Dear WWF,
My friend, Jane and I have been doing some research on endangered animnals. We found that the habitat of the polar bears is disappearing because the North Pole is getting warmer and the ice melting（融化）. I worry that when it disappears altogether, there will be nowhere for the polar bears to live.
