We’re keeping the ocean wild — and you can join us | Sylvia A. Earle

In 2009, marine biologist Sylvia Earle stood on the TED stage and made a wish: to build a global network of "Hope Spots" and protect the ocean before it's too late. Seventeen years later, she's back to report on what's happened since — and the picture is both more urgent and more hopeful than you might expect. From 100,000 fur seals saved from near-extinction to coral reefs rebuilt clam by clam, Earle says we already know exactly what needs to be done; the only thing left is to find the will to do it.

(Following her talk, Elise Hu, host of TED Talks Daily, interviews Earle on how she uses AI to gather data on the ocean and what she saw in a one-person submarine surfacing off the coast of Hawaii during a storm.)
