Distant water fishing fleets are operating just beyond national borders, pulling massive amounts of squid from the ocean with almost no rules, and this episode asks a simple but urgent question: can the new high seas treaty stop ecological collapse before it is too late? Off the coast of Argentina, hundreds of vessels gather in international waters to exploit a regulatory loophole, threatening a keystone species that supports whales, seabirds, and entire food webs. What happens here does not stay here, it affects global fisheries, biodiversity, and the seafood on our plates.

High seas squid fishing has exploded in recent years, with satellite data showing fishing effort increasing dramatically while oversight remains weak. In this episode, I break down how squid fuel marine ecosystems, why their short life cycle makes them especially vulnerable, and how unregulated fishing in places like Mile 201 puts the entire South Atlantic at risk. I also explain what the new high seas treaty actually does, what it cannot do, and why enforcement and political will matter more than headlines.

High seas treaty 2026 is often described as historic, but one surprising and deeply emotional insight from this episode is that the treaty does not automatically stop overfishing. It creates a toolset, not a safety net. Without coordinated action, transparency, and pressure on distant water fleets, the ocean could continue to be emptied in plain sight, even under a new global agreement.

Hidden costs of seafood are shaping the global tuna industry in ways most people never see, and this episode asks why it matters for the ocean, workers, and anyone who buys seafood. Hidden costs of seafood raise a simple but uncomfortable question: if an industry cannot survive without public money, can it truly be sustainable, and who is paying the price behind the scenes?

Tuna fishing subsidies are at the center of this story. Drawing from new peer-reviewed research, this episode breaks down how fuel tax exemptions and government support keep European tuna fleets operating, even when they run operational losses. Without these subsidies, many fleets would struggle or collapse, revealing an economic model that depends on taxpayers while fishing pressure on the ocean continues.

Sustainable seafood myths are challenged by one surprising and emotional insight from this episode: some tuna fleets appear profitable on paper while actually losing money every year without subsidies, meaning the public absorbs the financial risk while ecosystems and fishing communities absorb the consequences. This changes how we should think about sustainability, accountability, and what responsible seafood really means.

This ocean place will help protect the planet but it is disappearing faster than scientists can track it, and that puts climate goals, food security, and coastal protection at risk. In this episode, we explore why seagrass meadows are one of the most powerful and overlooked ecosystems on Earth, and why failing to measure them properly could undermine global conservation and climate efforts.

Seagrass conservation and climate solutions are deeply connected, yet monitoring these underwater meadows has been inconsistent and fragmented around the world. We break down why scientists have struggled to compare seagrass data across regions, what an Essential Ocean Variable really is, and how standardizing measurements could transform how countries protect biodiversity and report climate progress.

Ocean biodiversity and blue carbon ecosystems reveal one surprising and emotional insight in this episode: despite storing massive amounts of carbon and supporting fisheries and livelihoods, seagrass often receives less protection than coral reefs or mangroves, largely because it is harder to see and harder to measure. Fixing that data gap could be one of the most effective nature-based climate solutions available today.

Ocean carbon sequestration is failing because we are ignoring one of the ocean’s most powerful climate allies, seaweed forests, and that blind spot could cost us precious time in the fight against climate change. This episode asks a simple but urgent question: how can one of the fastest-growing, most productive ecosystems on Earth still be missing from climate policy?

Seaweed blue carbon challenges everything we think we know about how the ocean stores carbon, because kelp forests do not lock carbon in place, they move it. Scientists are now tracking how seaweed captures carbon near the coast and exports it to the deep ocean, where it can be stored for centuries, yet conservation frameworks have not caught up with this science.

Kelp forests climate change reveals the emotional core of this story: we are losing ecosystems that protect biodiversity, support fisheries, and quietly help stabilize the climate, often without realizing their value until they are gone. The surprising insight is that seaweed may already be helping the climate far more than we give it credit for, but only if we choose to protect it.

How Scientists Detect Ocean Life is one of the biggest challenges in ocean conservation, because we cannot protect what we cannot see, measure, or even prove exists. How Scientists Detect Ocean Life using environmental DNA asks a powerful question: what if a simple bottle of seawater could reveal more species than divers, cameras, and nets combined, and what does that mean for how we protect the ocean?

Environmental DNA ocean monitoring is changing how scientists understand marine biodiversity, especially for rare, shy, or hard-to-detect species. In this episode, you will learn how tiny fragments of DNA left behind by fish can be collected, analyzed, and matched to species, revealing hidden ecosystems that were previously invisible to science. One surprising insight from this research is that eDNA often finds species scientists did not even know were present, exposing how incomplete our current monitoring really is.

Ocean conservation science depends on accurate data, and this episode explores why better detection tools lead to stronger marine protected areas, smarter management decisions, and earlier warnings when ecosystems are in trouble. This story is not just about new technology, it is about hope, because knowing what lives in the ocean gives us a real chance to protect it before it disappears.

Human Relationship with the Ocean begins with a simple but uncomfortable question: how did humanity become so disconnected from the very system that makes life on Earth possible, and why does that disconnection matter right now? This episode explores how the ocean is treated as a distant resource rather than a living, planetary force, and how that mindset shapes policy, economics, and everyday decisions that quietly accelerate ocean decline.

Ocean Literacy is more than knowing facts about marine life, it is about understanding how deeply human survival, culture, and identity are tied to the sea. A surprising and emotional insight from this conversation is the idea that many modern ocean problems are not caused by lack of science but by the stories we tell ourselves about separation from nature. When the ocean is framed as “out there” instead of part of us, protection becomes optional rather than essential.

Future of the Ocean depends on whether we can rebuild a meaningful relationship with the sea, one rooted in responsibility, humility, and shared fate. This episode challenges listeners to rethink progress, success, and stewardship, and offers a hopeful path forward by changing how we see our place within the ocean system, not above it.

Gulf Coast communities and oil drilling are once again at the center of a national decision, and the stakes could not be higher. A new US offshore oil drilling plan proposes expanded lease sales in the Gulf of Mexico, including areas close to Florida that many thought were protected. This episode asks a simple but urgent question: who benefits from these decisions, and who bears the long-term cost when something goes wrong?

Gulf of Mexico offshore drilling has a long history of environmental damage, economic disruption, and broken promises. Scott Eustis from Healthy Gulf explains how drilling threatens fisheries, tourism, coastal ecosystems, and the communities that depend on them. Drawing from science and lived experience, he connects today’s policy decisions to lessons learned from past disasters, including Deepwater Horizon, and explains why recovery is still not complete more than a decade later.

Protect the Gulf of Mexico is not just a slogan, it is a call grounded in science, justice, and community voices. One of the most surprising insights from this conversation is how some coastal communities that rely on clean water and healthy fisheries are excluded from decision-making, even though they face the greatest risks. This episode shows why offshore drilling is not just an environmental issue, it is a human one.

Should We Be Mining the Ocean Floor is a question that sounds futuristic, but the decisions are being made right now, quietly, and with consequences that could last for centuries. Governments and corporations are moving closer to extracting minerals from the deepest parts of the ocean, even though we barely understand the ecosystems that exist there or how damage might ripple through the planet.

Deep-sea mining risks go far beyond technology and minerals. This episode breaks down what deep-sea mining actually is, who is pushing it forward, and why international and US processes are advancing despite major scientific uncertainty and strong community opposition. One surprising and emotional insight from this episode is that some deep-sea ecosystems take millions of years to form, yet could be destroyed in a single mining operation, with no realistic way to restore them.

International seabed governance is at a turning point, and what happens next will shape how the ocean is treated for generations. You will learn who controls decisions about the ocean floor, why the United States is taking a separate and deeply concerning path, and what everyday people can do to slow this momentum and demand precaution before irreversible harm is done.

Listen to the full episode.

Coastal Economy and Tourism face a serious threat as the US government moves forward with a plan to open more than one billion acres of ocean to offshore oil and gas drilling, a decision that could impact beaches, fisheries, tourism jobs, and coastal communities for decades. This episode explains why this proposal matters now and how it could reshape life along the coasts of California, Alaska, and the Gulf of Mexico.

Offshore oil drilling is often framed as an economic benefit, but this conversation reveals a very different reality. Pete Stauffer from the Surfrider Foundation breaks down how tourism, recreation, and fishing support millions more jobs than oil and gas, and why a single spill can shut down beaches, fisheries, and local businesses for months or even years.

Ocean conservation becomes deeply personal in this episode when Pete shares how communities still feel the impacts of oil spills years later, including business owners who lost income, beaches closed for days, and volunteers stepping up to document pollution when official systems failed. The surprising truth is that offshore drilling is widely unpopular across political lines, and grassroots action has stopped similar plans before.

Wikie and Keijo Orcas are the last two captive orcas in France, and a major government decision may finally give them a path out of concrete tanks, but the clock is ticking. France has officially backed the Whale Sanctuary Project in Nova Scotia as their future home, yet this announcement does not mean an immediate rescue. In this episode, we break down what France’s move really means, what still has to happen, and why these two orcas remain in limbo despite years of public pressure.

Whale Sanctuary Project Nova Scotia represents one of the most ambitious attempts to move captive whales into a more natural ocean environment, but approval, funding, construction, and international permits all stand between promise and reality. We look closely at the remaining hurdles, including Canada’s regulatory role, the sanctuary’s readiness timeline, and why political support does not always translate into rapid action for animals already suffering.

France captive orcas have become a global symbol of the failure of marine parks to plan for animals once the shows end. One of the most emotional realities revealed in this episode is that Wikie has spent over two decades in tanks without ever experiencing the ocean, and her son Keijo has never known anything else. This decision could reshape the future of captive orcas worldwide, but only if it leads to real, urgent follow-through.

US oil and gas drilling is once again at the center of a high-stakes decision that could shape America’s coastlines, marine life, and coastal communities for decades. This episode asks a critical question: should the U.S. lock itself into new offshore drilling just as climate risks and ocean damage are accelerating, or is there still time to choose a safer path for the ocean and future generations?

Offshore drilling impacts go far beyond fuel production, and Oceana campaign director Joseph Gordon explains why oil spills are not short-term disasters but long-term crises. One of the most emotional insights from this episode is his description of oil spills as invisible clouds that marine mammals and cleanup workers are forced to breathe, causing health impacts that last decades after the headlines fade. These are consequences most people never see, but communities continue to live with.

Public comment offshore drilling still has power, even in difficult political moments. Joseph shares how bipartisan opposition has stopped similar plans before, why Florida, California, Alaska, and the Gulf of Mexico are on the front lines right now, and how everyday people can influence the final outcome. This episode breaks down what is at stake and why speaking up right now truly matters.

Deep sea hydrothermal vents reveal a hidden world where life thrives without sunlight, forcing scientists to rethink how ecosystems can exist in extreme heat, pressure, and darkness. Nearly two kilometers beneath the Pacific Ocean, superheated fluids erupt from the seafloor at Endeavour, creating environments that challenge everything we thought we knew about life on Earth and how it survives.

Deep-sea hydrothermal vents are not isolated deep ocean curiosities, they actively influence the chemistry of the entire Pacific Ocean. In this episode, scientists explain how minerals and iron released at Endeavour can be traced thousands of kilometers across the ocean, fueling productivity far from the vents themselves and connecting deep ocean processes to surface ecosystems in surprising ways.

Ocean Networks Canada enables this discovery through one of only two cabled deep-sea observatories in the world, allowing scientists to monitor volcanic activity, chemistry, and biodiversity in real time. This episode explores why Endeavour is one of the most important natural laboratories on the planet, what it teaches us about the origins of life, and how it may even help us understand life beyond Earth.

Surprising insight: the fluids released at Endeavour do not disappear into the ocean, they can be chemically traced across the entire Pacific, meaning deep-sea activity shapes ocean life on a planetary scale.

Climate Solutions for the Ocean are urgently needed as warming seas, biodiversity loss, and ecosystem collapse accelerate faster than most people realize, and one of the most powerful tools may be hiding just beneath the waves. In this episode, Andrew Lewin sits down with Scott Bohachyk, Director of Seaforestation at Ocean Wise, to explore how kelp forests function as underwater life support systems for the ocean, supporting fisheries, stabilizing coastlines, and helping ecosystems recover from climate stress.

Kelp forests have declined by up to 50 percent globally, with some regions losing more than 90 percent of their kelp after marine heatwaves and ecosystem imbalances. Scott explains how Ocean Wise is actively restoring kelp forests in British Columbia through hands-on seaforestation, partnerships with First Nations, innovative nursery techniques, and standardized monitoring that tracks biodiversity recovery and ecosystem health over time.

One of the most surprising insights from this conversation is that kelp restoration is not primarily about carbon credits or climate hype. Instead, the real win comes from rebuilding biodiversity and ecosystem resilience, with climate benefits becoming a powerful bonus rather than the sole goal. This shift in perspective reframes how we think about climate solutions and what truly works in the ocean.

Tree-Free Products are disrupting industries that have relied on the same wasteful materials for more than a century, and the shift is happening faster than most people realize. In this episode, we explore how Emerald Ecovations produces over 370 sustainable alternatives without cutting down a single tree, dramatically reducing carbon emissions, water use and ocean-bound pollution. Ralph Bianculli shares why legacy companies resist change and how younger decision-makers are pushing corporate purchasing toward genuine sustainability.

Sustainable business is more than a buzzword; it is the measurable impact behind everyday products. Ralph explains why some corporations save 7,000 to 8,000 trees every year simply by switching to tree-free materials. He also breaks down how soil protection, water reduction and raw material sourcing shape the environmental benefits of their products, and why education is often a bigger barrier than cost. 

Environmental impact reporting becomes the emotional centerpiece of this conversation when Ralph reveals how only a small percentage of consumers identify as environmentalists, yet almost anyone can be moved by seeing exactly how many trees, gallons of water, and pounds of carbon their decisions can save. That moment often turns reluctant corporations into sustainability leaders. 

Mass penguin die off explained, a crisis that wiped out ninety five percent of some African penguin colonies, raises a heartbreaking question: how does a thriving species fall to fewer than ten thousand breeding pairs and almost no one sees it happening? This episode uncovers the chain reaction that pushed an entire population toward collapse, from vanishing sardines to the brutal timing of the molt that left tens of thousands of penguins starving. One of the most emotional discoveries in the research was that more than sixty thousand penguins died simply because they did not have enough body fat to survive a three week fast.

African penguin population collapse reveals a deeper story about the ocean. Sardines and anchovies shifted out of reach as warming waters changed plankton patterns, leaving penguins stranded at colonies they could not abandon. Even as conservation groups step in with nest protection, rescues, and fishing closures, the core problem remains that the food web itself has moved. Without a return of sardine abundance, recovery is nearly impossible at scale.

The collapse of the ocean food web illustrates how fragile marine ecosystems can become when climate pressure and overfishing intersect. Listeners will learn why conservation helps slow the decline but cannot reverse it until prey returns, why projections warn of possible extinction in the wild by 2035, and what actions people can take right now to protect one of the most iconic seabirds on Earth.

Marine Wildlife Victory raises a powerful question: what does it take to finally protect some of the ocean’s most threatened giants, and why did it take this long? In this episode, you will hear how manta rays, devil rays, and several shark species faced years of intense pressure from overfishing and international trade, and why the world finally agreed they needed stronger protection. The emotional turning point comes when we uncover that manta ray gill plates were so valuable in global markets that populations were declining faster than conservationists could respond.

Shark Conservation reveals how Appendix II regulations helped stabilize some species but were not strong enough to stop the decline. You will learn how international demand for shark fins pushed species like hammerheads and threshers to the brink, and why Appendix I status is such a game changer. One of the most surprising insights is how early, modest protections actually proved the concept that stronger measures work, giving global leaders the justification they needed to upgrade these species to the highest level of protection.

Ocean Protection Efforts highlight where this victory fits in the bigger story. This isn’t just about sharks and rays; it is about a shift in how the world values marine wildlife. These new protections cut off the legal international trade that fueled decades of exploitation, giving these animals a real chance at recovery while ensuring local conservation efforts have a fighting chance.

Call to Action: Listen to the full episode.

Northern Right Whale crisis: For years, scientists and advocates have watched this critically endangered species decline due to ship strikes, fishing gear entanglement, and rapid ocean change. This episode asks a crucial question: Does the first population increase in years signal real recovery or just a temporary pause in a long-term crisis, and what must change now to keep that number rising?

Whale conservation stories: Oceana campaigner Nora Ives brings clear insights into how monitoring efforts and shifting whale behavior shape our understanding of their future. She explains how storytelling has become a powerful tool for connecting people with an animal most will never see in person. She also shares a moving moment from the field, the unexpected birth of a calf from an older mother, a surprising and emotional reminder that hope can appear when least expected.

Oceana advocacy: The episode explores vessel slowdowns, fishing gear solutions, and the policy gaps that still threaten these whales. Listeners will come away with a deeper understanding of what is working and what is urgently missing from the conservation conversation.

Supermarket tuna raises a disturbing question: What’s behind your canned tuna? In this episode, you uncover the hidden human cost of the global tuna industry, including the devastating story of fisherman Deby Putra Bunanda, whose health collapsed after months at sea supplying tuna for major supermarket brands. His experience reveals a deeper and darker truth about forced labor, long deployments without oversight, and the human suffering behind one of the world’s most common foods. The surprising emotional insight: Bunanda returned home barely able to walk or speak after seven months at sea.

Sustainable fishing sounds simple on a label, but the reality is far more complicated. We look at the environmental toll of industrial tuna fleets, from destructive fishing methods like FADs to the bycatch of sharks, turtles, and juvenile tuna. We examine why certification labels, including MSC, often fail to guarantee true sustainability or ethical labor practices. You will also hear how ISSF pushes the industry forward while still facing major limits in transparency and enforcement.

Ethical seafood is possible, but only if consumers know what to look for. This episode breaks down which labels matter, why “pole-and-line” and “troll-caught” tuna are safer choices, and how certain brands perform better on transparency than others. If you’ve ever wondered whether your tuna is truly sustainable or if the worker who caught it was treated fairly, this episode gives you the clarity you need.

Ocean crisis:

COP30 Belém exposed massive gaps in climate action, and the ocean will carry the burden. In this episode we break down the missing fossil fuel commitments, the weak climate finance language, and the two track political system that threatens to push ocean science into the background. These decisions matter because the ocean is already absorbing the heat and carbon that our climate system cannot handle. 

Climate justice:

Indigenous communities and coastal nations called for a stronger voice at COP30 but were pushed aside, even during protests inside the venue. One of the most surprising moments came when Indigenous leaders were removed from the room while speaking about losing their homes and food security, something never mentioned in the global headlines. 

Coastal restoration:

From seagrass meadows to mangroves and kelp forests, this episode explains why ocean based climate solutions are being ignored at the highest levels of global climate policy. You will hear how we can scale these habitats to remove carbon, restore ecosystems, protect communities from storms and sea level rise, and keep the ocean front and center in climate conversations. 

How Deep Sea Mining could permanently disrupt the ocean’s most important animal routes, and most people have never thought about it. This episode asks the critical question: what happens when mining operations collide with species that rely on vast migratory pathways to survive? We break down the science in a way that makes the stakes impossible to ignore, from whale communication and sea turtle navigation to seabird feeding routes and shark migrations.

Whales: Our guest, Dr. Andrew Thaler, explains how mining doesn’t just damage the seafloor. It sends noise, light, sediment, and pollution across the entire water column. The most surprising takeaway is that animals living near the surface could suffer major impacts from mining occurring thousands of meters below them, simply because their survival depends on calm, uninterrupted travel corridors. It turns the deep sea into a threat zone rather than a sanctuary.

Ocean conservation: This conversation exposes a major gap in global mining policy. The focus is always the seabed, but the species most at risk never go anywhere near it. That realization leads to a powerful conclusion: when we talk about protecting the ocean, we can’t just talk about the bottom. We have to protect everything that connects it from top to bottom.

Listen now to understand the full story.

Fish Farm Clean Up reveals the hidden reality beneath a quiet coastline in Methana, Greece, where a ghost fish farm left behind more than forty tons of plastic cages, nets, metal frames, pipes, and even sunken boats. What looked peaceful on the surface hid a toxic underwater scrapyard that had been breaking apart and polluting the Saronic Gulf for years.

Shocking Footage from this cleanup shows how abandoned aquaculture sites become long-term pollution hotspots. The divers, Healthy Seas Foundation, and the Athanasios C. Laskaridis Charitable Foundation worked together to cut, lift, tow, and haul massive amounts of debris out of the ocean, revealing how ghost farms threaten coastal ecosystems, fish habitats, and water quality.

Marine Conservation efforts like this show why cross-sector collaboration matters. From recycling nets into ECONYL yarn to educating local communities and cleaning beaches, this operation highlights how recovery, restoration, and better oversight must become the global standard for aquaculture waste.

Healthy Seas: https://www.healthyseas.org/

Whales don’t get cancer as often as you might expect, and in this episode you learn how the bowhead whale’s unique DNA repair system is helping scientists understand cancer prevention and healthy aging. This Arctic giant lives more than 200 years, grows to airplane size, and still avoids the runaway mutation patterns that lead to tumors in other species.

Whales don’t get cancer at high rates because their cells repair DNA damage with remarkable accuracy, and recent studies show that bowhead whales have powerful repair proteins like CIRBP that might someday guide cancer research. You will hear how this repair strategy works, why it matters for humans, and why protecting long-lived marine mammals also protects the scientific insights they carry.

Fish feed in aquaculture is at the center of a complicated global story that most people never hear about. In this episode, Andrew sits down with marine biologist and policy expert Marine Cusa to explore the hidden world of fishmeal, fish oil, feed ingredients, and the surprising connections between aquaculture, wild fisheries, West African communities, and even penguin populations in Antarctica. 

Marine breaks down what actually goes into the pellets fed to farmed fish, why transparency is lacking in the supply chain, and how her genetics research is uncovering the real species being used in fish feed. The conversation reveals why feed matters for sustainability, human nutrition, local livelihoods, and the future of aquaculture as demand for seafood continues to grow. Whether you’re new to the topic or already deep in fisheries science, this episode opens the door to a critical but overlooked part of marine conservation.

Orcas vs Great White Sharks is more than a dramatic headline—it’s a sign of how ocean ecosystems are shifting before our eyes. New drone footage shows orcas in the Gulf of California attacking and killing juvenile great white sharks in what scientists believe are nursery zones. The footage, captured in 2020 and 2022, reveals orcas flipping young sharks onto their backs, inducing tonic immobility, and surgically removing their livers—a precise and efficient hunting technique that may reshape predator-prey dynamics.

For years, scientists have known about great white shark nurseries, but what defines a “true nursery” has always been debated. These new observations raise deeper questions: Are orcas expanding their hunting grounds, or are juvenile sharks moving into new, warmer waters due to climate change? If orcas continue targeting young sharks, could this affect the recovery and stability of great white populations across the Pacific? In this episode, Andrew explores the science, the controversy, and what these interactions mean for the future of ocean conservation.

Seagrass meadows are among the most vital yet overlooked ecosystems on our planet. In this episode of How to Protect the Ocean, Andrew Lewin explores a new 19-year study from Moreton Bay, Australia, which shows that seagrass coverage and diversity are declining over time despite short-term recovery periods. This long-term research reveals that while short-term studies might show seagrass bouncing back after storms or floods, the bigger picture tells a story of gradual loss and ecological transformation.

The episode also highlights why this decline matters: seagrass meadows are nurseries for fish, homes for turtles and dugongs, and major carbon sinks that help buffer climate impacts. Andrew connects the findings to global conservation lessons and introduces The Seagrass Effect, a new project and podcast dedicated to sharing research, restoration stories, and action opportunities for protecting seagrass ecosystems worldwide.

Animals affected by climate change are showing us how fragile our ecosystems have become. In this episode of How to Protect the Ocean, host Andrew Lewin speaks with Dr. Helen Killeen, a marine ecologist whose research connects seabird reproduction to shifting ocean temperatures, prey diversity, and climate pressures across the northern hemisphere.

Animals affected by climate change, from seabirds in the Arctic to those in the Pacific, serve as living indicators of ocean health. Helen explains how changes in prey diversity and warming oceans disrupt seabird breeding success, what this means for food webs, and why protecting biodiversity can help stabilize marine ecosystems. She also shares her journey from high-school science teacher to marine researcher, revealing how curiosity and adaptability are essential traits for anyone working to protect our planet.

Marine Conservation Projects are driving real wins: green sea turtles downgraded to least concern in many regions, North Atlantic right whales showing a small but meaningful uptick, and a new vaquita calf sighting offering hope. In this episode I explain the common thread behind these stories, targeted local projects, science monitoring, and laws that actually get enforced, and I share practical ways you can support the people doing the work.

From night patrols that protect turtle nests to whale disentanglement teams and community programs in Mexico that replace gillnets, you will hear how volunteers, NGOs, scientists, and agencies are collaborating. I also share simple options for listeners, micro-donations, monthly support for field teams and students, and amplifying calls to action, so your contribution compounds over time.

Bill Gates and Climate Change have become a trending topic after the billionaire philanthropist argued that the world is too focused on cutting carbon emissions and not focused enough on improving human welfare. In this episode, I unpack what Gates said, why it caused such a reaction, and how his argument connects to decades of work in climate justice and climate equity.

Many climate justice organizations have long emphasized that people struggling with hunger, illness, or poverty cannot prioritize environmental action until their basic needs are met. Gates’s claim—that people fighting to survive won’t care about climate change—has reignited a long-standing debate: should the global focus be on saving people now or saving the planet long-term? I explore what this means for climate policy, philanthropy, and how we communicate solutions for ocean and human health together.

You’ll also hear how these conversations tie back to ocean conservation, coastal communities, and the delicate balance between adaptation, mitigation, and justice.

North Atlantic right whales have been teetering on the edge of extinction for decades, with fewer than 400 individuals left. But recent reports hint at a small sign of hope: the population may finally be stabilizing, or even slightly increasing. In this episode, Andrew Lewin explores what that really means.

Conservation efforts, from slower ship speeds to ropeless fishing gear, are starting to make a difference—but are they enough to ensure these whales survive? Andrew breaks down the latest science, the hard numbers from NOAA’s newest technical memo, and why every calf, especially every female calf, matters for the species’ future.

This episode balances realism and optimism, showing how policy, technology, and human compassion can still change the course for one of the ocean’s most endangered giants.

Art and Ocean Science are merging in ways that bring new life to marine research and conservation. In this episode of How to Protect the Ocean, host Andrew Lewin speaks with the creative minds behind Ocean Networks Canada’s “Surfacing Secrets” project, a groundbreaking collaboration where sculptors, theatre directors, and scientists explore how art can help people see, feel, and understand the ocean in fresh ways.

Ocean creativity takes center stage as guests share how sculpture can represent underwater sounds, theatre can transform data into emotion, and how cross-disciplinary partnerships bridge the gap between research and public engagement. This powerful exchange between artists and scientists reveals how creative storytelling can inspire empathy, foster curiosity, and spark action for the ocean.

Ocean connection drives every part of this episode, reminding us that art isn’t just a reflection of science, it’s a vital part of understanding our planet’s most mysterious realm, the deep sea.

Nova Scotia Whale Sanctuary has officially received provincial approval, marking a monumental step toward creating Canada’s first ocean refuge for retired whales. In this episode of How to Protect the Ocean, Andrew Lewin explains how this decision moves the Whale Sanctuary Project closer to reality, what challenges remain before the sanctuary opens, and why this could change the way the world cares for marine mammals.

Andrew also dives into how the Whale Sanctuary Project built the foundation for this historic milestone through years of environmental assessment, scientific planning, and local engagement. He reflects on his own experiences as a marine biologist and communicator, sharing why the sanctuary represents more than just a safe haven for whales—it’s a sign that humanity is learning to live in balance with the ocean once again.

AI and Water are more connected than most people realize. As artificial intelligence continues to expand, the data centres that power it are using millions of litres of water every day to stay cool. This invisible demand is creating ripple effects across our freshwater systems, and ultimately, our ocean.

In this episode, Andrew Lewin uncovers how AI’s explosive growth is reshaping global water use. From groundwater depletion and saltwater intrusion near coastal data hubs to desalination discharges harming marine life, the story goes far beyond servers and code. He breaks down how indirect energy use from AI contributes to ocean warming and acidification, revealing that every digital action has a hidden aquatic cost.

Andrew also explores innovative solutions—from recycled and non-potable cooling systems to closed-loop designs that dramatically reduce water loss. With growing global demand for AI, he highlights the urgent need for transparency, accountability, and smarter policy design to protect both freshwater and marine environments.

Green sea turtle conservation shows us what’s possible when people, policy, and passion align. Once nearly wiped out by overharvesting and habitat loss, the green sea turtle has made an inspiring recovery after decades of global protection. In this episode, Andrew Lewin shares a deeply personal story of encountering a turtle nest in Florida with his daughters and reflects on how that moment connects to today’s IUCN Red List update.

But while the turtle story offers hope, the latest report warns of darker trends. Arctic seals like the harp, hooded, and bearded seals are now at greater risk as melting sea ice robs them of essential habitat, and 61 percent of the world’s bird species are in decline due to deforestation, agriculture, invasive species, and climate change. Andrew breaks down how the balance between success and loss reveals both the fragility of nature and the power of sustained conservation.

This episode isn’t just about wildlife; it’s about people choosing to act. Andrew explains how individual and collective choices—from voting and policy advocacy to supporting community-based conservation—can determine which species recover and which fade away.

Coral reefs suffering from climate change are no longer a warning for the future, they are happening now. A landmark scientific report reveals that warm-water reefs have already passed a tipping threshold due to global heating, leading to widespread die-offs and threatening the biodiversity and coastal protection they provide. For the millions of people who depend on reefs for food and livelihoods, this is not just an ocean issue but a global crisis.

Global heating is pushing other critical systems — from ice sheets to the Amazon rainforest to the Atlantic Ocean circulation — closer to collapse. The danger is not only ecological, but social and economic, with cascading impacts on communities worldwide. Yet the report also emphasizes the possibility of positive tipping points: rapid shifts in renewable energy, sustainable practices, and collective action that could steer us toward a safer future.

In this episode, Andrew Lewin connects the science to lived experiences as a marine biologist and ocean communicator. He shares what these findings mean for the future of coral reefs, why every fraction of a degree of warming matters, and how each of us can contribute to turning the tide.

Madagascar Environment is at the center of this engaging conversation with Dr. David Ebert, a world-renowned shark scientist and co-host of Beyond Jaws. In this episode, we uncover the unique challenges and opportunities that Madagascar’s marine ecosystems face, from biodiversity conservation to the pressures of unsustainable fishing.

Shark science takes on a new dimension as Dr. Ebert shares his experiences conducting fieldwork in Madagascar and how these insights contribute to our global understanding of marine species. This episode brings together conservation, local community needs, and international collaboration to highlight why Madagascar’s environment plays a vital role in ocean health worldwide.

Vaquita stands as one of the rarest marine mammals on Earth, with fewer than 20 left in the wild. In this episode, we explore what the near-extinction of the vaquita teaches us about the future of sharks and why their survival is critical to the health of the ocean.

Sharks play an essential role in keeping marine ecosystems balanced, yet they face many of the same threats that doomed the vaquita: bycatch, overfishing, and weak enforcement. This episode dives into the parallels, the urgency of acting before it is too late, and how the loss of sharks would ripple into every part of our lives, from food security to coastal protection.

Mentors: climate change is hopeless—at least, that’s the message many young scientists are hearing from the people they were told to admire. But what if giving up isn’t the only option? In this episode, I respond to a heartfelt email from a marine science student who refuses to stay silent, even when senior scientists tell her that solutions to climate change are naive, misguided, or politically inconvenient.

Mentors: climate change is hopeless may be the mantra of a tired system, but this generation of scientists has grown up under the weight of ecological crisis—and they’re ready to do something about it. I share concrete advice for early-career changemakers who want to be bold, build community, speak truth to power, and help people understand real climate solutions despite institutional apathy. If you’re frustrated, fired up, and looking for a way forward, this one’s for you.

Jane Goodall transformed the way we understand animals, conservation, and our place in nature. In this special tribute episode of How to Protect the Ocean, I reflect on Dr. Goodall’s incredible legacy and what her life’s work teaches us about empathy, science, and hope. From living with chimpanzees in Gombe to influencing ocean storytelling today, her impact spans generations and ecosystems. Jane showed us that animals are not resources, but individuals with emotions, intelligence, and culture. She taught us to listen, to observe, and to act.

Jane Goodall’s work didn’t end with primates. Her vision of conservation included youth, community, and global collaboration. She helped shape marine and terrestrial protection efforts, inspired countless scientists (especially women), and changed how we use emotional connection to inspire action. Even at 91, she was on a speaking tour, still using her voice to make the world better. This episode unpacks what she gave us and how we carry that legacy forward especially in ocean conservation.

Explore the ocean floor is more than a scientific ambition, it is a global necessity. In this episode of How to Protect the Ocean, Andrew Lewin speaks with Tim Kearns, Executive Director of Map the Gaps, about the upcoming Ocean Floor Explorer conference in Victoria, BC.

Fighting overfishing with AI is transforming how we protect the ocean. A new study revealed that nearly half of all coastal marine protected areas (MPAs) showed fishing vessel presence, with many ships operating “dark” without AIS tracking. This means that even in places meant to be safe havens for biodiversity, industrial fishing has been creeping in unnoticed.

Satellites and artificial intelligence are changing that reality. By detecting untracked vessels and guiding patrols, this technology is already leading to arrests in Gabon, better enforcement in Palau, transparency in Chile, and effective oversight in the UK Blue Belt program. In this episode, I’ll break down the science behind the study, the risks remote MPAs face, and the real-world success stories that give us hope.

Indigenous relationships with the ocean reveal powerful ways of understanding stewardship, culture, and conservation. This episode highlights how Indigenous communities have long held knowledge that connects people with marine ecosystems, guiding sustainable practices and deep respect for biodiversity.

Indigenous relationships are also about resilience, as communities navigate challenges like climate change, resource extraction, and policy that often ignores traditional voices. By listening to these stories, we see how honoring Indigenous knowledge strengthens conservation efforts and creates opportunities for partnerships rooted in respect and reciprocity.

Indigenous relationships remind us that conservation is not just about science; it is about people, stories, and traditions that teach us how to protect the ocean for future generations.

Great white shark DNA is one of the most puzzling mysteries in marine biology. Recent research has revealed that despite being one species, great whites have split into three distinct genetic groups across the globe. What’s even stranger: their nuclear DNA and mitochondrial DNA tell conflicting stories, leaving scientists scratching their heads.

Shark philopatry—the tendency of females to return to their birthplace to give birth—adds another layer to this mystery. While philopatry has been well documented in species like lemon sharks and blacktip sharks, great whites show patterns that don’t neatly fit the rules. This episode unpacks how philopatry and DNA research intersect, why sharks defy easy explanations, and how these puzzles matter for conservation.

Shark conservation depends on solving these mysteries. If different populations are genetically distinct, protecting one region isn’t enough. By understanding how sharks move, breed, and adapt, we can build stronger policies, create better marine protected areas, and ensure these apex predators survive in a rapidly changing ocean.

Pacific Islands Heritage Marine National Monument: For over a decade, these waters stood as one of the largest no-take zones on Earth, safeguarding corals, fish, and migratory species. But on day one of his presidency, Donald Trump erased the U.S. commitment to 30x30 and soon after issued Proclamation 10918, opening parts of the monument to commercial fishing.

Marine conservation at risk: The rollback sparked lawsuits and reignited the debate over whether U.S. marine protections are too vulnerable to political swings. Just two weeks ago, a court overturned Trump’s proclamation on a technicality, reclosing the area to fishing. In this episode, we break down what happened, what’s at stake, and how the U.S. can rebuild trust in its marine conservation commitments.

The future of 30x30: We explore the tension between conservation science, fishing industry pressure, and fragile presidential protections. The conversation highlights why codifying protections into law may be the only way forward to safeguard biodiversity hotspots like Wake, Johnston, and Jarvis.

Less than 400 left — that’s how many North Atlantic right whales remain in the world. These critically endangered whales are at the center of an urgent conservation story, but how the media communicates about them plays a powerful role in shaping public awareness and action. In this episode of How to Protect the Ocean, Andrew Lewin sits down with Dr. Marcus Reamer, a new PhD graduate in science communication, to explore how newspapers and digital outlets covered right whale crises over the past decade.

Science communication emerges as a critical conservation tool, with Dr. Reamer sharing insights from his research on major publications like the New York Times, Washington Post, and LA Times. Together, they unpack why media coverage spikes during crises but fades when attention shifts elsewhere, and what this means for endangered species storytelling.

Whale conservation depends not only on data and science but also on the narratives shared with the public. This conversation highlights how media framing can help or hinder conservation literacy, and how improved communication can increase support for saving one of the world’s rarest whales.

Managing fishing vessels goes far beyond tracking where a boat is registered. In this episode, we dive into Oceana’s Beyond the Flag report to explore how large-scale fishing vessels are often flagged in one country but owned in another, creating dangerous loopholes that allow illegal, unreported, and unregulated (IUU) fishing to thrive. This legal and beneficial ownership opacity undermines ocean governance, drains resources from coastal nations, and hides the true power behind global fishing operations.

Managing fishing vessels transparently is essential for sustainable ocean futures. We discuss why more than 6,900 industrial vessels are shrouded in secrecy, how open registries like Panama and Belize fuel the problem, and what can be done to hold owners accountable. With solutions ranging from public vessel ownership databases to policy reform, this episode highlights how better transparency could transform fisheries management worldwide.

Plastic pollution in the ocean is no longer just an environmental issue—it’s a public health crisis and an economic threat. In this episode, I break down the latest updates from the UN negotiations on a global plastics treaty, explaining why the talks in Geneva this month could set the course for the next generation’s relationship with plastic. From production caps to industry lobbying, the fight over how to address the problem is as intense as ever.

Plastic pollution in the ocean also raises questions about equity, with developing nations calling for solutions that protect both the environment and their right to grow sustainably. I share shocking new research on how microplastics are showing up in human bodies, costing trillions in healthcare, and why activists believe this treaty is our once-in-a-lifetime opportunity to act.

How 5 billion sea stars died is a story that shook marine ecosystems along North America’s Pacific coast. This episode dives into the groundbreaking discovery of the bacterium Vibrio pectenicida, the pathogen responsible for sea star wasting disease, which decimated up to 90% of sunflower sea stars. We explore how the loss of these predators caused sea urchin populations to explode, leading to widespread kelp forest destruction, and what new recovery strategies—such as captive breeding, probiotics, and climate monitoring—could mean for the species and the habitats they support. By understanding the science and the solutions, we can help restore balance to one of the ocean’s most important coastal ecosystems.

Climate Crisis and Capitalism are at the heart of David Suzuki’s powerful message in this episode. In a candid and impassioned reflection, Suzuki warns that if we continue to prioritize politics and the economy over protecting the environment, we may as well give up on climate action. He challenges the cultural obsession with perpetual economic growth, critiques the short-sightedness of political cycles, and urges a fundamental shift in our collective priorities.

David Suzuki’s call for transformation is both urgent and inspiring. He advocates for placing the environment at the center of all decision-making, recognizing that our survival depends on living within ecological limits. Drawing on decades of experience as a scientist, broadcaster, and environmental activist, Suzuki encourages individuals to embrace systems thinking, reevaluate their relationship with nature, and demand more from leaders who treat the planet as expendable. This is a wake-up call that goes beyond environmentalism—it’s a call for a radical reimagining of our future.

Map the Deep Sea to protect what we don’t yet understand. In this episode, Andrew Lewin speaks with Tim Kearns from Map the Gaps, a global initiative working to close the knowledge gap beneath the waves. With over 75% of the seafloor still unmapped in high resolution, the ocean remains Earth’s final frontier—and unlocking its secrets is essential for biodiversity, disaster planning, and climate action.

Ocean mapping is more than bathymetry. It’s a tool for social justice, environmental stewardship, and informed decision-making. Tim shares how Map the Gaps supports small island nations, Indigenous communities, and global science efforts through collaboration and cutting-edge technology. From an exploration policy perspective, this conversation makes a clear case: mapping the deep sea is the foundation for a sustainable ocean future.

Shark Week 2025 opened with a spectacle that left many conservationists and shark advocates frustrated. The premiere episode, Dancing With Sharks, featured handlers hugging, hand-feeding, and even riding sharks—behaviors that distort shark biology and promote a dangerous misunderstanding of these wild animals. In this episode, we examine how the use of tonic immobility and forced interactions undermines shark conservation and sends the wrong message to the public.

Shark conservation deserves better than spectacle. Instead of relying on shock-value stunts, media like Shark Week should highlight real science, elevate expert voices, and promote respectful interactions with apex predators. We explore how better storytelling can change public perception and help build a future where sharks are protected, not exploited.

How to Protect Sharks isn’t just about banning shark finning or posting awareness videos. It’s about understanding what really works—supporting science-based policies, enforcing marine protected areas, backing local researchers, and stopping the spread of misinformation. In this episode, we clear up the confusion around shark conservation and focus on the actions that actually make a difference.

Shark conservation efforts must move beyond clickbait and into impact. From choosing ethical shark tourism operators to pushing for sustainable fishing reforms, this episode walks you through the most effective ways to help sharks and their ecosystems survive. Whether you’re a diver, educator, or ocean advocate, you’ll learn how to avoid the noise and support shark conservation that’s grounded in science and ethics.

How Marine Conservation Works is the foundation for protecting our oceans, but it’s often misunderstood. In this episode, we break down how marine conservation really happens—from grassroots community efforts and local fisheries management to scientific input and national policies. You’ll learn why effective conservation requires more than just good intentions—it takes collaboration, long-term planning, and strong social and political support.

Texas Flood 2025 revealed just how urgently we need smarter tools in disaster response. In this episode, Dave Jones, founder of StormCenter Communications, explains how his team used satellite imagery and real-time mapping to support emergency responders during the catastrophic floods. Their data helped identify stranded residents, blocked roads, and the areas most in need—turning science into life-saving action.

Satellite technology for disaster response is revolutionizing real-time crisis management. Dave shares how open-access Earth observation data, localized GIS tools, and close coordination with emergency services are building more resilient communities as climate change amplifies flood risks.

Conservation is about collaboration, and collaboration is what we are discussing today.

Ocean collaboration is at the heart of many conservation success stories, but what happens when it breaks down? In this episode of the How to Protect the Ocean podcast, host Andrew Lewin talks with Bart Oor, the founder of Balean, a platform created to support independent ocean conservationists by giving them the funding, structure, and digital tools to succeed. They dive into the barriers many changemakers face when working outside of traditional institutional channels and how a lack of communication and community support often holds back ocean progress.

Balean’s mission is to foster a decentralized, human-centered support network for ocean missions. Bart shares how his background in engineering led him to build Balean as a solution to the gaps he witnessed in ocean collaboration. This episode also reflects on Andrew and Bart’s own partnership and how aligned values and open communication can shape stronger ocean solutions. Whether you’re an early-career marine conservationist or a funder looking to empower grassroots initiatives, this conversation is a powerful call to action.

Orca Allokelping is the newly documented behavior where southern resident killer whales use bull kelp as a tool to rub against each other—possibly to remove dead skin and soothe irritation. Captured via drone, this social spa-like behavior, known as allokelping, reveals a rare example of cooperative tool use in the wild. Scientists believe it serves both physical and social functions, strengthening bonds within pods and supporting skin health.

Kelp grooming is more than just orca hygiene. It highlights the intelligence and cultural complexity of these endangered whales. The discovery comes with a reminder: kelp forests and Chinook salmon are essential for these behaviors to continue. As habitat and food sources decline, so too may the traditions that define this population. This episode breaks down the science behind the behavior and why it matters for conservation.

All The Sharks Netflix finally delivers what ocean lovers and science communicators have been asking for: a show that gets shark science right. In this episode, Andrew breaks down how the new game show sets itself apart from misleading content like SeaSpiracy and Shark Whisperer, and instead showcases real marine scientists, environmental journalists, and shark conservationists doing meaningful, ethical work.

Sharks have long suffered from misrepresentation in popular media, but All The Sharks flips the script. With entertaining competition, engaging underwater footage, and actual experts driving the narrative, the show combines education with action in a way that makes conservation both fun and credible. This is the kind of storytelling that builds trust and gets audiences inspired to protect the ocean.

Ocean careers are often imagined as adventurous and exciting, but what does it actually mean to work in the ocean every day, especially in the deep sea?

Ocean Ramsay's new documentary, called Shark Whisperer, is out on Netflix, and this is my review. This episode investigates Ocean Ramsey’s viral shark interactions, including her approach of touching and redirecting sharks in open water. We explore how these encounters influence shark behavior and why marine scientists warn about potential stress, habituation, and public safety concerns when sharks associate humans with food or physical contact.

Shark Conservation: We break down Ramsey’s role in raising awareness for shark conservation and her contributions to Hawaii’s 2021 shark fishing ban. While supporters credit her high-profile advocacy with inspiring public action, critics question whether her methods overshadow the Kanaka-led cultural and scientific leadership behind the legislation.

Shark Touching: We examine the controversy surrounding Ramsey’s touching of sharks, allegations of chumming or handfeeding, and inconsistencies around her educational credentials. We also highlight how her large online following can inspire positive ocean awareness but sometimes leads to online attacks against scientists working on shark conservation through rigorous research.

Ocean Conservation Disconnect defines the state of ocean conservation today, where public enthusiasm rarely translates into real impact. The viral plastic straw campaign proved that a simple symbol could spark global conversations, yet it shifted focus away from the systemic changes needed to reduce ocean plastic. Swapping plastic for metal straws may feel empowering, but it does not challenge the corporations and industries fueling the crisis.

Ocean Ramsey represents a modern paradox: charismatic advocates who bring sharks to mainstream attention, but sometimes offer shallow solutions. As her upcoming Netflix documentary looms, we must question how much these stories drive meaningful conservation or simply entertain. Coupled with the lack of access to primary science locked behind paywalls, the public is left inspired but uninformed, unable to engage beyond surface-level actions. This episode explores why these barriers persist and how we can bridge the gap between ocean science and society.

Tuna sustainability is more than a buzzword—it’s a complex challenge tackled head-on by the International Seafood Sustainability Foundation (ISSF). In this episode, Susan Jackson, ISSF President, joins host Andrew Lewin to unpack their groundbreaking 2024 Annual Report. From developing biodegradable jelly-FADs to advancing electronic monitoring standards, Susan explains how ISSF works with fishers, corporations, and NGOs to make global tuna fishing more sustainable and transparent.

Electronic monitoring takes center stage as Susan discusses how vessel-level cameras and sensors are reshaping compliance in tuna fisheries. She also highlights the Proactive Vessel Register (PVR), which now includes over 1,700 vessels committed to ISSF conservation measures.

French Polynesia marine protected area is now the largest in the world, covering nearly 4.8 million square kilometers of ocean. This groundbreaking conservation effort was announced during the United Nations Ocean Conference and includes large no-take zones near the Society and Gambier Islands, along with expansive areas that restrict harmful activities like deep-sea mining and bottom trawling. The MPA recognizes traditional fishing rights while also preserving critical marine habitats.

Marine conservation leadership by French Polynesia demonstrates how small island states can make bold commitments to global biodiversity. Backed by IUCN standards and set to expand by another 500,000 km² by 2026, this initiative offers hope in a world where only 8.3% of the ocean is currently protected. In this episode, we explore what this means for ocean life, local communities, and global marine policy—and why the real work begins now with enforcement and support.

The problem with seaweed aquaculture is that it’s not always as ocean-friendly as it seems. While seaweed farming is often praised as a climate solution—able to sequester carbon, improve water quality, and support sustainable food systems—scientists are now warning that its rapid, unregulated expansion could be damaging vital marine ecosystems. In this episode of How to Protect the Ocean, we dive into how seaweed farms are being placed over seagrass meadows, disrupting fish nurseries, smothering biodiversity, and altering water chemistry in ways we’re only beginning to understand.

You’ll hear about the overlooked risks, from nutrient depletion and fertilizer runoff to coral reef shading and invasive species. We also explore solutions: better regulations, smarter zoning, and the importance of protecting seagrass habitats that store carbon and support marine life. Seaweed aquaculture can be part of the solution, but only if we act with caution and science in mind.

UNOC 2025 brought major headlines in ocean conservation—from billions pledged to protect biodiversity, to significant movement on the High Seas Treaty. In this episode, Andrew Lewin returns from the UN Ocean Conference in Nice, France, with a firsthand account of what was announced, what was promised, and what might actually happen.

Ocean finance was a hot topic this year. Governments, development banks, and private investors pledged record-breaking funding to tackle everything from plastic pollution to marine ecosystem restoration. But Andrew dives into why these billions still fall short—and which key ocean players stepped up (and who didn’t).

High Seas Treaty ratification took center stage, with 18 new countries signing on and momentum building fast. The episode also breaks down 30x30 targets, new marine protected areas—including a massive one in French Polynesia—and growing global support for a deep-sea mining moratorium. Andrew adds his personal observations and concerns about whether this enthusiasm will translate into real protection for the ocean.

Why Cayman Islanders Voted against a massive cruise ship pier is a rare and powerful story of reef protection over profit. In this episode of How to Protect the Ocean, Andrew Lewin unpacks the bold decision by Cayman citizens to reject a development project that would have severely damaged their coral reef ecosystem. The vote sent a clear message: the long-term health of the ocean matters more than short-term tourism dollars.

Why Cayman Islanders Voted is also a reminder that grassroots action can be effective. Andrew explores how this vote happened, what it means for ocean conservation around the world, and how you can channel this momentum into protecting your local waters. He also introduces The Undertow, a growing community of ocean advocates working to inspire and support action like this on a global scale.

Climate policy in the U.S. has taken a wild ride in recent years. In this episode of How to Protect the Ocean, I speak with Chris Moyer, founder of Echo Communication Advisors, about the turbulent shifts in federal policy—especially during the Trump and Biden administrations, and how these shifts have disrupted progress in renewable energy. We examine the implications of these changes for energy development, environmental protection, and the impact of public messaging on political will to act.

Renewable energy isn’t just a technological challenge—it’s also a communication challenge. Chris breaks down how effective storytelling and smart policy design can turn the tide, even in politically divided landscapes. We also look at what the future might hold for climate action in the U.S. and what it all means for protecting the ocean and accelerating a transition away from fossil fuels.

Ocean recovery is not just possible, it’s already happening in places where we’ve taken action. In this episode, I dive into Ocean with David Attenborough, a documentary that reminds us of the ocean’s incredible resilience. From thriving coral reefs to fish populations bouncing back, the film offers powerful proof that when we give marine ecosystems space and protection, they can heal faster than we think. It’s a rare example of ocean storytelling that balances urgency with genuine optimism.

Bottom trawling, however, threatens that progress. The documentary pulls back the curtain on this destructive fishing method, revealing how vast swaths of ocean floor are scraped clean, alongside the fish, sharks, and invertebrates that live there. The fishing industry’s backlash has been swift, but the film doesn’t dwell on blame. Instead, it shows us that even in damaged habitats, life can return when given the chance. The hope is real—but only if we act now.

Tide gauges are a critical yet often overlooked tool in our fight to understand and respond to climate change. In this episode, Dr. Andrew Thaler returns to the podcast to share a powerful story about installing a tide gauge in his hometown of St. Michaels, Maryland. He breaks down how this simple device provides crucial data for flood risk, sea level rise, and community resilience, bringing science closer to home.

Community science is at the heart of Dr. Thaler’s work. We explore how grassroots efforts, low-cost technology, and open-source tools empower residents to monitor and respond to environmental changes themselves. Whether you’re a policymaker, scientist, or citizen concerned about the impacts of coastal flooding, this episode will deepen your understanding of how data can drive change from the bottom up.

Harmful algal blooms are wreaking havoc along the California coast, releasing toxic domoic acid that is poisoning marine life. In this episode, we explore how this naturally occurring toxin is causing mass die-offs in sea lions, dolphins, and seabirds, and why climate change and nutrient pollution may be making these blooms worse. You’ll hear about the science behind domoic acid, its neurological effects on animals, and how it mimics epilepsy symptoms in marine mammals.

Domoic acid poisoning is becoming a more frequent and devastating threat to ocean ecosystems, pushing wildlife rescue centers to their limits. We discuss the broader implications of this crisis on marine conservation efforts and public health, and what we can do to protect vulnerable species as ocean temperatures rise. This is not just a marine science issue—it’s an urgent conservation challenge that demands our attention.

Ocean conservation isn’t always about what’s happening in the water—it’s also about the choices we make on land. In this episode, we speak with Maddie Hamann, a former oceanographer turned sustainable food entrepreneur. Maddie shares how her background in ocean science led her to co-found PACHA, a company that creates sourdough buckwheat bread using organic, regenerative practices. From nutrient cycles to sustainable packaging, Maddie explains how oceanography continues to inform her mission—even in the kitchen.

Sustainable food systems play a major role in protecting marine environments. Maddie breaks down why she and her partner chose buckwheat, how they built an ocean-friendly food brand, and how consumers can support businesses that align with ocean values. This conversation goes beyond the surface, connecting science, health, and sustainability in a delicious way.

Plastic pollution in the Maldives has become a serious environmental crisis, despite the nation’s image as a pristine paradise. In this episode of How to Protect the Ocean, host Andrew Lewin shares the inspiring story of Zazou Saeed—a young Maldivian surfer and ocean advocate—who rose to become a local conservation hero by campaigning against single-use plastics. From leading beach cleanups to working with NGOs like Save the Beach and Parley for the Oceans, Zazou sparked a grassroots movement that helped influence national policy.

Ocean conservation through local action is a powerful force. Zazou used art, storytelling, and education to mobilize Maldivian youth and drive home the consequences of plastic pollution on coral reefs, sea turtles, and marine life. Her efforts were instrumental in shifting public awareness and building momentum toward the Maldives’ plastic bans. This episode highlights how one passionate person can make a massive difference for their community—and the ocean.

Orca conservation takes center stage as we highlight an inspiring community-led effort to protect these iconic marine mammals. Andrew explores how nearshore ocean heroes are driving real change, and why their stories matter more than ever. Learn how protecting your local waters can lead to healthier oceans worldwide—and why it’s time we recognize those leading the charge.

Shark encounters on social media spark a deeper discussion on wildlife ethics, as Andrew reacts to a TikTok video that demonstrates exactly what not to do. Wrapping up the episode is a look at David Attenborough’s new film “Ocean”, including an eye-opening sequence on bottom trawling and what it reveals about modern ocean challenges. Whether you’re an ocean lover or new to marine conservation, this episode offers compelling stories that educate and inspire.

Nearshore conservation is often overlooked in favor of flashy offshore marine protected areas. But a growing movement of community-led initiatives is showing that protecting coastal waters might be one of the smartest, most effective ways to safeguard ocean biodiversity and build climate resilience. This episode explores new insights from the Nearshore Ocean Progress report by the Center for American Progress, which highlights successful local conservation efforts across the U.S.

Community-driven ocean protection has the power to achieve more than top-down mandates. By focusing on the waters closest to home—estuaries, reefs, salt marshes, and seagrasses—coastal residents are preserving biodiversity, supporting livelihoods, and defending their homes against sea-level rise and extreme weather. Learn why investing in these initiatives may be the most impactful ocean action you can take.

Energy policy shifts in the U.S. are sparking concern as the government rolls back environmental regulations to fast-track oil and gas drilling. In this episode, we examine how these rollbacks could jeopardize ecosystems, especially marine environments, and undermine efforts to transition to clean energy sources.

Environmental protections have long served as safeguards for biodiversity and climate resilience, but these new changes prioritize short-term energy gains over long-term sustainability. We discuss the potential consequences for marine protected areas, public health, and climate policy, and what you can do to take action.

Equity, Diversity, and Inclusion (EDI) have become integral components of Canadian science funding. In this episode, we explore Pierre Poilievre's plan to strip funding from research programs that incorporate so-called "woke" policies like EDI. We examine how EDI policies are currently embedded in major grants from NSERC, SSHRC, CIHR, and more, and discuss what could be at stake for Canada's research innovation if these changes move forward.

Pierre Poilievre's proposal has sparked a broader debate within the Canadian academic and scientific communities. Many fear that removing EDI requirements could turn back progress made toward ensuring more inclusive and impactful research environments. We'll dive into what these policies actually achieve, why they were implemented, and the potential future of science in Canada.
