Investigation:

Polar bears are an endangered species that live in Antartica. Recently, scientists who study polar bear populations have noticed that many bears have started losing their hair and some are even developing large oozing lesions as you can see in the picture to the right. Scientists believe that the cause of the skin condition is tied to human activity.

1) What could be causing the hair loss and skin conditions of the polar bears?

2) How could it be related to the activities of humans?
