A while back, NPR reported on the very cool new book by a photographer who has focused his work on the poles. It sounds as if he's endured some hardships over the course of his career - bear aggression, frostbite, the usual - but the result are stunning photos that Paul Nicklen hopes will motivate people to preserve these remote wildernesses.
The best reason to read the story or buy the book, though, may be the encounter Nicklen had with a female leopard seal who tried to befriend him by bringing him a series of penguins in various stages of, well, being alive in hopes that she could feed him. I think it was a little rude of him not to eat one, no? It's difficult to catch penguins underwater - they move pretty fast.
