A study predicts  that Polar bears will be wiped out by the end of the century unless more is done to tackle climate change. As quoted by BBC.com (20/7) scientists say some populations have already reached their survival limits as the Arctic sea ice shrinks. The carnivores rely on the sea ice of the Arctic Ocean to hunt for seals. As the ice breaks up, the animals are forced to roam for long distances or on to shore, where they struggle to find food and feed their cubs. Dr Peter Molnar of the University of Toronto in Ontario, Canada stated the bear has become the "poster child of climate change. He said polar bears are already sitting at the top of the world; if the ice goes, they have no place to go//bbc
