This is Dr. Sylvia Earle, renowned marine oceanographer who won the TED prize this year. The video is well worth watching and it includes beautiful underwater footage of marine life from around the world, along with Dr. Earle's passionate discourse on what the oceans mean to us. This is her wish:
"I wish you would use all means at your disposal -- films! expeditions! the web! more! -- to ignite public support for a global network of marine protected areas, hope spots large enough to save and restore the ocean, the blue heart of the planet."
