How To Protect The Ocean

Coastal Economy and Tourism face a serious threat as the US government moves forward with a plan to open more than one billion acres of ocean to offshore oil and gas drilling, a decision that could impact beaches, fisheries, tourism jobs, and coastal communities for decades. This episode explains why this proposal matters now and how it could reshape life along the coasts of California, Alaska, and the Gulf of Mexico. Offshore oil drilling is often framed as an economic benefit, but this conversation reveals a very different reality. Pete Stauffer from the breaks down how tourism, recreation,...

How To Protect The Ocean

Wikie and Keijo Orcas are the last two captive orcas in France, and a major government decision may finally give them a path out of concrete tanks, but the clock is ticking. France has officially backed the Whale Sanctuary Project in Nova Scotia as their future home, yet this announcement does not mean an immediate rescue. In this episode, we break down what France’s move really means, what still has to happen, and why these two orcas remain in limbo despite years of public pressure. Whale Sanctuary Project Nova Scotia represents one of the most ambitious attempts to move captive whales into...

How To Protect The Ocean

US oil and gas drilling is once again at the center of a high-stakes decision that could shape America’s coastlines, marine life, and coastal communities for decades. This episode asks a critical question: should the U.S. lock itself into new offshore drilling just as climate risks and ocean damage are accelerating, or is there still time to choose a safer path for the ocean and future generations? Offshore drilling impacts go far beyond fuel production, and Oceana campaign director Joseph Gordon explains why oil spills are not short-term disasters but long-term crises. One of the most...

How To Protect The Ocean

Deep sea hydrothermal vents reveal a hidden world where life thrives without sunlight, forcing scientists to rethink how ecosystems can exist in extreme heat, pressure, and darkness. Nearly two kilometers beneath the Pacific Ocean, superheated fluids erupt from the seafloor at Endeavour, creating environments that challenge everything we thought we knew about life on Earth and how it survives. Deep-sea hydrothermal vents are not isolated deep ocean curiosities, they actively influence the chemistry of the entire Pacific Ocean. In this episode, scientists explain how minerals and iron released...

How To Protect The Ocean

Climate Solutions for the Ocean are urgently needed as warming seas, biodiversity loss, and ecosystem collapse accelerate faster than most people realize, and one of the most powerful tools may be hiding just beneath the waves. In this episode, Andrew Lewin sits down with Scott Bohachyk, Director of Seaforestation at Ocean Wise, to explore how kelp forests function as underwater life support systems for the ocean, supporting fisheries, stabilizing coastlines, and helping ecosystems recover from climate stress. Kelp forests have declined by up to 50 percent globally, with some regions losing...

How To Protect The Ocean

Tree-Free Products are disrupting industries that have relied on the same wasteful materials for more than a century, and the shift is happening faster than most people realize. In this episode, we explore how Emerald Ecovations produces over 370 sustainable alternatives without cutting down a single tree, dramatically reducing carbon emissions, water use and ocean-bound pollution. Ralph Bianculli shares why legacy companies resist change and how younger decision-makers are pushing corporate purchasing toward genuine sustainability. Sustainable business is more than a buzzword; it is the...

How To Protect The Ocean

Mass penguin die off explained, a crisis that wiped out ninety five percent of some African penguin colonies, raises a heartbreaking question: how does a thriving species fall to fewer than ten thousand breeding pairs and almost no one sees it happening? This episode uncovers the chain reaction that pushed an entire population toward collapse, from vanishing sardines to the brutal timing of the molt that left tens of thousands of penguins starving. One of the most emotional discoveries in the research was that more than sixty thousand penguins died simply because they did not have enough body...

How To Protect The Ocean

Marine Wildlife Victory raises a powerful question: what does it take to finally protect some of the ocean’s most threatened giants, and why did it take this long? In this episode, you will hear how manta rays, devil rays, and several shark species faced years of intense pressure from overfishing and international trade, and why the world finally agreed they needed stronger protection. The emotional turning point comes when we uncover that manta ray gill plates were so valuable in global markets that populations were declining faster than conservationists could respond. Shark Conservation...

Northern Right Whale crisis: For years, scientists and advocates have watched this critically endangered species decline due to ship strikes, fishing gear entanglement, and rapid ocean change. This episode asks a crucial question: Does the first population increase in years signal real recovery or just a temporary pause in a long-term crisis, and what must change now to keep that number rising? Whale conservation stories: Oceana campaigner Nora Ives brings clear insights into how monitoring efforts and shifting whale behavior shape our understanding of their future. She explains how...

Orcas vs Great White Sharks is more than a dramatic headline—it’s a sign of how ocean ecosystems are shifting before our eyes. New drone footage shows orcas in the Gulf of California attacking and killing juvenile great white sharks in what scientists believe are nursery zones. The footage, captured in 2020 and 2022, reveals orcas flipping young sharks onto their backs, inducing tonic immobility, and surgically removing their livers—a precise and efficient hunting technique that may reshape predator-prey dynamics.

For years, scientists have known about great white shark nurseries, but what defines a “true nursery” has always been debated. These new observations raise deeper questions: Are orcas expanding their hunting grounds, or are juvenile sharks moving into new, warmer waters due to climate change? If orcas continue targeting young sharks, could this affect the recovery and stability of great white populations across the Pacific? In this episode, Andrew explores the science, the controversy, and what these interactions mean for the future of ocean conservation.
