Photographer Brian Skerry has made a powerful case for protection of the world's marine environments during his recent presentation at TED. His imagery and words show the ocean's beauty but also how very fragile and vulnerable it is. The TED series of talks, devoted to "ideas worth spreading" are hosted by a small non-profit organization. Speakers have included Al Gore, Jane Goodall and Brian Greene. TED also runs local events and at the TEDx at Berkeley, Eric Cheng presented a talk about bioluminescent flashlight fish in Papua New Guinea, sperm whales and Architeuthis dux giant squid in Ogasawara, Japan and Dominica.
