Heritage in the UN Decade of Ocean Science for Sustainable Development (2021-2030) and Beyond (U Edinburgh Press, 2025) outlines the need to embed Ocean Heritage into ocean science, sustainable development, and marine conservation to meet the goals of the UN Decade of Ocean Science for Sustainable Development (2021–2030) and beyond. Ocean Heritage—spanning tangible sites, such as shipwrecks or submerged harbours, and intangible connections such as traditional practices and knowledge systems—remains underrepresented in ocean governance. Yet it offers critical insights for more effective policy and research. Its inclusion is essential to ensuring science is informed by human–ocean relationships and responsive to the needs of communities. Led by the Cultural Heritage Framework Programme (CHFP), the Ocean Decade's only programme focused on Ocean Heritage, this text demonstrates how heritage supports all 10 Ocean Decade Challenges. Ocean Heritage strengthens climate adaptation, improves spatial planning, and supports equitable governance by grounding decisions in historical context and lived experience. The paper draws on more than 20 CHFP-endorsed initiatives, offering clear case studies and actionable recommendations for policy alignment, institutional support, and multidisciplinary collaboration. As the Ocean Decade reaches its midpoint, this book offers a path forward: one where science draws on the full range of human—ocean relationships to guide sustainable, equitable action. Ocean Heritage is not a symbolic gesture—it is a fundamental human right. Rather than treating culture as an add-on to marine conservation, this paper calls for its broad integration into ocean science and decision-making. Athena Trakadas is a maritime archeologist who studies underwater and coastal marine cultural heritage and advises international and national heritage, marine science and governmental organizations. Helen Dewar is an historian of the Atlantic World and French colonization in North America in the 17th and 18th centuries. She is a professor of history at the Université de Montréal (Québec, Canada) and the author of Disputing New France: Companies, Sovereignty and Law in the French Atlantic, 1598-1663 (McGill-Queen's University Press, 2022). helen.dewar[at]umontreal.ca Helen's institutional website Learn more about your ad choices.

Save Ocean Sensors: The Fight Over the Ocean Observatories Initiative A $386 million network of nearly 900 ocean sensors stretching across five sites from Oregon to Alaska to Greenland was being quietly dismantled, with no warning to Congress and no explanation to the public. In this episode, we trace the fight to save the Ocean Observatories Initiative: what this network actually does, why it matters far more than most people realize, and how a Democrat from Oregon and a Republican from Alaska teamed up to pass a bill stopping it in the span of a day and a half. We talk with Craig McLean, who spent more than 40 years at NOAA, including two stints as NOAA's Chief Scientist, about what's really at stake when ocean monitoring infrastructure disappears, and why this fight is part of a much bigger pattern. We also revisit a warning from a past guest, marine ecologist Dr. Andrew Thaler, that's looking less hypothetical by the day, and lay out exactly what you can do to help make sure this win sticks. In This Episode What the Ocean Observatories Initiative actually measures, and why it matters for your weather forecast, your insurance rates, and what farmers plant each season The Coastal Endurance Array off Oregon and Washington, and why pulling it out right as an El Nino forms is especially bad timing, per OSU oceanographer Jack Barth How Senators Jeff Merkley (D-OR) and Lisa Murkowski (R-AK) found out sensors were already being removed, and how they got the Saving the OOI Act passed unanimously in under two days Craig McLean's read on why this kept happening, from the role of the Office of Management and Budget to the broader pattern of cuts to federal science A look back at a warning from marine ecologist Dr. Andrew Thaler about Project 2025's plans for NOAA, and how that warning is playing out in real time What happens next: the NSF's review process, and how you can track it and find out where your own senators stand Featured Voices Craig McLean spent over 40 years at NOAA, where he founded the Ocean Exploration Program and served as NOAA's Chief Scientist, including being reinstated after being removed from the role for defending scientific integrity. He is now a senior fellow at the Ocean Foundation. Senator Jeff Merkley (D-OR) and Senator Lisa Murkowski (R-AK) led the bipartisan push for the Saving the OOI Act, featured here via Senate floor remarks. Dr. Andrew Thaler, marine ecologist and conservation technologist, returns in spirit from a past episode where he broke down Project 2025's plans to dismantle NOAA. Jack Barth, oceanography professor at Oregon State University, provided background on the Coastal Endurance Array via KATU News. The Bill The Saving the OOI Act passed the Senate unanimously, pausing NSF's decommissioning of the Ocean Observatories Initiative pending a full review with stakeholder input. It was led by Senators Merkley and Murkowski and cosponsored by Senators Dan Sullivan (R-AK), Maria Cantwell (D-WA), Ron Wyden (D-OR), Jack Reed (D-RI), Tammy Baldwin (D-WI), Sheldon Whitehouse (D-RI), Patty Murray (D-WA), Elizabeth Warren (D-MA), Edward J.

A new study found that small-spotted catsharks exposed to electromagnetic fields from subsea power cables showed a twenty-five percent reduction in transit time during direct current field exposure -- a subtle but measurable behavioral shift in animals that rely on electromagnetic sensing for survival. In this episode, I break down what a two thousand twenty-five marine biology study tells us about how living organisms respond to artificial electromagnetic fields in their environment. We look at what the researchers found, why elasmobranchs make such a revealing test subject, and what this kind of science means for how we think about EMF and biology more broadly. In This Episode Why sharks are uniquely sensitive to electromagnetic fields -- and what that sensitivity reveals What researchers found when catsharks were exposed to field-relevant EMF levels from subsea power cables How Hidden Markov Models helped detect behavioral shifts that standard observation would miss Featured Study Read the full study: From subsea power cable to small-spotted catshark Scyliorhinus canicula: Behavioural effects of electromagnetic fields in tank experiments See all studies at shieldyourbody.com/research

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 also look at the unique challenges facing marine ecosystems during times of conflict and why protecting biodiversity cannot simply be put on hold. This episode is about resilience, science, and hope. It highlights the dedication of researchers who continue gathering critical information under extraordinary circumstances and shows why every piece of knowledge matters for protecting our ocean.

LeAnn is a phytoplankton molecular ecologist, or, according to her daughter, a phytoplankton nerd. LeAnn grew up in Machias, and thanks to her participation in the Keller BLOOM Program at Bigelow Laboratory for Ocean Sciences as a junior in high school, she found her love for plankton and studying the ocean for a living. After receiving her Ph.D. in Cell and Molecular Biology from the University of Rhode Island in 2012, LeAnn returned to Maine - first as a postdoctoral researcher at Bigelow  and in 2018, joining the faculty at Maine Maritime Academy. LeAnn was one of this year's 5 Minute Genius speakers at the 2026 Maine Science Festival. Some definitions of the terms used during our conversation: eukaryotic - organisms whose cells have a membrane-bound nucleus. prokaryotic cells - organisms that  do not have a membrane-bound nucleus phytoplankton - mostly microscopic, single-celled photosynthetic organisms that live suspended in water. They form the base of the food chain and like all plants, take up carbon dioxide, make carbohydrates using light energy, and release oxygen.

Ocean conservation is often treated like an impossible problem, but the truth is simpler: when strong laws are created, enforced, and guided by science, ocean protection works. In this episode of How to Protect the Ocean, Andrew Lewin looks at the unglamorous but powerful role of legislation in ocean conservation. From Canada's Oceans Act and marine protected areas to the U.S. Endangered Species Act, Marine Mammal Protection Act, and Magnuson-Stevens Act, this episode shows how laws can help recover species, rebuild fisheries, and protect habitats. But laws only work when governments follow the science. Andrew also discusses what happens when political decisions override scientific advice, including concerns around the reopening of commercial cod fishing in Canada. This episode is about why ocean protection is possible, why enforcement matters, and why voters need to pay attention to leaders who treat the ocean as more than just a resource.

Ocean science can tell us what is happening to marine ecosystems, fisheries, climate impacts, and protected areas, but that information does not always reach the people who need it most. In this episode of How to Protect the Ocean, Andrew Lewin looks at the communication gap between researchers, policymakers, media, industry, and the public. The problem is not always a lack of science. Often, it is that the science moves slowly, social media moves instantly, and decision-makers do not always receive clear, accessible information in time to act. This episode explores why scientific papers can be difficult for the public to access, how misinformation spreads faster than careful research, and why ocean conservation needs stronger science communication, storytelling, and public engagement to turn knowledge into action.

NOAA helps protect millions of people before hurricanes, floods, tornadoes, and tsunamis hit, but most people never realize how much they rely on it. In this episode, we break down the hidden systems behind weather forecasting, emergency alerts, and disaster preparedness, and why cuts to NOAA could have consequences far beyond the ocean. Natural Disasters are becoming more intense in many regions, which makes accurate forecasting more important than ever. Better models, satellites, buoys, and warning systems give families more time to evacuate, secure homes, and stay safe. If those systems weaken, mistakes become more costly. Ocean Science is not separate from your daily life. It helps power the forecasts that guide airports, ports, coastal communities, and emergency managers. This episode explains why protecting science infrastructure may be one of the most practical ways to protect people. Listen to the full episode.

Episode Description Making babies is expensive. For pretty much every species on the planet, reproduction is supposed to be the ultimate metabolic investment—a massive energy drain that can make organisms vulnerable to stress, predators, and environmental change. Except there's a small shark walking around the Great Barrier Reef that apparently didn't get the memo. In this episode of our Ocean Lovin' series, we explore groundbreaking research from James Cook University that's forcing scientists to completely rethink what they know about the costs of reproduction. Epaulette sharks—those amazing little "walking sharks" that can literally stroll across reef flats on their fins—can produce complex egg cases with developing embryos inside without any measurable increase in energy use. Zero. Zilch. Nada. It's like building a house without buying any extra lumber. Join hosts Andrew Kornblatt and Dr. Frances Farabaugh, along with returning guest co-host Dr. Skylar Bayer, as we dive into this surprising discovery with Professor Jodie Rummer from James Cook University. We'll explore how her team measured something no one had measured before—the metabolic cost of egg-laying in sharks—and what they found challenges fundamental assumptions about reproduction in the ocean. We'll learn about the "pay as you go" hypothesis, discover why a tiny organ might be working overtime without changing the whole shark's energy budget, and explore what this means for sharks facing climate change. From the controlled environment of the lab to wild populations scattered across the Great Barrier Reef, this research reveals that evolution has equipped some species with surprising tools for survival that we're only beginning to understand.

In this Valentine's Day-themed episode, From Here Forward goes beyond conventional ideas of romance to explore love, cooperation, and connection in the marine world. Hosts Carol Eugene Park and Jeevan Sangha are joined by UBC professor Dr. Andrew Trites, Director of the Marine Mammal Research Unit, to discuss groundbreaking research revealing a surprisingly collaborative relationship between orcas and dolphins. From dolphin “scouts” and killer whale teamwork to physical touch as a love language, this episode reimagines companionship through the eyes—and sonar—of our marine mammal cousins. 

90% of seafood consumed on the Oregon coast is imported, while most Oregon-caught seafood gets exported. This week, we explore how that's changing. We talk with Suzie O'Neill, Kaitlyn Rich, and Jon Bonkoski from Ecotrust, who just launched "Tending the Tides," a podcast about mariculture on the Oregon coast. Learn how oyster farmers became climate sentinels in 2007 when ocean acidification killed their larvae. Discover urchin divers using rock climbing techniques underwater in 50 pounds of lead, and how their catch feeds innovative closed-loop aquaculture systems growing seaweed and sea cucumbers. From selective breeding programs creating climate-resilient oysters to kelp forests buffering acidification, this episode reveals how Oregon is building regenerative ocean farming that honors Indigenous stewardship, avoids parachute science, and redefines what sustainable food systems look like. Featuring the Oregon Coastal Mariculture Collaborative's community-led approach to expanding "unfed aquaculture"—oysters and seaweed that grow without any inputs beyond what the ocean provides.

What happens when an entire industry rushes forward before science can catch up? In this episode of Ocean Science Radio, we sit down with Dr. Andrew Thaler, deep-sea ecologist and CEO of Blackbeard Biologic, to explore his groundbreaking report for the Convention on Migratory Species that reveals exactly how much we don't know about deep-sea mining's impacts on whales, dolphins, sharks, turtles, and other highly migratory species. While most deep-sea mining research has focused on the immediate destruction of seafloor ecosystems, Andrew's report exposes a more troubling reality: we have massive knowledge gaps about how mining operations—with their noise, sediment plumes, and habitat disruption—might affect species that travel thousands of miles across interconnected ocean basins. From sea turtles navigating by magnetic fields to whales relying on acoustic communication, these far-reaching impacts remain largely unstudied even as the industry accelerates toward commercial production. The conversation takes a timely turn as we discuss the Bureau of Ocean Energy Management's controversial Request for Information for mining in U.S. waters off the Commonwealth of the Northern Mariana Islands. Andrew breaks down why this represents a significant shift from international deep-sea mining debates, and what it means that communities near the Mariana Trench—with only a 30-day comment period and no guaranteed revenue sharing—are being asked to accept an industry that science hasn't fully evaluated. As the Trump administration pushes to fast-track deep-sea mining for critical minerals while international bodies like the CMS urge precaution, this episode asks the essential question: what's at stake when we mine what we haven't studied? Join us for a conversation that bridges cutting-edge marine science, environmental justice, and the real-world policy decisions happening right now in the deep ocean.

The source introduces Vanguard, a newly designed and built subsea human habitat, which will enable a new era of marine biology research by allowing aquanauts to live and work underwater at ocean pressure for extended periods. This saturation diving capability eliminates the significant time loss associated with traditional daily dives, allowing researchers to conduct up to nine hours of actual underwater work per day for missions lasting weeks or months. Experts emphasize that living at depth will revolutionize science by enabling long-duration observations of complex marine processes, such as coral growth and the diel vertical migration. Furthermore, Vanguard will facilitate critical research into the effects of hyperbaric environments on the human body, providing insights for both undersea activities and space analog missions.Original article = https://www.newscientist.com/article/2507031-how-aquanauts-will-change-our-view-of-the-ocean/#VanguardHabitat #SubseaHabitat #Aquanauts #SaturationDiving #UnderwaterHabitat #OceanScience#MarineBiology #DeepSeaResearch #LivingUnderwaterhttp://atlantisseacolony.com/https://www.patreon.com/atlantisseacolonyhttps://discord.gg/jp5aSSkfNS

Sperm whales are among the most extraordinary creatures on the planet—massive, deep-diving, highly social, and constantly communicating. David Gruber, marine biologist and founder of Project CETI, leads a global team of scientists using cutting-edge technology to decode the vocalizations of these remarkable animals. A 2025 Tällberg-SNF-Eliasson Global Leadership Prize winner, Gruber explains how understanding whale communication isn't about speaking to them, but about learning how they see and interact with the world we share. In this episode, he discusses the science, wonder, and purpose behind CETI—and what unlocking whale language could mean for humanity.

After nearly two decades of negotiations, the world has finally agreed on a framework to protect the high seas - that vast expanse of ocean beyond any nation's control that covers nearly half our planet's surface. On January 17th, 2026, the BBNJ Agreement (Biodiversity Beyond National Jurisdiction), commonly known as the High Seas Treaty, officially enters into force, becoming international law.Join us as we explore this historic moment with two experts at the heart of the effort. Jeremy Raguain, who works with the Alliance of Small Island States, shares insights on Africa's leadership in the negotiations and what meaningful capacity building looks like for developing nations. Rebecca Hubbard, Director of the High Seas Alliance, takes us through the coalition-building journey from 2002 to today, explaining the treaty's four pillars: marine protected areas, equitable benefit-sharing from marine genetic resources, environmental impact assessments, and capacity building.This isn't just another international agreement - it's the missing piece that could finally allow us to protect 30% of the ocean by 2030, ensure that benefits from ocean resources flow equitably to all nations, and shift away from "parachute science" toward true partnerships. From small island nations reclaiming their identity as "big ocean states" to the complex work of enforcing protections in the world's most remote waters, this episode explores what becomes possible when the world comes together to protect what belongs to us all.Whether you live on a coast or in a landlocked country, half the oxygen you breathe comes from the ocean. Its health is humanity's health. Discover why this treaty matters for everyone, and what you can do to support its implementation.Featured Guests:Jeremy Raguain, AOSIS Fellowship Director & Ocean Governance SpecialistRebecca Hubbard, Director of the High Seas AllianceEpisode Length: 35-40 minutes

Most of us know the story of the Titanic. In 1912, the massive — supposedly indestructible — steamship sank after hitting an iceberg on its first and only journey across the Atlantic Ocean. Titanic remained undiscovered on the seafloor, somewhere in the North Atlantic Ocean, for 73 years, until it was found nearly two miles beneath the surface. But now the ship might be disappearing again, this time for good. And the culprit is not another iceberg — it's something much, much smaller.

Thirty years after the United Nations first called for global action on climate change, progress remains painfully slow. Year after year, world leaders meet, make promises, and defer real solutions. Why? Because top-down global governance continues to fail in a world divided by power, politics, and inequality. In this episode, Linwood Pendleton, Global Coordinator of the Ocean Knowledge Action Network, argues that it's time to look elsewhere for answers. Drawing on his work with Indigenous academics, ocean scientists, and local communities around the world, he explains why true progress depends on wisdom from the ground up. Hope, he insists, lies not in endless summits—but in reconnecting with knowledge systems that already know how to live in balance with the planet.

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.

What happens after you flush? Most of us don't think about it—but maybe we should. In this eye-opening episode, we dive into one of the ocean's biggest but least discussed threats: wastewater pollution.Join us as we talk with Jos Hill, Program Director for The Nature Conservancy's Wastewater Pollution Program and creator of the groundbreaking podcast "waste(d)water." Jos reveals the shocking scale of this crisis: 80% of wastewater worldwide is inadequately treated, 58% of coral reefs are exposed to wastewater pollution, and wastewater accounts for a staggering 40% of coastal nutrient pollution—nearly as much as agriculture.Discover how even highly treated wastewater can devastate marine ecosystems, why coral disease outbreaks in the Florida Keys have been traced back to human gut pathogens, and how nutrient-rich wastewater is making coral reefs more vulnerable to marine heat waves and climate change.But this isn't just doom and gloom—Jos shares inspiring recovery stories from Kaneohe Bay in Hawaii and Tampa Bay in Florida, proving that when pollution is addressed, ecosystems can bounce back. Learn about innovative nature-based solutions, including treatment gardens that clean water while growing food for coastal communities.From the intersection of wastewater pollution and social justice to practical steps you can take in your own community, this conversation breaks the taboo around a topic that affects every person on the planet. As Jos reminds us: everyone goes to the toilet, so this issue is relevant to everyone.It's time to start talking about the dirty secret of ocean pollution—because we can't solve problems we won't discuss.Featured Guest: Jos Hill, Program Director, Wastewater Pollution Program, The Nature ConservancyLearn more: Check out the waste(d)water podcast and follow @wastedwaterpod wherever you listen to podcasts.

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.

Host Dave Schlom is joined by guests from the Scripps Institution of Oceanography at the University of San Diego to profile the ocean science being done at one of the world's most important and historic places to study our blue planet.

The land we now call Scripps Oceanography has been home to the Kumeyaay people for thousands of years. A history of encroachment, colonization and displacement from coastal lands has challenged Kumeyaay ocean traditions and practices. Today, Kumeyaay-Iipay-Tipay people are actively revitalizing Indigenous ocean culture. As part of Perspectives on Ocean Science Lecture Series, Stan Rodriguez and Priscilla Ortiz Sawah of the Iipay Nation of Santa Ysabel, and Andrew James Pittman of the Los Coyotes Band and Cupeño Indians, talk about the history of the Kumeyaay culture in the region. Through community efforts, they are rebuilding traditional ha kwaiyo (tule boats), harvesting ha shupill (grunion) and teaching language about the ocean (ha silowik). These intergenerational practices embody Indigenous resilience, resistance and revival — nurturing and evolving Indigenous ocean knowledge, culture and traditions. Series: "Jeffrey B.

Forget everything you think you know about viruses. In the ocean, there are viral giants so large they were mistaken for bacteria for decades – and they're rewriting the rules of marine ecology.Join us as we explore the fascinating world of giant viruses with Benjamin Minch, a PhD student at the University of Miami who has discovered over 230 previously unknown viral genomes using a revolutionary computational tool called BEREN. These microscopic monsters can hijack photosynthesis, manipulate their hosts like puppet masters, and dramatically reshape ocean food webs.Giant viruses are up to 100 times larger than common viruses, with genomes rivaling those of bacteria. Some enhance their hosts' superpowers – boosting photosynthesis and metabolism – before turning infected cells into viral factories. Others cause victims to clump together and sink as marine snow, playing crucial roles in carbon sequestration and climate regulation.From the Baltic Sea's viral treasure trove to practical applications like predicting harmful algal blooms, this episode explores how invisible giants influence everything from ocean food webs to global nutrient cycles. Discover why the ocean's biggest players might also be its smallest.Links:BEREN tool: https://www.biorxiv.org/content/10.1101/2024.10.09.617401v1Ben's research publications: https://idsc.miami.edu/pegasus-powered-giant-virus-study-yields-publicly-shared-bioinformatics-tool/

Shark communication is critical in changing their "man-eating" reputation from the movie Jaws. Sharks need protection so telling people about the wonders of sharks is essential. Marine biology is more than just a job — it's a lifestyle driven by passion and purpose. In this episode of How to Protect the Ocean, host Andrew Lewin speaks with marine biologist Kenzie Horton, who shares how her love for the ocean shaped her career. Based in Florida, Kenzie juggles a full-time role in state government, a master's degree researching white sharks, and a growing platform on TikTok where she busts marine science myths and offers ocean safety tips. Ocean science communication is at the heart of Kenzie's mission. She uses humor, storytelling, and relatable advice to connect with a broad audience online — from what swimsuits not to wear in the ocean to real shark science. If you're curious about how to blend marine conservation with viral content or want to know how to break into the field of marine biology, this episode is a must-listen.  

Plastic pollution is one of the most pressing threats to our oceans today. In this episode, we explore how microplastics—tiny fragments of plastic waste—make their way into tropical marine ecosystems and cause lasting damage. Whether it's through broken-down consumer products or fishing gear, plastic pollution infiltrates ocean habitats and harms marine life in ways we're just beginning to understand. Coral reefs, often called the rainforests of the sea, are especially vulnerable to plastic pollution. These vital ecosystems support biodiversity, protect coastlines, and sustain livelihoods. Dr. Lisa Rodrigues, a professor at Villanova University, shares her research on how microplastics impact coral health, disrupt growth, and even contribute to disease in reef systems. Plastics can also alter water quality and affect the delicate balance that coral reefs depend on to thrive. Marine debris isn't just unsightly—it's a serious ecological problem. From lionfish to tiny plankton, organisms across the food chain are ingesting plastics or suffering from habitat degradation. Dr. Rodrigues explains how even pristine-looking beaches can hide layers of microplastics beneath the surface. We also discuss how citizen science, beach cleanups, and community involvement play key roles in fighting plastic waste in coastal areas. Ocean conservation efforts must include tackling plastic pollution at its source. In this episode, we talk about the role of environmental policy, education, and innovation in reducing marine plastic waste. Whether you're an activist, student, diver, or beach lover, there are actionable ways you can help protect coral reefs and reduce the plastic footprint in our oceans.   Follow a career in conservation: https://www.conservation-careers.com/online-training/ Use the code SUFB to get 33% off courses and the careers program.   Do you want to join my Ocean Community?
