This week on the TED Radio Hour - An SOS From The Ocean.

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.

First up - Whales are more than just beautiful creature, they play a vital role in the ocean's ecosystem. Marine biologist Asha de Vos explains why protecting whales is crucial for protecting the entire sea.

For marine biologist Ayana Elizabeth Johnson, not knowing where our seafood comes from isn't just a mystery— it's a problem. She says we should reconsider what we eat and how we take it from the sea.

In 1998, Alasdair Harris went to Madagascar to research coral reefs. He's worked there ever since. He explains the true meaning of conservation he learned from the island's Indigenous communities.

Finally - Legendary oceanographer Sylvia Earle has been exploring and working to protect our oceans for more than half a century. Her message has stayed the same: we're taking our oceans for granted.
