The How To Protect The Ocean is your resource to keep you informed on the latest ocean news; teach you how to speak up for the ocean; and, how you can take action to live for a better ocean. 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.

Green sea turtle conservation: How one species' recovery gives hope amid a sea of decline

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.

Fighting overfishing with AI: Satellites Expose Illegal Fishing in Marine Protected Areas

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.

Great White Shark Populations Have Interesting DNA

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.
