What Orcas Are Changing in Antarctica Might Surprise You
13-04-2026 | 9 Min.
What if Antarctica isn't changing as slowly as we think? And what if one of the biggest drivers of that change… is an animal most people only see as a top predator? In this episode, we look at what orcas are really doing in Antarctica, and why it might surprise you. These aren't just whales passing through a frozen landscape. They are specialized hunters with learned behaviors, working in coordinated groups, and possibly reshaping the ecosystem in ways scientists are still trying to understand. As sea ice melts and new areas of the Southern Ocean open up, orcas may be gaining access to places they couldn't reach as easily before. That shift could increase pressure on seals and penguins that already depend on ice for survival. But this story isn't about villains and victims. It's about how fast ecosystems can change when climate, habitat, and predator behavior all collide. In this episode, you'll learn: Why Antarctic orcas are more diverse than most people realize
How coordinated hunting shows signs of culture, not just instinct
What shrinking sea ice means for predator and prey dynamics; and
Why scientists may still be behind in understanding what's really happening
Antarctica might feel distant. But what's happening there could reshape how the ocean works far beyond the ice. Follow How to Protect the Ocean for more ocean science stories that explain what's really going on beneath the surface.

10-04-2026 | 52 Min.
Tuna fisheries are often seen as one of the biggest challenges in ocean conservation. But that story is starting to change, and most people have not caught up to it yet. In this episode, you'll hear how tuna fisheries in many parts of the world are actually improving. Better science, stronger monitoring, and more coordinated international management are helping rebuild stocks and reduce pressure on key species. To understand what's really happening, I spoke with Susan Jackson, President of the International Seafood Sustainability Foundation. She shares how data-driven decisions, harvest rules, and industry collaboration are changing the way tuna is managed globally. But progress does not mean the job is finished. Some stocks are still under pressure, and continued effort is critical to keep things moving in the right direction. This episode breaks down what's working, where challenges remain, and why tuna fisheries may be one of the most important examples of how ocean conservation can succeed when science and policy align.

Why the Tuna on Your Plate Didn't Run Out
08-04-2026 | 11 Min.
Tuna sustainability might be the biggest ocean success story you've never heard about. Nearly 100 percent of global tuna catch is no longer experiencing overfishing, but that didn't happen by accident. There is a hidden system behind the scenes that most people never see, and it is quietly changing how fisheries work around the world. Harvest rules for fisheries are replacing political negotiations with science-based decisions. Instead of arguing every year about how much fish to catch, managers now use pre-agreed rules that respond automatically to changes in fish populations. This shift has helped tuna stocks recover and stay stable, even as global demand continues to grow. Ocean conservation solutions are often criticized for failing, but tuna shows what happens when science, industry, and policy align. In this episode, you will learn how this system works, why it matters for the seafood you eat, and what it tells us about the future of ocean protection. 👉 Follow the show to get daily ocean insights that connect science to real-world impact.
How Do We Know If Tuna Is Running Out?
07-04-2026 | 13 Min.
Tuna fishing is a global industry, but how do we actually know if we're catching too much? Every time you eat tuna, you're relying on a system most people have never heard of: stock assessments. These scientific models estimate how many fish are in the ocean, how fast they reproduce, and how much can be caught without causing long-term damage. Stock assessments are not about counting every fish, they're about making the best possible decisions with imperfect data. Scientists use catch records, fishing effort, and biological information to understand whether tuna populations are healthy or at risk. But the science is only part of the story. In this episode, we break down how tuna stock assessments work, why they are critical for sustainable seafood, and how organizations like ISSF help ensure that decisions are based on science, not just politics. You'll also learn how past failures shaped today's system, and why the future of tuna depends on getting these calculations right. 👉 Follow How to Protect the Ocean for daily ocean science insights.

There is so much information on the ocean and the issues that are affecting it that it can be difficult to find optimism in the future of the ocean. Climate change, overfishing, plastic pollution, water pollution, and coastal development have altered the ocean in ways that have negatively changed the way we use it.
The repercussions of climate change, including the ominous specter of rising sea levels, the relentless march of warming ocean temperatures, and the ominous shadow of ocean acidification, have not only altered the very fabric of our coastlines but have also conjured fiercer storms and summoned floods with growing frequency. The fossil fuel industry may whisper in your ear that the situation is insurmountable, an inescapable fate. However, this podcast is here to unveil a different narrative, one that empowers you to take action. It illuminates the path to change by casting your vote for leaders committed to implementing climate-rescuing policies and by offering invaluable insights into how each of us can shrink our individual carbon footprint.
The grim reality of overfishing casts a long shadow, fueled by governmental shortcomings in the stewardship of both commercial and recreational fisheries. Within the delicate balance of our oceans, every fish population possesses a threshold - a point at which the relentless harvest of fishermen begins to erode their numbers. The management of these aquatic resources is a formidable task, as the elusive currents of the sea often defy easy tracking. Furthermore, the menace of illegal, unregulated, and unreported (IUU) fishing looms large in many nations, adding to the crisis.
Yet, a glimmer of hope shines through the depths. A beacon for responsible consumption emerges in the form of seafood programs, guiding conscientious individuals toward choices that safeguard our oceans. By heeding these programs, you not only savor the delights of sustainable seafood but also become an informed guardian of marine ecosystems.
The relentless scourge of plastic pollution has unleashed an epidemic of death upon the denizens of our oceans. It's a ruthless killer, claiming the lives of hundreds of thousands of marine mammals, majestic sharks, grandiose fish, gentle sea turtles, and the graceful sea birds that soar above. The malevolence of this crisis knows no bounds, with microplastics infiltrating even the remotest depths of the ocean and etching their presence along every coastline.
To mount a defense against this ecological cataclysm, the clarion call for action echoes on the international and national stages. It beckons governments far and wide to adopt resolute policies, wielding the power to outlaw the menace of single-use plastics and demanding the meticulous detoxification of our supply chains. In this grand battle to safeguard our seas, the fight against plastic pollution knows no borders.
The ominous specter of water pollution looms large, a consequence of our thoughtless disposal into the arteries of our planet – our streams, rivers, lakes, and oceans. This callous act reverberates, sending shockwaves through the intricate ecosystems of our coastal havens, where the likes of coral reefs, resilient mangroves, and swaying seagrasses thrive. But alas, this intrusion is not benign; it bears the capacity to corrode and dismantle these vital sanctuaries, the very lifeblood of countless fish and the steadfast guardians of our vulnerable shorelines.
Yet, amidst the unsettling tide of pollution, there emerges a ray of hope. Through individual resolve and visionary government policies harnessed with cutting-edge technology, we can stem this toxic deluge. Water treatment systems stand as stalwart guardians, armed with the ability to sift out the insidious nutrients that fuel destructive algal blooms. The power to heal our waters and preserve the sanctity of our coastal treasures lies within our grasp.
Coastal development, driven by human desires to construct homes or fortify the shoreline against erosion, represents a significant intervention in the natural order. Yet, these changes, while initially confined to the coastal zone, often send ripple effects that extend far beyond their original boundaries, casting a shadow of unintended consequences.
The repercussions of altering coastlines resonate through interconnected ecosystems, occasionally triggering a cascade of events that can inflict profound harm on distant areas. In doing so, this well-intentioned transformation can unwittingly imperil the lives and livelihoods of communities residing in the wake of its impact. It is a stark reminder that our actions along the coast carry a profound responsibility, not just to the immediate environment but to the greater web of life and society that depends upon it.
