S1 Ep 1911Why Tuna Might Be Doing Better Than You Think
Tuna fisheries are often seen as one of the biggest challenges in ocean conservation. But that story is starting to change, and most people have not caught up to it yet. In this episode, you'll hear how tuna fisheries in many parts of the world are actually improving. Better science, stronger monitoring, and more coordinated international management are helping rebuild stocks and reduce pressure on key species. To understand what's really happening, I spoke with Susan Jackson, President of the International Seafood Sustainability Foundation. She shares how data-driven decisions, harvest rules, and industry collaboration are changing the way tuna is managed globally. But progress does not mean the job is finished. Some stocks are still under pressure, and continued effort is critical to keep things moving in the right direction. This episode breaks down what's working, where challenges remain, and why tuna fisheries may be one of the most important examples of how ocean conservation can succeed when science and policy align.

S1 Ep 1910Who Decides How Much Fish Ends Up on Your Plate?
Most people assume fisheries are either working or failing, but very few people know how the system actually works. In this episode, I break down the hidden process behind fishing limits, stock assessments, political negotiations, and the science that shapes what ends up on your plate. You will learn why fisheries management can go wrong, what happens when countries ignore the science, and how better systems like harvest rules and stronger accountability can help fisheries recover. This episode also sets up tomorrow's interview with Susan Jackson from ISSF, where we will reveal just how far tuna fisheries have come.

S1 Ep 1906Why the Tuna on Your Plate Didn't Run Out
Tuna sustainability might be the biggest ocean success story you've never heard about. Nearly 100 percent of global tuna catch is no longer experiencing overfishing, but that didn't happen by accident. There is a hidden system behind the scenes that most people never see, and it is quietly changing how fisheries work around the world. Harvest rules for fisheries are replacing political negotiations with science-based decisions. Instead of arguing every year about how much fish to catch, managers now use pre-agreed rules that respond automatically to changes in fish populations. This shift has helped tuna stocks recover and stay stable, even as global demand continues to grow. Ocean conservation solutions are often criticized for failing, but tuna shows what happens when science, industry, and policy align. In this episode, you will learn how this system works, why it matters for the seafood you eat, and what it tells us about the future of ocean protection. 👉 Follow the show to get daily ocean insights that connect science to real-world impact.
S1 Ep 1908How Do We Know If Tuna Is Running Out?
Tuna fishing is a global industry, but how do we actually know if we're catching too much? Every time you eat tuna, you're relying on a system most people have never heard of: stock assessments. These scientific models estimate how many fish are in the ocean, how fast they reproduce, and how much can be caught without causing long-term damage. Stock assessments are not about counting every fish, they're about making the best possible decisions with imperfect data. Scientists use catch records, fishing effort, and biological information to understand whether tuna populations are healthy or at risk. But the science is only part of the story. In this episode, we break down how tuna stock assessments work, why they are critical for sustainable seafood, and how organizations like ISSF help ensure that decisions are based on science, not just politics. You'll also learn how past failures shaped today's system, and why the future of tuna depends on getting these calculations right. 👉 Follow How to Protect the Ocean for daily ocean science insights.

S1 Ep 1907The Tuna Story Nobody Is Really Talking About
What if one of the most popular seafoods in the world isn't the disaster story you've been told? Tuna has been at the center of overfishing conversations for decades. But something changed, and most people have no idea. In this episode, we unpack the hidden system behind tuna fishing, how it nearly failed, and what turned it around. This isn't about saying everything is fine. It's about understanding what actually worked, why it worked, and what it means for the future of ocean conservation. Because if tuna can improve, it raises a bigger question: Why isn't every fishery doing the same? 👉 Follow How to Protect the Ocean for your weekday ocean science updates.

S1 Ep 1904What's Really Stopping You From Starting an Ocean Career
A lot of people think the path into ocean conservation is simple: get the degree, get the experience, then get the opportunity. But that is not how it works for many people anymore. In this episode of How to Protect the Ocean, I talk about why waiting for permission, waiting to feel ready, or waiting for someone to teach you everything first can quietly kill momentum before your career even begins. I break down the myth that credentials alone will open doors, the real skills employers and collaborators notice, and why building proof of your abilities matters more than saying you are passionate. If you want to work in ocean conservation, marine science communication, policy, data, or research support, this episode will help you think differently about how careers actually get built. Because the people getting noticed are often the ones who start before they feel ready.

S1 Ep 1901Why Facts Fail and Stories Save the Ocean, The Science of Changing Human Behavior
Ocean storytelling is not just communication, it is a conservation tool. Why do people ignore climate data, overfishing statistics, and coral reef loss, even when the science is clear? In this episode, we break down the psychology behind why facts alone fail to drive action, and how storytelling can bridge the gap between knowledge and behavior. You will learn how emotional connection, relatability, and narrative framing influence real-world ocean conservation outcomes. Science communication is evolving, and the ocean depends on it. We explore real examples like the UN's "Don't Choose Extinction" campaign and visual storytelling from SeaLegacy, alongside insights from climate communication research. This episode shows how effective storytelling can increase engagement, inspire action, and reshape how the public connects with ocean issues like overfishing, coral bleaching, and biodiversity loss. If you care about protecting the ocean, this episode will change how you communicate. Whether you are a scientist, conservationist, or ocean advocate, you will walk away with practical strategies to make your message resonate and drive impact.
S1 Ep 1900Why Ocean Solutions Fail Without Collaboration (And How to Fix It)
Ocean conservation solutions often fail, not because the science is wrong, but because the right people aren't working together. In this episode of How to Protect the Ocean, we break down why collaboration between scientists, businesses, and policymakers is essential to solving today's biggest ocean challenges. Ocean collaboration is already transforming conservation, and the results are powerful. Using real-world examples like Global Fishing Watch, you'll learn how satellite data, artificial intelligence, and policy advocacy came together to expose illegal fishing on a global scale. We also explore how cross-industry partnerships are influencing policy, unlocking funding, and accelerating real-world impact. Ocean solutions depend on people who can connect science, business, and policy. Whether you're an early-career scientist, a conservationist, or someone interested in protecting the ocean, this episode will help you understand how meaningful change actually happens and how you can be part of it.

S1 Ep 1899Ocean Startups Are Changing Conservation Faster Than Science Alone
Ocean conservation is no longer driven by science alone, startups are stepping in to turn ideas into real-world solutions at scale. In this episode, we explore how companies like Coral Vita and Running Tide are accelerating reef restoration and experimenting with ocean-based carbon removal, bringing speed, funding, and innovation into a space that has traditionally moved slowly. Ocean startups are reshaping how solutions are built, tested, and scaled. You will learn how these companies combine science, business models, and emerging technologies to tackle coral bleaching, climate change, and ecosystem loss. We also break down the risks, including overpromising, ecological uncertainty, and the need for strong governance to guide innovation. Ocean solutions are evolving quickly, and understanding where startups fit into conservation could change how we approach protecting marine ecosystems.

S1 Ep 1895Why Ocean Solutions Fail, And How Business Can Actually Save the Ocean
Ocean conservation is failing to scale, and it's not because of a lack of science. In this episode, we break down why decades of ocean research have not stopped overfishing, pollution, and habitat loss, and what is really holding solutions back. Ocean solutions need more than discovery, they need adoption. You'll learn how business models, financial incentives, and scalable systems are the missing link between scientific breakthroughs and real-world impact. We explore why many conservation efforts stall, and what separates small successes from global change. Ocean innovation is already happening, and it's changing the game. From nutrient capture systems that turn pollution into profit to scalable environmental solutions, this episode shows how aligning economics with conservation can drive faster, larger impact than traditional approaches.

S1 Ep 1897Why You Should Think Twice Before Eating Squid (The Seafood Labeling Problem No One Talks About)
Squid fisheries are booming worldwide, but most consumers have no idea what they are actually eating. In this episode, marine biologist and Oceana policy advisor Marine Cusa breaks down how seafood labeling gaps are hiding critical information about squid species, origins, and fishing practices. Using DNA testing, her team uncovered that many squid products come from distant, high-risk fisheries, often without any transparency for consumers. We explore how traceability failures, unregulated fishing, and complex global supply chains make squid one of the hardest seafood products to track. You will also learn how some fisheries are linked to illegal fishing and poor labor conditions, and why current labeling laws in North America and Europe are not enough. If you care about sustainable seafood, ocean conservation, and making informed choices, this episode will change the way you look at calamari forever. 👉 Follow the podcast to stay informed on ocean science and conservation.

S1 Ep 1896The Squid You Eat Is a Mystery, Seafood Mislabeling Explained
Seafood mislabeling is more common than most people realize, and squid might be one of the biggest examples. When you order calamari, you are rarely told which species you are actually eating. With more than 300 squid species in the ocean, and most products labeled simply as "squid," consumers are left with almost no information about the origin, sustainability, or even the species on their plate. Squid fisheries are growing rapidly across the globe, but they are also some of the hardest to track. Squid is often caught on the high seas, processed in multiple countries, and sold in forms like rings or frozen mixes that remove all identifying features. This creates major gaps in traceability and opens the door to mislabeling, illegal fishing, and supply chain confusion. Ocean conservation depends on transparency, and squid shows exactly where the system breaks down. In this episode, we break down why squid is so difficult to trace and what that means for seafood sustainability. Tomorrow, we continue the conversation with marine scientist Marine Cusa, who studies seafood traceability and global squid fisheries.

S1 Ep 1895Why Seafood Traceability Is Broken (And What's Really on Your Plate)
Seafood is one of the most globalized food systems in the world, but that complexity comes at a cost: traceability. In this episode of How to Protect the Ocean, we break down why it is so difficult to track seafood from the moment it is caught to the moment it reaches your plate. With supply chains spanning multiple countries, processing steps that remove identifying features, and practices like transshipment happening far from oversight, even well-intentioned systems struggle to keep up. We explore how seafood moves through a complex network of fishing vessels, cargo ships, processing plants, and distributors, and why information is often lost along the way. You will also learn about the tools scientists and regulators are developing to solve this problem, including DNA barcoding, satellite monitoring, and digital catch documentation systems. If you have ever wondered whether the seafood you are eating is what it claims to be, this episode will give you the clarity you need to understand the system and its challenges.

S1 Ep 1894The Fish on Your Plate Might Not Be What the Label Says
What if the fish on your plate isn't the fish you think it is? Scientists around the world have been testing seafood from grocery stores, markets, and restaurants using DNA. The results are often surprising. Studies have found that anywhere from 10 percent to more than 30 percent of seafood products are mislabeled. In some cases, cheaper fish are sold as expensive species. In other cases, endangered fish or illegally caught seafood can enter the market under completely different names. Seafood mislabeling is not just a consumer problem. It can hide illegal fishing, undermine sustainable fisheries, and make it harder for regulators to protect ocean ecosystems. In this episode, we break down how common seafood fraud really is and why it matters for the future of ocean conservation. Follow How to Protect the Ocean for weekday ocean science updates.

S1 Ep 1893The Seafood Label Problem Most Shoppers Never Notice
Most seafood labels look simple, but they often hide more than they reveal. When you buy fish at a grocery store, the package might say salmon, tuna, or cod. But those market names can represent dozens of different species, and the label rarely tells you exactly which one you are eating. In many cases, key details like the fishing location, the vessel that caught the fish, or the specific species are missing. In this episode of How to Protect the Ocean, we explore the seafood labeling gap and why it matters. When multiple species are grouped under the same market name, it becomes harder to detect seafood fraud, track fisheries, and ensure sustainable seafood choices. Understanding what labels do and do not tell us is an important step toward improving transparency in the global seafood supply chain.

S1 Ep 1892The Invisible Climate Engineers Running Our Ocean
Ocean microbes quietly power the planet. In this episode, we explore the microscopic organisms that regulate Earth's climate, produce much of the oxygen we breathe, and move enormous amounts of carbon through the ocean every day. These invisible life forms are not just background players in the ocean system; they are central to how the planet works. Synthetic biology is now pushing this idea even further. Dr. José Ángel Moreno-Cabezuelo, a synthetic biologist working in Oxford, is engineering ancient microorganisms called cyanobacteria to capture carbon dioxide using sunlight and biology. His work shows how living systems could become part of the climate solutions we desperately need. Science communication is another major theme of this conversation. After years working inside the scientific system, Dr. Moreno-Cabezuelo began questioning why so much scientific knowledge fails to connect with society. Through his book Heartbeats of Consciousness, he explores the intersection of biology, neuroscience, philosophy, and the human experience, asking a powerful question: if science understands life so well, why does it still struggle to help us understand how to live it? Listen to learn how microbes shape our planet, how biotechnology may help tackle climate change, and why clarity in science might be one of the most important tools we have for protecting the ocean.

S1 Ep 1891Can Engineered Ocean Microbes Help Fight Climate Change?
Engineered microbes could transform how we fight climate change. Scientists are modifying ancient ocean microorganisms to capture carbon dioxide and produce materials using only sunlight and seawater. These tiny organisms may become living factories capable of creating fuels, plastics, and industrial chemicals without relying on fossil fuels. Cyanobacteria are at the center of this research. These photosynthetic microbes helped oxygenate the Earth billions of years ago, and now scientists are exploring how they can be engineered to produce biofuels, biodegradable plastics, and sustainable industrial compounds. Synthetic biology is opening the door to manufacturing systems powered entirely by sunlight and carbon dioxide. Synthetic biology could reshape how humanity produces materials. If these microbial systems scale successfully, they could reduce emissions from the chemical and plastics industries while capturing carbon from the atmosphere. But engineering living systems also raises questions about safety, environmental impacts, and responsible oversight. Listen to the full episode to learn how ocean microbes could become one of the most powerful climate tools scientists are developing.

S1 Ep 1890Ocean Microbes That Eat Oil and Pollution
Millions of people see the damage caused by oil spills and plastic pollution, but very few know what happens beneath the surface. In the ocean, microscopic organisms begin responding almost immediately. Certain marine microbes can actually consume hydrocarbons and other pollutants, turning toxic compounds into energy. Ocean microbes play a surprising role in pollution cleanup. After the Deepwater Horizon oil spill, scientists observed massive blooms of oil degrading bacteria that rapidly multiplied as they fed on hydrocarbons released into the water. These microbes act as nature's chemical recyclers, breaking down pollutants and helping ecosystems recover. In this episode, we explore how marine microbes break down oil, what scientists learned from major spills, and whether these organisms could help tackle future pollution problems. While microbes can help mitigate damage, they also reveal the limits of nature's ability to absorb human pollution. Share this episode.
S1 Ep 1889The Ocean Engine That Regulates Earth's Climate
Every year, the ocean removes billions of tons of carbon dioxide from the atmosphere. Most people assume whales, mangroves, or seagrass are responsible for this massive climate service. But the largest carbon capture system on Earth is actually microscopic. In this episode of How to Protect the Ocean, we explore the biological carbon pump, a powerful process driven by ocean microbes that captures carbon at the surface and transports it deep into the ocean for centuries. These tiny organisms, including phytoplankton and cyanobacteria, form the foundation of marine food webs and play a critical role in regulating Earth's climate. Without them, atmospheric CO₂ levels could be dramatically higher. We break down how this microbial system works, why it matters for climate stability, and how warming oceans could disrupt one of the planet's most important natural carbon storage mechanisms. Understanding the ocean's smallest organisms might be the key to understanding our planet's climate future.

S1 Ep 1888Ocean Microbes Run the Planet — Here's Why That Matters
When people think about ocean life, they imagine whales, sharks, coral reefs, and giant kelp forests. But the vast majority of life in the ocean is invisible. In a single teaspoon of seawater, there can be millions of microbes, including bacteria, archaea, and microscopic phytoplankton. These organisms may be tiny, but collectively they regulate oxygen production, drive nutrient cycling, and influence Earth's climate system. In this episode of How to Protect the Ocean, we explore the hidden microbial world that powers the ocean. You will learn how ocean microbes control the chemistry of seawater, support marine food webs, and even help regulate the global climate. We also look at a major blind spot in ocean conservation. While most policies focus on protecting whales, sharks, and coral reefs, the microbial systems that keep the ocean functioning are rarely considered in marine protection strategies. Understanding ocean microbes may be one of the most important scientific frontiers for protecting the ocean in a changing climate.

S1 Ep 1887What Do House Cats Have to Do With Deep-Sea Mining? A Surprising Ocean Connection
Deep sea mining and domesticated cats do not seem like they belong in the same story… but they are. In this episode of the How to Protect the Ocean Podcast, Andrew Lewin sits down with deep-sea ecologist Dr. Andrew Thaler to explore one of the most unexpected stories in ocean science. What starts with mining minerals from the deep ocean quickly turns into a journey through ancient trade routes, maritime history, and the surprising role the ocean may have played in how cats became one of humanity's closest animal companions. Dr. Thaler shares a fascinating narrative that connects deep-sea resources, seafaring civilizations, and the spread of cats across the world. It is a reminder that the ocean has influenced human history in ways we rarely think about, and that even modern debates like deep-sea mining are connected to much bigger stories about exploration, trade, and human society. If you enjoy ocean science, unusual scientific connections, and great storytelling, this episode will give you a completely new way to think about both the deep ocean and the animals that now live in our homes. Listen now to discover how an ocean story thousands of years in the making might explain why cats and humans share such a unique relationship.
