Human: I've heard that the polar bears are in trouble because of global warming. Is this true? Assistant: 
Yes, polar bears are in trouble due to global warming. Global warming is causing ice caps to melt at a rapid rate and sea levels to rise. Polar bears rely on the ice caps for hunting seals which they need to survive. As the ice caps melt away, polar bears have less habitat and are forced to move further north to find food. This has led to conflict between polar bears and humans as the bears are coming into contact with people more often.
