Ok, this need clarification. The Polar bear is clearly no fake. And the image is not either. This Polar bear shot was taken early August in 2008 just about 120km north of Churchill in Manitoba Canada while the fireweed is blooming.

By making the letters ARCTIC bold we wanted to make clear that this about the ARCTIC & the ANTARCTIC.
