Paul Nicklen gave a Ted talk in 2011 where he showed this beautiful slideshow of an Antarctic animals set to music which includes some great shots of a rare white bear. He also got some great shots of leopard seals when he got into the water with them. Besides having very beautiful photographs, the talk also has some humor in it. But the main point of the talk is to generate awareness of the global warming problem and its danger to the wildlife that inhabits the icy world. You also see a photograph of a dead polar bear.
