Red Tide, Decoded: Why It Isn't Random, and How to Track It
How To Protect The Ocean
No smell. No warning. Just a beach full of people who start coughing at the same time, grab their towels, and leave. That's red tide, and it feels completely random until you know what's actually happening in the water. Karenia brevis, the algae behind it, produces a toxin called brevetoxin that rides the wind and waves into the air along the shoreline, which is why people can start coughing with no visible sign anything's wrong. The 2017 to 2019 Southwest and Southeast Florida bloom cost the region an estimated $2.7 billion, mostly in tourism losses, and it wasn't a freak event. Follow the...

Nature's Kidneys: How Coastal Wetlands Stop Ocean Pollution
How To Protect The Ocean
Green water. A smell that won't go away. Sometimes, dead fish washing up on shore. That's what too much nitrogen does to a coastline, and it's easy to hear stories like this and feel like the ocean is just losing. This episode is the opposite of that. Here's what most people don't know: a healthy stretch of marsh or mangrove can pull nitrogen straight out of the water before it ever becomes a problem. A single restored 100-acre wetland cut nearby ammonia by 62 percent and total nitrogen by 37 percent, and saved local water systems about $17,000 a year, all within three years. Then there's...

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...

Regulations and enforcement in the swim-with-whale tourism industry are crucial for protecting humpback whales and ensuring tourist safety. The incident discussed in the podcast episode highlighted the potential dangers of close interactions between humans and humpback whales during swim tours. The humpback whale carrying a person out of the water demonstrated the unpredictability of these interactions and the need for stricter regulations.
The episode emphasized the importance of establishing clear guidelines and rules for swim-with-whale activities to prevent disturbances to humpback whales. Research conducted by ecologists, including Stephanie Stack, indicated that the behavior of humpback whales was significantly altered during swim tours, leading to disruptions in their resting patterns and overall behavior. These disturbances could have negative implications for the well-being of the whale population and the sustainability of marine tourism.
To address these concerns, it was suggested that the Queensland government should implement stronger regulations and enforcement measures for swim-with-whale tours. Currently, there appears to be a lack of specific laws governing these activities, leaving room for operators to potentially overlook important safety and conservation protocols. Strengthening regulations would not only protect humpback whales from potential harm but also ensure the safety of tourists participating in these immersive experiences.
Furthermore, the episode highlighted the need for collaboration between whale-watching companies, scientific researchers, and conservationists to develop comprehensive codes of conduct for swim-with-whale tours. By establishing industry-wide standards and promoting adherence to these guidelines, operators can minimize disruptions to humpback whales and create a safer environment for both the animals and tourists.
In conclusion, the podcast episode underscored the urgency of enhancing regulations and enforcement in the swim-with-whale tourism industry to safeguard humpback whales and promote responsible marine tourism practices. By prioritizing the well-being of these majestic creatures and implementing stringent guidelines, stakeholders can work towards creating a sustainable and ethical environment for human-wildlife interactions in the marine realm.
Humpback whales can be disturbed by human interactions, impacting their behavior and potentially affecting their population recovery. The episode highlights an incident in Australia where a humpback whale carried a person out of the water during a swim-with-whale tourism activity. This interaction, although seemingly harmless as the person was unharmed, can have significant consequences for the whales.
Research conducted by ecologists, including Stephanie Stack, has shown that commercial swimming with whale tours can lead to disturbances in humpback whale behavior. The study found that the whales made direct changes when swimmers were in the water, and the whales did not resume undisturbed behavior even after the swimmers exited the water. This disruption can have negative implications for the whales, especially since humpback whales are capital breeders with limited energy reserves.
Furthermore, the study revealed a 50% reduction in the proportion of time that whales spent resting during swim tours compared to whale watch tours. This reduction in resting time can impact the overall health and well-being of the humpback whale population. It is crucial to minimize disturbances to humpback whales to ensure their continued population recovery and the sustainability of the marine tourism industry.
The episode emphasizes the need for robust education, enforcement programs, and continued monitoring of humpback whale populations to mitigate the impacts of human interactions. Regulations and enforcement of these rules are essential to protect humpback whales from disturbances caused by swim-with-whale activities. By understanding and addressing the potential negative effects of human interactions on humpback whales, we can work towards ensuring the conservation and recovery of this species.
Collaboration between operators, scientists, and government officials is crucial for the development and implementation of effective regulations for swim-with-whale tours. In the podcast episode, it was highlighted that the incident involving a humpback whale carrying a person out of the water raised concerns about the impact of swim-with-whale tourism on humpback whale behavior.
Stephanie Stack, a researcher studying whale tourism impacts, emphasized the need for robust education, enforcement programs, and continued monitoring of population dynamics through scientific research to minimize negative impacts on humpback whales. She conducted a study in Hervey Bay where the whale-watching fleet developed their own code of conduct for swim tours, indicating a proactive approach by operators in response to research findings.
The episode also mentioned the importance of strengthening and enforcing existing regulations to ensure the safety of both humans and whales during these interactions. It was noted that while regulations exist, there is a need for additional rules to address specific scenarios, such as maintaining adequate distances and respecting whale resting times.
By fostering collaboration among operators, scientists, and government officials, a comprehensive set of regulations can be developed that considers the well-being of humpback whales and the safety of tourists. Operators can benefit from scientific insights to enhance their practices, while government officials can ensure that regulations are effectively enforced to protect marine wildlife.
Overall, the episode underscores the significance of multi-stakeholder collaboration in creating sustainable and responsible swim-with-whale tours. By working together, these parties can address the challenges posed by such activities and strive towards a harmonious coexistence between humans and humpback whales in their natural habitat.
