A New PBS Documentary Wants You to Care About Coral. Meet the Man Behind It.
How To Protect The Ocean
A new documentary called Descent – Into the Blue starts airing on public television stations nationwide on September 1, 2026. It's narrated by Peter Coyote, directed by Rory Fielding, and one of its central voices is Mike Goldberg, co-founder of the Florida Keys coral restoration nonprofit I.CARE and owner of Key Dives in Islamorada. Andrew sits down with Mike for the full, unedited version of the conversation this week's four solo episodes have been building toward: 30-plus years running a dive shop, more than 10,000 dives, and a front-row seat to watching the reefs he built his life around...

Show Me the Receipts: Why I.CARE Monitors Every Coral It Plants
How To Protect The Ocean
Most coral restoration groups check on a sample of what they've planted, often around 20 to 30 percent, and report that sample as if it represents everything in the water. I.CARE checks on all of it. Every single coral outplant gets monitored at one week, one month, 90 days, then one, two, and three years, with no substitute and nothing left unaccounted for. That rule was built in by co-founders Mike Goldberg and Dr. Kylie Smith before I.CARE ever planted its first coral, and Mike frames it as a matter of fiduciary duty, the same obligation he'd expect from anyone handling someone else's...

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...
info_outlineMike 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, around 2017 into 2018, a young woman walked into his shop just to fill a couple of scuba tanks. She turned out to be Dr. Kylie Smith, a PhD student studying the relationship between parrotfish populations and coral outplants nearby. By the time she left, Mike had asked her a dozen questions. She kept coming back, and he kept asking more, in what he calls his own "period of discovery." It took roughly a year to find direction, and part of that year was Mike convincing Kylie not to take a government job and instead co-found a nonprofit with him, something her own family saw as risky. In this episode, Andrew walks through how that unlikely partnership, her science and his three decades of local hustle, became I.CARE (Islamorada Conservation and Restoration Education): a nonprofit that planted its first coral in January 2021, now runs its own onshore nursery, and partners with Mote Marine Laboratory, Reef Renewal USA, the Florida Aquarium, and the Reef Institute.
This is episode two of a four-part week built around Andrew's interview with Mike Goldberg, co-founder of I.CARE. Monday's episode covered the global state of coral reefs and the case for restoration; this episode is Mike's own story before his full interview airs Friday.
Takeaways:
- I.CARE didn't start with a grant or a strategic plan. It started with a dive shop owner's frustration and one chance conversation with a grad student who walked in to fill some tanks.
- The disease that pushed Mike to act, Stony Coral Tissue Loss Disease, isn't like bleaching. It's an unresolved, contagious, tissue-killing outbreak that's been spreading through Florida and the wider Caribbean for over a decade with no confirmed cause.
- The partnership worked because it paired two kinds of expertise that don't usually sit in the same room: a scientist's research and a small business owner's community connections and hustle.
- Mike spent part of a year talking Kylie out of a safer path (a government job) and into co-founding a nonprofit instead, a real risk her own family flagged at the time.
- Watching your own livelihood visibly decline, and choosing to act instead of walking away, is its own kind of origin story, separate from the science.
