Nearly 2,000 Volunteers Just Answered the Ocean's Biggest Question
How To Protect The Ocean
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...

The Silent Damage Behind Your Canned Tuna
How To Protect The Ocean
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 drifting FAD washes onto...

The Hidden Solar Power Plant Living on Coral Reefs
How To Protect The Ocean
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...

What Happens to Your Water Before the Coast Floods?
How To Protect The Ocean
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...

The World Just Promised Billions, But Will the Ocean Benefit?
How To Protect The Ocean
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...

What Dead Seabirds Are Trying to Tell Us About the Pacific Ocean
How To Protect The Ocean
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...

Who Really Decides Canada’s Climate Future?
How To Protect The Ocean
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...

The Hidden Ocean World Most of Us Will Never See
How To Protect The Ocean
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 of...

What We Don’t Know About the Ocean Could Cost Us Everything
How To Protect The Ocean
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...

How Do Scientists Explore a Place Humans Can’t Survive?
How To Protect The Ocean
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...
info_outlineThe High Seas Treaty took nearly 20 years to negotiate, not because countries disagreed that the ocean matters, but because ocean protection becomes much harder when money, power, access, and fairness are involved.
In this episode of How to Protect the Ocean, we look at why protecting the high seas is so politically difficult. From industrial fishing fleets and marine genetic resources to enforcement, ratification, and accountability, this story shows why global ocean conservation is never just about science.
The treaty creates a framework for protecting biodiversity beyond national borders, but the real test is what happens next. Will countries turn the agreement into real action, or will it become another symbolic promise?
