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. B...

Ocean careers often look straightforward from the outside, but the reality is far more complicated. In this episode, Andrew flips the script and shares what actually happened behind the scenes as he landed his latest role, including the uncertainty, tradeoffs, and decisions most people never see. Career paths in ocean conservation are rarely linear. From networking to timing to unexpected opportunities, this episode breaks down how jobs really happen in this field and why chasing the “perfect j...

A lot of people dream about working in ocean conservation, but far fewer talk about what it takes to actually stay in the field. In this episode, Andrew breaks down why so many careers in ocean conservation burn out, from low pay and short-term contracts to emotional exhaustion and unstable funding. You’ll hear the truth about the three major career paths in the field, why passion alone is not enough, and how building transferable skills, multiple income streams, and your own platform can help ...

You got the degree. You built some skills. Maybe you even started networking. So why does getting that first real job in ocean conservation still feel nearly impossible? In this episode of How to Protect the Ocean, I break down the real reason so many early career ocean professionals get stuck. I talk about the experience trap, how to rethink what counts as experience, why small projects matter more than people realize, and how strategic volunteering can either help your career or waste your ti...

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 colla...

If you’ve been applying for ocean conservation jobs and hearing nothing back, this episode is for you. Too many people think opportunities come from polished resumes and endless job applications. In reality, many careers in ocean science and conservation are built through trust, familiarity, and real relationships. In this episode, Andrew breaks down the hidden job market in ocean conservation, why cold applications often fail, what networking actually means, where to build connections in this ...

Ocean conservation is changing, and science alone is no longer enough. In this episode, Andrew Lewin speaks with Peter Simek, CEO of EarthX, about how business, investment, and storytelling are shaping the future of environmental solutions. They discuss why collaboration across industries is critical, how market-driven innovation is accelerating impact, and what it takes to turn ideas into scalable solutions. If you want to understand how ocean protection actually happens in the real world...

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...

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 i...

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 ...

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 effo...

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 fi...

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 tra...

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 e...

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...

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 ...

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 a...

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 e...

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 multip...

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, ...

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 m...

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...

We Know How to Protect the Ocean. So Why Aren’t We Doing It? We do not have an ocean knowledge problem. We have an implementation problem. The science behind fisheries recovery, pollution control, climate adaptation, and high seas governance is strong and repeatedly confirmed. When fishing pressure is reduced, stocks rebuild. When nutrient runoff is controlled, water quality improves. When ecosystems like mangroves and seagrass are restored, coastlines stabilize. The evidence is not unclear. The...

High Seas Treaty: Nearly half the planet lies beyond national borders, and for decades it has operated under fragmented rules and weak oversight. Now, countries have agreed to a historic global deal to protect biodiversity in international waters. It sounds like a turning point. But a signed agreement does not automatically stop illegal fishing, deep sea extraction, or weak enforcement. The real question is whether this treaty will move protection from paper to practice. BBNJ Agreement: The new...
