice the opposite side from the viewing glass. the bear just sat there rocking on its haunches and its head swaying from side to side. it was really sad, i burst in to tears and my mum had to take me out. i know sea world dont harm their animals and mostly they have good size enclosures, it was just this one bear. so i havnt been for years (my mum wouldnt let me go back lol) but i fully intend to take my lil girl there next year x
