Paul Greenberg: The four fish we're overeating -- and what to eat instead

The way we fish for popular seafood such as salmon, tuna and shrimp is threatening to ruin our oceans. Paul Greenberg explores the sheer size and irrationality of the seafood economy, and suggests a few specific ways we can change it, to benefit both the natural world and the people who depend on fishing for their livelihoods.

Angelicque White: What ocean microbes reveal about the changing climate

When the ocean changes, the planet changes -- and it all starts with microbes, says biological oceanographer Angelicque White. Backed by decades of data, White shares how scientists use these ancient microorganisms as a crucial barometer of ocean health -- and how we might rejuvenate them as marine temperatures steadily rise.

David Lang: Let's protect the oceans like national parks

You don't have to be a scientist to help protect the world's oceans, says underwater drone expert and TED Fellow David Lang -- in fact, ordinary citizens have pulled together to save the planet's natural treasures many times in history.

Damian Palin: Mining minerals from seawater

The world needs clean water, and more and more, we're pulling it from the oceans, desalinating it, and drinking it. But what to do with the salty brine left behind? In this intriguing short talk, TED Fellow Damian Palin proposes an idea: Mine it for other minerals we need, with the help of some collaborative metal-munching bacteria.

Jason deCaires Taylor: An underwater art museum, teeming with life

For sculptor Jason deCaires Taylor, the ocean is more than a muse -- it's an exhibition space and museum. Taylor creates sculptures of human forms and mundane life on land and sinks them to the ocean floor, where they are subsumed by the sea and transformed from lifeless stone into vibrant habitats for corals, crustaceans and other creatures. Th...

Ayana Elizabeth Johnson and Megan Davis: Underwater farms vs. climate change

For billions of people, seafood provides a significant source of protein and nutrition, but over half the seafood we eat isn't caught in the wild, it's grown through aquaculture. Farmed seafood is one of the fastest-growing food industries, but the farming methods echo the problems we've seen in industrial agriculture. Is there a way to sustaina...
