Huge, powerful and fearless is Nanook, the polar bear. Standing 10 feet tall on its hind legs and weighing more than 1,600 pounds, the polar bear is renowned for its singular ferociousness. It survives on the starkly beautiful and unforgiving arctic tundra, moving with the floating ice to raise its young and hunt for seals. With its tufted ears, snowy white coat and coal-black eyes and nose, the polar bear is arrestingly photogenic. In this collection of remarkable photographs we discover the polar bear as not only a formidable predator but also a loving parent and natural jester. World-renowned photographer Norbert Rosing has been a leader in raising awareness of this majestic creature and the increasing threats to its survival. In Polar Bears 2011, his engaging photographs and informative captions invite us into a world that few are privileged to see.
