The Nursery Hack That Pays for Itself
How To Protect The Ocean
Coral nurseries need constant maintenance, and that maintenance is expensive and relentless. When Andrew talked to Mike Goldberg, co-founder of I.CARE, his answer wasn't to hire more staff. It was to let paying customers do it for the fun of it. Mike owns a dive shop in the Florida Keys, so the paying customers are scuba divers, and over the years he's built a funding model so small that nobody has ever really complained about it. None of that makes sense until you understand what coral actually is. It's an animal, not a plant or a rock: what looks like one coral "head" is really a colony of...

He Almost Quit the Dive Business. Then a Coral Reef PhD Student Walked In.
How To Protect The Ocean
Mike Goldberg had over 10,000 dives and decades running a dive shop in the Florida Keys, enough time to have seen the reefs at their pristine best. Then came a coral bleaching event in 2008, and a few years later, Stony Coral Tissue Loss Disease, a still-unexplained outbreak that's killed coral tissue outright across more than 20 of Florida's roughly 45 stony coral species since 2014. At one point his wife told him directly: the reef isn't what it used to be, and it's not getting better. Get out of the business before there's nothing left to sell. He didn't know what to do about it. Then,...

84 Percent: Inside the Worst Coral Bleaching Event Ever Recorded
How To Protect The Ocean
This year, most of the coral on the planet went through heat stress severe enough to bleach it. That's not a rounding error: 84 percent of the world's reef area, across the Pacific, Atlantic, and Indian Oceans, and NOAA had to add three brand-new alert levels to its Coral Reef Watch scale because the existing one had no category for what was happening. In this episode, Andrew breaks down exactly where global coral reefs stand right now: how the fourth global mass bleaching event on record got declared, why NOAA waited until 2026 to confirm it had actually ended, and why every global bleaching...

Everyone in the Tent: How Ocean Treaties Actually Get Made
How To Protect The Ocean
Holly Koehler has spent almost thirty years in rooms most people never think about: windowless UN offices in New York, the FAO in Rome, and what she calls "oftentimes very boring hotel ballrooms around the world," where countries hash out how the ocean actually gets managed. She's the Vice President of Policy and Outreach at the International Seafood Sustainability Foundation (ISSF), and before that she spent thirteen years at the U.S. State Department's Office of Marine Conservation, chairing international fisheries negotiations. In this episode, she walks Andrew through how a grad-school...

Inside the System That Makes a Seafood Label Trustworthy
How To Protect The Ocean
Between a fishing vessel out on the water and a can of tuna in your grocery cart, there is a complex, little-understood system working to verify whether you should trust what is on the label. In this episode of the How to Protect the Ocean Podcast, host Andrew Lewin breaks down how that system actually works, and why the blue check mark on your seafood means something real. Andrew starts with the RFMO, a regional fisheries management organization: a treaty-based body where countries with a stake in a fishery legally bind themselves to cooperate on how it is managed. He walks through where...

The Ship Has Reached the Shore: The High Seas Treaty Explained
How To Protect The Ocean
There's a video online of a room full of exhausted diplomats breaking into applause after nearly 20 years of work. One woman brings down the gavel and says, "the ship has reached the shore." That moment, in March 2023, closed out a negotiation that had already failed once in public. It became binding international law this year, and the fight over what it actually protects is happening right now. In this episode, Andrew traces the full history of the High Seas Treaty, formally the BBNJ Agreement (Biodiversity Beyond National Jurisdiction): from the idea first raised at a UN Oceans working...

Corals Nearly as Old as the Pyramids, and the Fight to Save Them
How To Protect The Ocean
Somewhere on the ocean floor right now, a coral colony has been growing since before the Great Pyramid of Giza was finished. One deep-water black coral off the coast of Hawaii has been dated at 4,270 years old, making it one of the oldest living skeleton-building organisms known to science. A single pass of a bottom trawl net can wipe out that kind of habitat in seconds, and it's a fight that's still being decided this very year at the United Nations. In this episode, Andrew breaks down why bottom trawling is such a hard problem to regulate. It's rarely the fish stock itself that takes the...

A Summer Internship, Thirty Years, and One Career for the Ages
How To Protect The Ocean
A grad student faces a simple choice: write another term paper, or take a summer internship. She takes the internship, gets assigned to sea turtles, and thirty years later she is in the room for some of the most consequential ocean policy agreements ever negotiated. This episode traces that career from the beginning, and it starts with a realization that shapes everything that follows: sea turtles do not read maps. They cross every border humans have drawn, which means protecting them requires countries to cooperate, not compete. Andrew walks through the arc of this career step by step. It...

Deep Sea Mining Exposed: Inside the Fight to Save the Ocean's Last Frontier
How To Protect The Ocean
Deep sea mining is no longer theoretical. In this episode, Andrew sits down with Matthew Gianni, co-founder and Political and Policy Advisor of the Deep Sea Conservation Coalition, for an in-depth look at what's actually happening on the seafloor and in the negotiating rooms deciding its fate. Matthew spent years as a commercial fisherman, including five years as a deep sea trawlerman off the Central California coast, before moving into ocean conservation with Greenpeace International and eventually co-founding the DSCC to fight destructive bottom trawling on seamounts. That history shapes...

5,000 New Species Prove the "Ocean Desert" Deep Sea Mining Claim Is Wrong
How To Protect The Ocean
In September 2021, Time magazine profiled Gerard Barron, CEO of The Metals Company (TMC), and his push to mine the Clarion Clipperton Zone (CCZ), a stretch of international seabed between Hawaii and Mexico. In that profile, Barron called the CCZ "the most desert-like place on the planet," arguing that mining the deep sea does less environmental harm than mining a rainforest because there's supposedly so little life down there to disturb. That single line has been repeated for years as justification for deep sea mining. Andrew puts it to the test. The science tells a very different story. A...
info_outlineA grad student faces a simple choice: write another term paper, or take a summer internship. She takes the internship, gets assigned to sea turtles, and thirty years later she is in the room for some of the most consequential ocean policy agreements ever negotiated. This episode traces that career from the beginning, and it starts with a realization that shapes everything that follows: sea turtles do not read maps. They cross every border humans have drawn, which means protecting them requires countries to cooperate, not compete.
Andrew walks through the arc of this career step by step. It starts with an anthropology degree and a grad-school detour into public policy, an internship with an NGO in Washington, D.C., then called the Center for Marine Conservation, and a growing understanding that migratory ocean species force international cooperation whether countries want it or not. From there the story moves through the State Department, more than a decade on international tuna negotiations, and eventually a role at the International Sustainable Seafood Foundation (ISSF). Along the way, Andrew connects the story to his own winding path from marine biology researcher to ocean communications manager, and makes the case that careers in ocean conservation rarely move in a straight line.
This episode kicks off a five-part week on How to Protect the Ocean. Tuesday looks at corals nearly as old as the pyramids and the fight to save them. Wednesday covers the High Seas Treaty and the moment the gavel dropped. Thursday breaks down seafood policy and what retailers need to know about what shoppers actually want. Friday brings the full interview with the person at the center of this week's story.
Takeaways:
- Careers in ocean conservation rarely move in a straight line. This one started with choosing an internship over a term paper and grew into three decades of international policy work.
- Migratory species that ignore national borders, like sea turtles, are the practical reason international cooperation and multilateral ocean agreements exist at all.
- Green sea turtle populations are showing real improvement, a genuinely hopeful data point inside an episode that's otherwise about policy and negotiation.
- This is episode one of five leading into Friday's full interview with the guest whose career this episode traces.
