Ocean Protection Has Worked Locally, but 97 Percent Remains Exposed

Marine biologist Sylvia Earle returned to TED to assess the ocean-protection campaign she launched there in 2009, arguing that the sea should be treated not as scenery or resource stock but as Earth’s life-support system. Her case is that industrial extraction is depleting the wildlife that keeps that system functioning, while the Hope Spots network shows protection and restoration can work in specific places. The remaining gap, she says, is scale: most of the ocean is still open to exploitation, and known remedies now depend on political and public will.
