For centuries, humans have relied on the oceans for resources and food... but even the deepest sea has its limits. This hour, TED speakers discuss how we can save our seas to save our planet. Guests include marine biologists Asha de Vos, Ayana Elizabeth Johnson, and Alasdair Harris, and oceanographer Sylvia Earle. Original broadcast date: June 25, 2021.
