How To Protect The Ocean

YouTube has quietly become one of the best platforms for ocean science communication, and in this episode Andrew breaks down exactly why. Fresh off yesterday's 2,000-episode milestone and the new Pisces Oceans licensing agreement, Andrew explains why he's diving back into YouTube after stepping away last spring, including the launch of a brand new daily show, Ocean Decoded Live.

Andrew walks through his own history with video, from the early days of Speak Up for Blue TV through burnout, a rebrand, and now a fresh start under Ocean Decoded. He breaks down why YouTube's search-driven discovery beats...

Today marks episode 2000 of How to Protect the Ocean, and Andrew is taking a break from the usual format to look back at how this show came to be. From an accidental start in 2010 to a name change driven by search engine optimization, to over 3 million downloads across 11 years, this episode traces the full arc of the podcast's history.

Andrew also opens up about how podcasting reshaped his career. What started as a side project outside of work hours led to TV documentary appearances, podcast hosting offers including a multi-year run on the Toronto Zoo podcast, and...

Podcasting has been part of Andrew Lewin's life for 11 years, and in this episode he explains why he thinks more people working in ocean science and conservation should be doing it too. He walks through what makes long-form audio and video different from the short clips discussed in yesterday's episode: the ability to sit with complex topics, tell a full story, and reach an audience that's multitasking, whether they're walking the dog, working out, or gardening while listening.

Andrew gets specific about what podcasting actually requires. He covers how titles and the first several seconds of an...

This week on the How to Protect the Ocean podcast, Andrew kicks off a science communication series exploring how ocean advocates can spread awareness across every major content format. Today's episode digs into short-form video: TikTok, Instagram Reels, and YouTube Shorts, and what it actually takes to make original content work when you're used to talking for an hour, not ninety seconds. Andrew is candid about his own struggle with the format, since most of his short-form output today is repurposed podcast clips rather than content built for the platform from the ground up.

The conversation covers...

Electric boating is having its Tesla moment, and few people understand that shift better than Alexandre Mongeon, CEO and co-founder of Vision Marine Technologies. Andrew sits down with Alexandre to trace his path from importing speed boats in Montreal to building the electric outboard systems now powering boats across North America. Along the way, Alexandre shares how a chance meeting with Olympic sailor and boat designer Ian Bruce set him on the road to electric propulsion, and how a rental-to-sale showroom model in Newport Beach, California, turned a small hobby business into a NASDAQ-listed company.

The conversation...

Not every ocean conservation win comes from a nonprofit or a government program. In this episode, Andrew breaks down three for-profit companies that are cleaning up the ocean, funding wildlife research, and paying living wages to the people doing the work. These businesses show that conservation and profit are not opposing goals. They can be the same goal.

Andrew covers 4Ocean, whose full-time captains and cleanup crews earn living wages with health insurance and bonuses across Florida, Bali, Haiti, and Guatemala. He covers Ocean Sole, the Kenyan social enterprise that pays local collectors for discarded flip-flops and...

4ocean has removed more than 50 million pounds of plastic and trash from the world's oceans, rivers, and coastlines. That milestone did not come from a government program or a traditional nonprofit. It came from a for-profit business built around a single idea: every bracelet sold funds the removal of a pound of ocean trash.

In this episode, Andrew breaks down how 4ocean went from one viral video in Bali to a global cleanup operation, why founders Alex Schulze and Andrew Cooper chose a business model over a nonprofit, and how the company built local jobs, recycling infrastructure...

The boat rental market is bigger than most people realize, and it's growing fast. In this episode, Andrew shares a personal story about his dad, boats, and why he's spent the last few months considering buying one, before walking through the data that changed his mind about ownership altogether.

Andrew breaks down the numbers behind the boat sharing economy: a market valued between nineteen and twenty three billion dollars US, growing five to seven percent a year, with electric propulsion emerging as the fastest growing segment in boat rentals. Peer to peer platforms like Getmyboat, Boatsetter, Click...

Global shipping moves roughly 80 to 90% of the world's trade, and it comes with a real climate cost: the industry is responsible for a little over 2% of global CO2 emissions. On today's episode of the How to Protect the Ocean Podcast, Andrew looks at one of the more surprising fixes the industry is turning to: sails. Not the old canvas kind, but massive rigid wing sails retrofitted onto modern cargo vessels to cut fuel use and emissions without waiting on next-generation fuels.

The centerpiece example is the Pyxis Ocean, a bulk carrier fitted with two 37.5-meter WindWings that...

Hollywood might not be the first industry you think of when it comes to protecting the planet, but film and TV production has been quietly transforming how it operates behind the scenes. In this episode, Andrew sits down with Zena Harris, founder and president of Green Spark Group and co-host of The Tie-In podcast, to unpack what sustainability actually looks like on a working film set.

Zena walks through the surprising ways major productions are cutting fuel consumption, swapping diesel generators for solar power and battery stations, and building a circular economy for set materials instead of...

Businesses love to say they are sustainable. Andrew breaks down why that word is no longer enough on its own. A new EU consumer protection regulation now requires companies to prove environmental claims with evidence, and it has helped drive more than 400 greenwashing-related enforcement actions across the US, UK, EU, Canada, Australia, and India in 2026 alone.

Andrew draws on his own university experience with food labeling regulation to explain how vague standards let companies technically comply while misleading the public, then walks through real cases including SEC fines against Goldman Sachs, DWS, and WisdomTree Asset Management, state...

Sustainability conversations usually center on ecosystems, emissions targets, and corporate pledges, but this episode makes the case that people belong at the center of that conversation too. Andrew looks at how communities living closest to refineries, extraction sites, and industrial waterfronts carry a disproportionate share of the pollution burden, often without having consented to the risk in the first place.

Using a Philadelphia refinery as a case study, Andrew walks through how fenceline communities experience higher poverty rates, higher rates of residents of color, and elevated cancer and respiratory risk compared to their surrounding cities. He extends...

Sustainability isn't just good PR; it's good business math. In this episode, Andrew breaks down why companies are shifting toward circular business models, using Philips Lighting as a case study in selling light as a service instead of a product. He digs into the economics behind the shift: a British industrial symbiosis study that saved companies significant money and cut CO2 emissions, a PwC Sweden study showing double-digit operating cost reductions in circular electronics, and the rise of sustainability-linked loans that reward companies for hitting circularity targets with lower interest rates.

Andrew also gets honest about the...

Sustainability anxiety is real. Watching wildfires spread, sea levels rise, and ice melt while governments drag their feet on climate policy can leave anyone feeling stuck. Andrew opens today's episode by naming that frustration directly, then makes the case for where real momentum is actually coming from: business.

This episode breaks down why companies are adopting sustainability practices, sometimes because they want to and sometimes because regulation and consumer pressure leave them little choice. Andrew walks through the European Union's corporate sustainability due diligence directive, a law requiring large companies to address environmental and human rights harms...

Conferences can feel intimidating, expensive, and overwhelming, especially if networking doesn't come naturally to you. In this episode, Andrew shares what more than a decade of attending marine science and conservation conferences has taught him about making real connections, from picking the right event for your career stage to crafting an elevator pitch that actually works.

Andrew walks through how to choose a conference that fits your specific field, why in-person events build stronger professional relationships than virtual ones, and why even seasoned scientists like Dr. David Ebert still get approached by people battling imposter syndrome. He...

Marineland Canada is officially closing, and this week the park began moving its remaining beluga whales out of Niagara Falls. Six belugas were flown out on a single flight this week, four to the Shedd Aquarium in Chicago and two to SeaWorld San Antonio, marking the start of a rescue effort that has been years in the making. Andrew walks through how the park got here, from its 1961 founding through decades of protests, whistleblower allegations, OSPCA charges, and a failed 2025 attempt to export the belugas to a Chinese aquarium.

The episode traces the full timeline: the 2012 Toronto...

The US government is moving toward the world's first commercial deep-sea mining lease sale, and it's happening in federal waters off American Samoa. In this episode, Andrew breaks down how we got here: a California startup's 2025 request to mine polymetallic nodules, the Request for Information process that followed, and the 75,000-plus public comments that came in during the 30-day comment window, with 80 to 98% opposed to mining. Despite that opposition, and despite a standing moratorium from American Samoa's own governor, the federal government expanded the proposed mining area from 18 million to 33 million acres and pushed the lease sale forward, currently...

A viral TikTok about fish aggregation devices drifting into marine protected areas got Andrew thinking about a topic he hasn't covered in a while: ghost nets. In this episode, he breaks down what ghost nets actually are, the scientific term for them (ALDFG, or abandoned, lost, or otherwise discarded fishing gear), and why they're a growing, well-documented problem from the ocean surface all the way down to the deep seafloor.

Andrew walks through what the peer-reviewed research shows: entanglement patterns across whales, seals, sea turtles, and coral reefs, a personal diving story off Big Cayman where he...

For a week straight, Andrew watched his own sky turn orange outside Toronto as smoke from nearly 900 wildfires burning across Canada, most of them following the boreal forest from the east coast to Northwestern Ontario, drifted south into the US and back again. He walks through what actually happened on the ground: which towns and First Nations were evacuated, how bad the air quality got (Toronto briefly had the worst AQI in the world), and why northwestern Ontario, not a hugely populated area but home to vulnerable First Nations communities, bore the brunt of it.

Then he...

If you've ever felt a hard strike, fought a fish, and reeled up nothing but a head, you already know what shark depredation feels like. In this episode, Andrew breaks down a new study that tracked shark depredation across the entire Atlantic coast, from Maine to Texas and the US Caribbean, going back a full century to figure out why it's happening more now than ever before.

The study found at least 51 targeted fish stocks affected and 22 shark species involved, with bull sharks and sandbar sharks showing up most often. But the real story isn't that sharks...

A thousand meters down off the coast of Brazil, a deep-sea robot caught something almost no one has ever filmed alive: a giant open ocean octopus calmly eating a jellyfish. That moment, captured by the Schmidt Ocean Institute's ROV SuBastian aboard the research vessel Falkor (too), was part of a wider expedition that turned up more than two dozen species new to science, from glowing worms to glass squid to strange colonial siphonophores.

The discovery points to something bigger than one expedition. The ocean's midwater, the vast zone between the sunlit surface and the seafloor, is by...

In 1978, an Exxon scientist asked a question in capital letters: were the oceans dissolving coral reefs? By 1982, Exxon's own scientists had the answer, in writing. So did Shell by 1986. This episode traces a newly published Oxford University study that dug through more than fourteen thousand pages of fossil fuel industry documents and found that the world's biggest oil and gas companies understood, decades before the public did, exactly how their product would wreck coral reefs.

We walk through what the industry knew and when, how a funded think tank report in 2012 was built to look like an...

For more than a decade, almost 2,000 volunteers have walked California's beaches with clipboards, counting every swimmer, surfer, angler, and boat they see. It sounds simple, maybe even a little strange. But that pile of data, more than a million tally marks collected between 2012 and 2020, just answered a question marine scientists have debated for years: do marine protected areas actually work in the real world, not just on paper?

In this episode, we walk through what researchers found when they finally pulled that decade of volunteer data together. We look at how the MPA Watch program trains everyday...

Right now, somewhere in the open ocean, a raft the size of a small table is drifting with no one steering it. It's called a fish aggregating device, or FAD, and the tuna industry drops thousands of them into the water every year to lure fish to the surface. A new study published in Science Advances tracked where these rafts actually end up, and the answer is unsettling: they've likely drifted through more than half of the world's marine protected areas by total area, with over 6,300 strandings recorded across 174 protected areas in 53 countries and territories.

When a...

Scientists have uncovered an incredible secret hiding in plain sight on coral reefs. Some tropical sea sponges are able to harvest sunlight through microscopic algae living inside their tissues, giving them a surprising source of energy. It is a discovery that challenges what we thought we knew about one of the ocean's oldest animals.

In this episode, we explore how these ancient filter feeders use a partnership with algae to survive and thrive in nutrient-poor tropical waters. You'll learn why this relationship is similar to the one that helps corals build reefs and why researchers believe sponges...

Sea level rise isn't always dramatic. Long before homes disappear beneath the waves, coastal communities can lose something even more essential: safe drinking water. In this episode, we explore how saltwater is quietly moving into freshwater supplies across coastal Bangladesh and why this hidden impact deserves far more attention.

Using a recent Mongabay commentary as a starting point, you'll learn how rising seas, changing rivers, and human activities are combining to reshape one of the world's largest river deltas. The consequences extend beyond drinking water to agriculture, public health, local economies, and the future of entire communities...

The world just pledged more than $6.4 billion for ocean conservation at the 2026 Our Ocean Conference, but history tells us that big announcements do not always lead to meaningful action. In this episode, we unpack what was actually announced, who made the commitments, and why the headline number is only part of the story. You'll learn why this year's conference in Kenya was especially significant and what makes these commitments different from legally binding agreements.

We also explore the question that rarely gets asked: how do we know whether these promises will ever become real conservation outcomes? From...

Thousands of seabirds are washing ashore along California's coast, starving, exhausted, and unable to find enough food. While the images are heartbreaking, scientists say the birds are only the visible symptom of a much larger problem unfolding beneath the surface. In this episode, we explore why seabirds are dying and what their struggle reveals about the health of the Pacific Ocean.

You'll learn how marine heat waves are disrupting one of the world's most productive ocean ecosystems by reducing nutrients, shrinking fish populations, and breaking apart the marine food web. We also look at why seabirds act...

Canada has admitted it is no longer on track to meet its 2030 climate targets, but the reasons go far beyond domestic politics. In this episode, we explore how changing economic priorities are reshaping Canada's approach to climate action. The surprising twist is that many of these changes begin outside Canada's borders.

New U.S. tariffs and shifting trade policies are putting pressure on Canada's economy, forcing leaders to rethink where to invest and what to prioritize. As economic policy changes, climate policy often changes with it. We follow that chain of events to understand why Canada's emissions...

Most of us will never visit the deep ocean, yet it covers the majority of our planet and supports life in ways we're only beginning to understand. In this episode, Andrew Lewin wraps up the Surfacing Secrets series with Ocean Networks Canada by exploring why the deep sea remains one of Earth's greatest frontiers. You'll discover how scientists are uncovering hidden ecosystems that could reshape our understanding of the ocean.

Andrew is joined by Monica Peltz of Ocean Networks Canada and Heidi Gartner from Fisheries and Oceans Canada to discuss what it takes to study places thousands...

How do you protect something you barely understand? In this episode, we explore why ocean exploration is much more than discovering strange creatures or mapping the seafloor. Every marine protected area, conservation plan, and fisheries decision begins with one essential ingredient: knowledge.

You'll discover how scientists collect the information that guides conservation, from mapping underwater canyons to identifying coral gardens and sponge reefs that most people will never see. We also look at what happens when important ecosystems are damaged before we even know they exist, and why exploration gives decision makers the evidence they need to...

The deep ocean is one of the most extreme places on Earth. Crushing pressure, freezing temperatures, and total darkness make it impossible for humans to explore for long, yet scientists continue to make incredible discoveries thousands of meters below the surface. So how do they do it?

In this episode, you'll discover the remarkable technology that makes deep sea exploration possible. From remotely operated vehicles and autonomous underwater robots to multibeam sonar, artificial intelligence, and environmental DNA, these tools are transforming how we study one of the least explored parts of our planet. You'll also learn why...

Most people picture the deep sea as a dark, empty place where almost nothing can survive. The truth is far more surprising. Thousands of meters below the surface lives an extraordinary world filled with ancient corals, giant sponges, glowing jellyfish, strange fish, and species that scientists are still discovering today.

In this episode, you'll learn how life has adapted to crushing pressure, freezing temperatures, and complete darkness. You'll also discover why deep-sea ecosystems are some of the most important habitats on Earth, supporting biodiversity, fisheries, and even helping us better understand how life itself can evolve under...

How can we know more about the Moon and Mars than the bottom of our own ocean? It sounds impossible, but it is true. In this episode, we begin a special series on deep ocean exploration by uncovering why so much of our planet remains a mystery and why that matters more than ever.

The deep ocean plays a critical role in regulating Earth's climate, supporting marine life, and helping sustain the ecosystems we depend on every day. Yet scientists have only explored a tiny fraction of it because of crushing pressure, complete darkness, and the enormous...

What happens to marine conservation when a humanitarian crisis unfolds? In this episode of How to Protect the Ocean, we explore the remarkable story of marine scientist Mohammed Abu Daya, whose work studying endangered giant devil rays has continued despite the immense challenges of living and working in Gaza. His story reminds us that conservation is ultimately about people as much as it is about wildlife.

You'll learn why giant devil rays are among the Mediterranean's most vulnerable species, why scientists still know so little about them, and how local research can shape global conservation efforts. We...

For years, mangrove forests were seen as one of the world's fastest disappearing coastal ecosystems. Cleared for development, shrimp farming, and agriculture, these unique forests seemed locked in a steady decline. But a new global study tells a much more hopeful story. Researchers have found that mangroves are recovering in many parts of the world, offering one of the most encouraging conservation success stories in recent years.

In this episode, I break down why mangroves are so important for the health of our oceans and the people who depend on them. You'll learn how these coastal forests...

A potential super El Niño is developing in the Pacific Ocean, and scientists are warning that it could have major consequences for marine ecosystems around the world. While El Niño is a natural climate pattern, stronger events can dramatically alter ocean conditions by warming surface waters and reducing the nutrients that support marine food webs. In this episode, we explore why researchers are watching this event so closely and what it could mean for the future of the ocean.

One of the biggest concerns is how a super El Niño could affect fisheries and mar...

After 11 years of hosting How to Protect the Ocean, I wanted to take a step back and reflect on what the journey has taught me. What started as a simple passion project became a platform for ocean storytelling, science communication, and career development. Along the way, I learned lessons about persistence, networking, and creating opportunities that I never could have predicted when I published the first episode.

One of the biggest takeaways is that building a career in marine science and conservation is rarely a straight line. Many people enter the field because they love the ocean...

What happens when one of the world's most important ocean monitoring systems is nearly shut down?

The Ocean Observatories Initiative (OOI) collects critical data on ocean temperatures, oxygen levels, currents, marine ecosystems, and climate change. Earlier this year, parts of the program faced significant cuts, raising concerns among scientists, policymakers, and ocean advocates.

In this episode, we explore why researchers fought so hard to save the OOI, how the National Academies challenged the justification for the cuts, and why long-term ocean observations are essential for understanding climate change, marine ecosystems, and the future o...

The ocean is facing some of the biggest challenges in its history. Rising temperatures, marine heatwaves, coral bleaching, habitat loss, and overfishing continue to put pressure on marine ecosystems around the world. If you only follow the headlines, it can feel like ocean conservation is losing the battle.

But hidden within a recent United Nations ocean report is a surprising reason for optimism. While ocean health continues to decline in many areas, the systems designed to protect the ocean are getting stronger. Countries are expanding marine protected areas, improving international cooperation, deploying satellite monitoring technology, and developing...
