Episodes
What Happens When Politicians Ignore Ocean Science?
Ocean conservation is often treated like an impossible problem, but the truth is simpler: when strong laws are created, enforced, and guided by science, ocean protection works. In this episode of How to Protect the Ocean, Andrew Lewin looks at the unglamorous but powerful role of legislation in ocean conservation. From Canada's Oceans Act and marine protected areas to the U.S. Endangered Species A
Canada's Ocean Promise Sounds Big, But Is It Enough?
Canada has a rare chance to become a global ocean conservation leader, but the path is not simple. In this episode of How to Protect the Ocean, Andrew Lewin breaks down Canada's proposed $3.8 billion nature strategy, what it could mean for marine protected areas, and why ocean protection matters as development pressures grow. From pipelines and shipping to offshore oil and gas, fisheries conflicts
Are We Protecting the Ocean Fast Enough?
The world has now protected about 10% of the ocean, a major milestone compared to where we were a decade ago. But with the global 30x30 target aiming to protect 30% of land and ocean by 2030, the big question is whether we are protecting the right places, fast enough, and with enough enforcement to make those protections real. In this episode, Andrew breaks down why 10% ocean protection is worth c
What Happens When People Show Up for the Planet
Many people feel powerless when it comes to environmental issues. Whether it's climate change, habitat destruction, or controversial development projects, it can seem like the biggest decisions are made without public input. But recent protests against proposed AI data centers are reminding us that communities still have influence when people choose to get involved. Across North America, residents
The Ocean Connection We Are Losing, And Why It Matters
Ocean conservation often focuses on threats: climate change, overfishing, plastic pollution, deep-sea mining, and political failure. But on World Ocean Day, this episode takes a step back to ask a deeper question: why do we protect the ocean in the first place? I reflect on the emotional, cultural, and personal connections people have with the ocean, from living near the coast to watching whales,
What You Think About Cold Water Oceans Is Probably Wrong
Cold water oceans do not always get the same attention as coral reefs and tropical beaches, but they are full of incredible life, beauty, and ecological importance. In this episode of How to Protect the Ocean, Andrew Lewin speaks with Kirsti Burnett about why cold and temperate marine ecosystems deserve more love, curiosity, and protection. From Nova Scotia's eelgrass beds and coastal inlets to bl
How One Puddle Can Hold an Entire Ocean World
Tide pools may look like simple puddles along the shoreline, but they are tiny ocean ecosystems filled with fish, crabs, snails, sea stars, worms, algae, and other hidden marine life. In this episode of How to Protect the Ocean, Andrew Lewin explains why tide pools are one of the best ways to experience the ocean without a boat, scuba gear, or expensive equipment. These small pools reveal how much
Why Canada Matters to the World's Largest Sea Turtle
Leatherback sea turtles are usually associated with warm tropical beaches, but some of the world's largest sea turtles travel thousands of kilometers to cold Canadian waters each year. Why? Jellyfish. In this episode of How to Protect the Ocean, Andrew Lewin explains why Atlantic Canada is an important feeding destination for leatherback sea turtles, how cold water ecosystems support huge bursts o
The Shark That Turns Fear Into Fascination
Blue sharks are one of the most beautiful and misunderstood predators in the ocean. In this episode of How to Protect the Ocean, we explore how this sleek, cold water shark can change the way people think about sharks, especially when they see one off the coast of Atlantic Canada. Blue sharks travel enormous distances, follow ocean conditions, and play an important role in healthy marine ecosystem
The Cold Water Fish That Looks Dead, But Isn't
Ocean sunfish are one of the strangest fish on Earth. They can look like a giant floating dinner plate, drift sideways at the surface, and appear almost lifeless, but their strange behaviour is part of an incredible survival strategy. In this episode of How to Protect the Ocean, Andrew Lewin explores why the mola mola, also known as the ocean sunfish, spends time in cold Canadian waters. These wat
How Do You Protect an Ocean Nobody Owns?
High Seas Treaty | Ocean Governance | Marine Protection How do you protect an ocean that belongs to everyone and no one at the same time? In this episode of How to Protect the Ocean, Andrew Lewin speaks with Rebecca Hubbard, Director of the High Seas Alliance, about one of the most important ocean agreements in history: the High Seas Treaty. The high seas cover nearly half of Earth's surface and c
The Hidden Fight Behind the High Seas Treaty
The High Seas Treaty took nearly 20 years to negotiate, not because countries disagreed that the ocean matters, but because ocean protection becomes much harder when money, power, access, and fairness are involved. In this episode of How to Protect the Ocean, we look at why protecting the high seas is so politically difficult. From industrial fishing fleets and marine genetic resources to enforcem
Will the High Seas Treaty Actually Change Anything?
High Seas Treaty implementation is now the real test for ocean conservation. The agreement was historic, but the hardest part was never getting countries to celebrate the deal. The real challenge is what happens after the headlines disappear. In this episode of How to Protect the Ocean, Andrew Lewin looks at whether the High Seas Treaty can actually change anything for biodiversity beyond national
Can High Seas Protected Areas Actually Work?
High seas protection sounds powerful, but can marine protected areas actually work thousands of kilometres from shore? In this episode of How to Protect the Ocean, Andrew Lewin breaks down why creating protected areas beyond national waters is historic, but also incredibly difficult. The episode explores the difference between paper parks and real protection, why enforcement matters more than most
Who Actually Owns the Ocean?
High seas conservation matters because nearly half of the planet lies beyond any one country's control. In this episode of How to Protect the Ocean, we ask a deceptively simple question: who actually owns the ocean? Andrew breaks down what the high seas are, why international waters have historically been treated like a free-for-all, and why that approach no longer works in a world of industrial f
What Happens If Canada Runs Out of Forage Fish?
Forage fish may be small, but they hold Canada's ocean food web together. In this episode of How to Protect the Ocean, Andrew Lewin speaks with Jack Daly, marine scientist at Oceana Canada, about the new report Little Fish, Big Foundation and what it reveals about the state of forage fish across Canada. These tiny fish, including capelin, herring, mackerel, sardines, and anchovies, feed whales, se
The Tiny Fish Holding the Ocean Together Are at Risk
Small fish like sardines, anchovies, herring, and capelin may not get much attention, but they quietly power entire ocean ecosystems. In this episode of How to Protect the Ocean, we explore why forage fish are some of the most important species in the sea and how climate change could disrupt the food web in ways scientists are only beginning to understand. As oceans warm and ecosystems shift, the
The Tiny Fish Whales Cannot Live Without
Forage fish are some of the most important animals in the ocean, but most people barely know they exist. Sardines, anchovies, herring, capelin, and other small schooling fish support whales, seabirds, salmon, tuna, and commercial fisheries. In this episode of How to Protect the Ocean, Andrew Lewin explains why forage fish are often overlooked, why their abundance matters more than people realize,
What Happens When We Fish the Ocean's Food Supply?
Forage fish may be small, but they help hold the ocean food web together. Species like sardines, anchovies, herring, capelin, and sand lance feed whales, seabirds, salmon, cod, tuna, and many other predators. In this episode of How to Protect the Ocean, Andrew Lewin explains why fishing these small fish for fishmeal, fish oil, aquaculture feed, livestock feed, pet food, and supplements can create
The Tiny Fish Holding the Ocean Together
Forage fish may be small, but they help power the entire ocean food web. Species like sardines, anchovies, herring, capelin, and sand lance feed whales, seabirds, tuna, salmon, and many other marine predators. In this episode of How to Protect the Ocean, Andrew Lewin explains why these overlooked fish matter so much, what happens when they decline, and why industrial fishing, climate change, and w
Why Ocean Nonprofits Keep Struggling to Raise Money
Ocean conservation funding is one of the biggest challenges facing nonprofits today. In this episode of How to Protect the Ocean, Andrew Lewin speaks with nonprofit consultant James Misner about why so many mission-driven organizations struggle to raise money, even when their work is urgent and important. James explains why grants alone are not enough, why donors need to see the human connection b
The People Saving the Ocean Are Burning Out
Ocean conservation is often framed as hopeful, inspiring, and mission-driven. But behind the scenes, many scientists, advocates, educators, and communicators are dealing with burnout, financial instability, emotional exhaustion, and the pressure to stay optimistic while ocean problems keep getting worse. In this episode of How to Protect the Ocean, we look at the emotional cost of trying to save t
Why Good Ocean Science Still Doesn't Lead to Action
Ocean science can tell us what is happening to marine ecosystems, fisheries, climate impacts, and protected areas, but that information does not always reach the people who need it most. In this episode of How to Protect the Ocean, Andrew Lewin looks at the communication gap between researchers, policymakers, media, industry, and the public. The problem is not always a lack of science. Often, it i
Are Ocean Scientists Becoming Fundraisers Just to Survive?
Ocean conservation depends on science, but what happens when marine scientists spend more time chasing funding than doing the research itself? In this episode of How to Protect the Ocean, we look at the hidden financial pressure behind ocean conservation. Research vessels, field expeditions, monitoring programs, satellite tools, underwater robotics, staff, permits, and long-term analysis all cost
Why Saving the Ocean Still Runs Out of Money
Ocean conservation is a global effort worth billions, so why do so many marine scientists, nonprofits, and conservation groups still feel like they are constantly running out of money? In this episode of How to Protect the Ocean, Andrew Lewin breaks down why ocean conservation often operates grant to grant, donation to donation, and year to year. He explains how unstable funding affects marine pro
Are We Paying to Damage the Ocean?
Bottom trawling is one of the most common fishing methods in the world, but what if it costs society more than it earns in profit? In this episode of How to Protect the Ocean, we look at a recent study on bottom trawling in Europe that found the total societal costs can be far higher than the profits generated, in some cases up to 90 times higher. Much of that hidden cost comes from carbon release
Can We Study the Ocean Without Harming It?
Ocean research helps us understand marine life, but what happens when the tools we use to study animals disturb the very creatures we are trying to protect? This episode looks at a powerful question in marine science: can we study the ocean without harming it? Whale sharks and other marine animals are often studied using tools like tags, drones, boats, and tracking technology. These methods can re
Are We Ignoring the Best Climate Solution We Already Have?
Blue carbon could be one of the most powerful climate solutions we already have, so why is it still missing from so many climate plans? In this episode of How to Protect the Ocean, we look at how mangroves, seagrasses, salt marshes, and other coastal ecosystems store carbon, protect coastlines, and support ocean health. Ocean climate solutions are often treated as secondary to land-based actions l
Why Healthy Whales Are Suddenly Ending Up on Beaches
Whale strandings are heartbreaking, but what happens when the whales are not sick? In this episode of How to Protect the Ocean, we look at a recent mass pilot whale stranding in Scotland, where many of the animals appeared to be healthy before they ended up on shore. Pilot whales are highly social animals, which means one wrong turn can become a disaster for the entire pod. As prey shifts closer t
Why Sea Cucumbers Matter More Than You Think
Sea Cucumbers are disappearing in parts of the ocean, and most people have no idea why that matters. These strange, soft-bodied animals might not look important, but they play a critical role in keeping marine ecosystems healthy and functioning. Ocean Ecosystems rely on sea cucumbers to recycle nutrients, clean sediments, and support the balance of life on the seafloor. When they are removed throu
The Ocean Agency You've Never Heard Of, But Depend On Every Day
NOAA affects your daily life more than you think, from the weather forecasts you check to the seafood you eat, yet most people have no idea how important it really is. In this episode, we break down what NOAA actually does, why it matters for your safety, food, and environment, and what could happen if funding cuts weaken its ability to operate. Ocean science plays a critical role in predicting hu
Why Ocean Exploration Could Matter to Your Future More Than You Think
Ocean exploration may sound like a niche science topic, but it affects far more than research ships and submarines. If most of the ocean remains poorly mapped and rarely observed, how can we protect habitats, predict hazards, discover new species, or understand climate change? In this episode, we break down why exploring the ocean still matters right now. NOAA ocean science plays a major role in u
What Does NOAA Have to Do With Saving Marine Wildlife?
NOAA marine wildlife protection affects whales, sea turtles, dolphins, seals, and endangered ocean species in ways most people never see. In this episode, we break down how one agency helps prevent extinctions, protects habitats, responds to strandings, and enforces laws that keep marine wildlife alive. Ocean conservation is not only about beach cleanups or personal choices. It also depends on sci
Why Your Seafood Depends on NOAA More Than You Think
NOAA seafood safety affects more than most people realize. The seafood in your grocery store or on your restaurant plate may rely on NOAA science, inspections, fisheries data, and monitoring systems that help keep oceans productive and supply chains accountable. In this episode, we break down why this often-overlooked agency matters to everyday consumers. Seafood traceability is not just about lab
What Happens If Weather Warnings Start Failing?
NOAA helps protect millions of people before hurricanes, floods, tornadoes, and tsunamis hit, but most people never realize how much they rely on it. In this episode, we break down the hidden systems behind weather forecasting, emergency alerts, and disaster preparedness, and why cuts to NOAA could have consequences far beyond the ocean. Natural Disasters are becoming more intense in many regions,
Who Decides What Happens to the Ocean?
Who really controls the future of the ocean, and why does progress so often feel slow? In this episode, Andrew speaks with Sarah Federman about the hidden systems behind environmental harm, corporate accountability, and why everyday people are often left carrying decisions they never made. You'll learn why protecting the ocean is bigger than personal choices, how public pressure can create tipping
What Actually Forces Companies to Protect the Ocean?
Most people think companies change because they care. That is rarely how it works. In this episode of How to Protect the Ocean, we break down what actually forces companies to stop harming the ocean, and why awareness alone is often not enough. Ocean Conservation pressure can come from many places: lost customers, public campaigns, employee pushback, investor concern, regulation, or personal wake-
We Protected the Ocean, So Why Are We Going Backwards?
Ocean Conservation felt like it was moving forward, so why does it suddenly feel like everything is being undone? In this episode, Andrew Lewin breaks down why environmental progress rarely happens in a straight line, and why setbacks do not always mean failure. If you have felt discouraged by policy rollbacks, delayed protections, or repeated fights over the same issues, this episode is for you.
Why You Feel Guilty About Problems You Didn't Create
Why do simple choices like buying groceries, using plastic, or ordering dinner feel so loaded? In this episode of How to Protect the Ocean, we unpack the hidden systems that push environmental responsibility onto consumers instead of solving problems where they start. If you've ever felt guilty trying to "do the right thing," this episode is for you. Consumer choices matter, but they were never me
The System That Makes Ocean Problems Feel Like Your Fault
Caring about the ocean should feel meaningful, so why does it often feel exhausting instead? In this episode, we unpack why so many people experience eco-anxiety, ocean overwhelm, and the sense that nothing they do matters. You'll learn why "do your part" messaging can backfire when collective problems are treated like personal failures. More importantly, you'll hear what research and real-world
What Happens in Antarctica Affects You More Than You Think
Antarctica may feel distant, frozen, and disconnected from everyday life, but what happens there can shape sea level rise, ocean circulation, climate systems, and the future health of marine ecosystems around the world. In this episode of How to Protect the Ocean, part of the Surfacing Secrets: Explore the Ocean, Know the Planet series with Ocean Networks Canada, we go behind the scenes of an inte
The Hidden Risk Behind Melting Glaciers
Antarctic glaciers are melting, but the real story is not just about ice disappearing. It is about what happens next, and how fast those changes can impact sea levels, coastlines, and ecosystems around the world. Glacier collapse is not a slow, steady process. In some cases, it can happen rapidly, triggered by warming oceans, weakening ice shelves, and shifting climate patterns. Scientists are now
What Happens When Emperor Penguins Lose Their Ice
Emperor Penguins are facing a problem most people don't fully understand, and it's happening faster than expected. In this episode, we break down what's really happening in Antarctica as sea ice disappears beneath emperor penguin colonies. These penguins rely on stable ice to breed, raise chicks, and survive, but warming oceans and changing climate patterns are making that ice less reliable every
What You Think About Leopard Seals Is Probably Wrong
Leopard seals are often seen as one of the most dangerous predators in Antarctica, but what if that story is incomplete? Leopard seals play a critical role in the Antarctic food web, influencing populations of penguins, fish, and even other marine mammals. Their behavior, hunting patterns, and distribution are shaped by sea ice, climate change, and shifting ecosystems. Yet despite their importance
What Orcas Are Changing in Antarctica Might Surprise You
What if Antarctica isn't changing as slowly as we think? And what if one of the biggest drivers of that change… is an animal most people only see as a top predator? In this episode, we look at what orcas are really doing in Antarctica, and why it might surprise you. These aren't just whales passing through a frozen landscape. They are specialized hunters with learned behaviors, working in coordina
Why 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 o
Who 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 bet
Why 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 negotiation
How 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, t
The 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 understand
The Ocean Career Path Nobody Talks About
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 opportun
Why Ocean Jobs Look Great, Until You Actually Start One
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 eno
You Have the Skills, So Why Is Nobody Hiring You?
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 mo
What'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
Most Ocean Jobs Aren't Posted, So How Do People Get Them?
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, wh
How Business and Storytelling Are Changing Ocean Conservation
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 scalabl
Why 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, relatabilit
Why 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.
Ocean 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
Why 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
Why 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,
The 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.
Why 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 t
The 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, endanger
The 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 specie
The 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
Can 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
Ocean 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
The 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
Ocean 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 influ
What 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, ma
We Know How to Protect the Ocean. So Why Aren't We Doing It?
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 ecosyst
The Ocean Just Got a Historic Deal. Will It Actually Protect Your Future?
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 q
The Ocean Is Visible Now, What Happens Next Is Up to Us
The ocean is no longer invisible. Satellites can now track fishing vessels across the planet in near real time. So if we can see the exploitation, what happens next? In this episode of How to Protect the Ocean, we break down how satellite monitoring, AIS tracking, radar systems, and machine learning have fundamentally changed ocean enforcement. Industrial fishing now covers more than half of the o
The Ocean Is "Protected." So Why Is Illegal Fishing Still Happening?
Marine protected areas now cover more than 8 percent of the global ocean. Governments announce new boundaries. Press releases celebrate historic milestones. But here is the uncomfortable truth: a line on a map does not stop illegal fishing. In this episode, we break down why enforcement, not designation, is the real driver of ocean recovery, and why many so called protected areas still struggle wi
Nature, Law and the High Seas: Can Direct Action Save the Ocean?
Nature is protected by laws on paper, but what happens when those laws are not enforced? On the high seas, beyond national borders, illegal fishing, whaling, and environmental exploitation often operate in legal gray zones. Environmental lawyer and author Sarah Levy joins the show to unpack how international ocean law actually works, where it fails, and why enforcement remains the biggest challeng
Nature Is Overheating: Ocean Heat Records Are Breaking Again
Nature is absorbing more heat than we realize, and most of it is going into the ocean. Global ocean heat content has reached record highs, confirming what climate scientists have warned for years: the ocean has absorbed more than 90 percent of the excess heat trapped by greenhouse gases. Data from NOAA and findings summarized in the IPCC AR6 report show a continued upward trajectory, with no sign
Nature's Most Overlooked Climate Solution: How Seagrass Is Quietly Saving Coastal Economies
Seagrass meadows may be the most powerful climate solution underwater, and almost no one is talking about them. Research published in Nature Climate Change shows that seagrass ecosystems store vast amounts of carbon in their sediments, sometimes for centuries. Unlike forests, much of this carbon is locked below ground in oxygen poor environments, reducing the risk of rapid release. But when seagra
Ocean Fish Populations at Risk: How WTO Subsidies Still Fuel Overfishing
Ocean fish populations are under pressure, and public money is still part of the problem. The World Trade Organization adopted a Fisheries Subsidies Agreement to curb harmful funding tied to illegal fishing, but major loopholes remain. Billions of dollars in government support continue to prop up industrial fleets that contribute to overcapacity and overfishing. Research published in Nature estima
Atlantic Fish Stocks at Risk? Politics Pushes Industrial Fishing Expansion
Atlantic fish stocks sit at the center of a new political push to expand commercial fishing in federal waters. A recent U.S. executive action signals increased access for industrial fleets, raising critical questions about how economic policy aligns with science based fisheries management. The United States promotes its fisheries system as one of the most sustainably managed in the world, built on
