Common Dreams

In summer, some polar bears do not make the transition from their winter residence on the Svalbard islands to the dense drift and pack ice of the high arctic, where they would find a plethora of prey. This is due to global climate change which causes the ice around the islands to melt much earlier than previously. The bears need to adapt from their proper food to a diet of detritus, small animals, bird eggs and carcasses of marine animals. Very often they suffer starvation and are doomed to die.
