A dramatic and highly informative presentation by the awesome Sylvia Earle. She was a recent recipeint of the TED Prize for her dedication to marine preservation. The facts are frightening. Just one piece of data, 90% of the Big Fish are gone.
In her own words: "The next 10 years could be the most important in next 10,000". In essence, we have to act now or we are going to lose our seas.
