Paul Nicklen is a wildlife biologist turned nature photographer. In this talk Nicklen discusses his work as a photographer and problem of melting polar caps with a passion and sadness that cannot be faked. He receives a standing ovation for this heartfelt presentation and, in my opinion, is a likely contender for TED.com talk of the year. If you haven’t seen it yet, you must watch it now!
