Blue Nitrogen: The Nutrient Story Coastal Wetlands Have Been Hiding
How To Protect The Ocean
Every time this podcast talks about coastal wetlands, the conversation goes straight to carbon. Marshes, mangroves, and seagrasses pull carbon dioxide out of the atmosphere and lock it in soil for centuries, and that story has earned coastal ecosystems a real seat at the climate table. Dr. Adam Langley, a global change ecologist and professor of biology at Villanova University and a research associate at the Smithsonian Environmental Research Center, thinks there's a second story hiding in that same soil that could matter just as much, or more: nitrogen. Langley and 37 co-authors just...

Who Pays for Plastic? Inside the Law Quietly Shifting the Bill to Producers
How To Protect The Ocean
For decades, the honest answer to "who pays to deal with plastic packaging once it leaves the shelf" was taxpayers, quietly, through municipal budgets that funded garbage trucks and recycling plants running at a loss, whether or not the packaging actually got recycled. That's the system extended producer responsibility (EPR) is built to replace: a legal requirement that the companies making and selling packaging fund what happens to it after a customer buys the product, not the city that collects it afterward. Seven US states have now passed packaging EPR laws. Oregon has been charging...

Inside Ocean Conservancy's Fight to Make Washing Machine Filters the Law
How To Protect The Ocean
Ocean Conservancy's "Not Safe for Wash" campaign is built around a simple premise: the fix for washing machine microfiber pollution already exists, so the fight isn't about inventing new technology, it's about forcing a nearly two-decade-old idea into law. Its own May 2026 poll of 1,010 Americans found concern about microplastics up 32% since 2023, nearly 9 in 10 people concerned, and 81% in favor of requiring filters on new washing machines. The public isn't the obstacle. The real opponent is AHAM, the Association of Home Appliance Manufacturers, the trade group representing the companies...

Your Washing Machine Sheds Up to 18 Million Microfibers a Load
How To Protect The Ocean
Every wash cycle sheds plastic. Last Monday, Andrew talked with Dr. Anja Brandon of Ocean Conservancy about microfiber pollution, and one question from that conversation stuck with him: has anyone actually fixed this yet? In this solo follow-up, Andrew traces a microfiber's actual path, from the moment agitation, heat, and detergent work it loose from a shirt, through the drain, into a wastewater treatment plant, and out the other side into biosolids, farmland, rivers, and the ocean, with a growing body of research suggesting some of it ends up in human lungs and even in the human placenta....

Can Bacteria Actually Eat Plastic?
How To Protect The Ocean
Bacteria that eat plastic sounds like the fix everyone's been waiting for, and Andrew gets sent videos about it constantly. So on this solo episode, following Monday's interview with Dr. Anja Brandon of Ocean Conservancy, he goes looking for the real state of the science. The short version: it's promising, it's roughly a decade of real research deep, and it is nowhere close to running at the scale the ocean plastic crisis actually needs. The bacterium that started this whole field, Ideonella sakaiensis, was discovered breaking down PET plastic in Japan in 2016. A 2025 breakthrough from NREL,...

The 90 Percent Fix Hiding in Your Laundry Room
How To Protect The Ocean
Every time you run a load of laundry, your washing machine sheds plastic. Not metaphorically: synthetic clothing made from polyester, nylon, and rayon releases microfibers with every wash, and depending on the study, a single load can shed anywhere from a few hundred thousand to millions of them. Most of us have never thought about it, because unlike a plastic bag on the beach, you can't see it happening. In this episode, Andrew talks with Dr. Anja Brandon, Director of Plastics Policy at Ocean Conservancy, about the plastic pollution problem hiding in plain sight behind the more familiar...

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,...
info_outlineBetween 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 these bodies actually meet, and how governance decisions travel from those negotiating rooms toward your dinner table. That includes the International Seafood Sustainability Foundation (ISSF), whose work spans science-based fisheries management, advancing improved fishing practices, transparency and verification tools like annual company audits and public vessel tracking, and policy engagement with RFMOs, and the Marine Stewardship Council (MSC), whose certification functions as an eco-label with real financial weight behind it, including why MSC pulled its certification of the Maine lobster fishery twice, in August 2020 and again in December 2022.
The throughline is that ISSF and MSC are complementary but distinct approaches to the same goal, not two steps in a single pipeline. ISSF works across science, fishing practice, transparency, and RFMO policy; independent conformity assessment bodies, not ISSF, assess fisheries against the MSC standard. This episode sets up tomorrow's interview with an ISSF representative who has spent decades inside these negotiations and will walk through what that cooperation actually looks like in the room.
Takeaways:
- A regional fisheries management organization (RFMO) is a treaty-based body that turns "we should manage this fishery responsibly" into an enforceable, multi-country agreement.
- Eco-labels like MSC certification carry real financial weight. Losing one can force a fishery to change its practices, even when the science on the underlying risk is still ambiguous.
- ISSF's work spans science-based fisheries management, improved fishing practices, transparency and verification, and RFMO policy engagement, not just company audits and vessel tracking.
- ISSF and MSC are complementary but distinct: independent conformity assessment bodies, not ISSF, assess fisheries against the MSC certification standard.
- Per ISSF's 2025 audit-period report, participating companies achieved 98.8% aggregate conformance across 32 conservation measures (their tenth consecutive year above 90%), and PVR-registered vessels showed 75.6% aggregate compliance on vessel-specific conservation measures. These are two separate transparency metrics covering different populations, not a before-and-after comparison.
