Ocean recovery is not just possible, it’s already happening in places where we’ve taken action. In this episode, I dive into Ocean with David Attenborough, a documentary that reminds us of the ocean’s incredible resilience. From thriving coral reefs to fish populations bouncing back, the film offers powerful proof that when we give marine ecosystems space and protection, they can heal faster than we think. It’s a rare example of ocean storytelling that balances urgency with genuine optimism.

Bottom trawling, however, threatens that progress. The documentary pulls back the curtain on this destructive fishing method, revealing how vast swaths of ocean floor are scraped clean, alongside the fish, sharks, and invertebrates that live there. The fishing industry’s backlash has been swift, but the film doesn’t dwell on blame. Instead, it shows us that even in damaged habitats, life can return when given the chance. The hope is real—but only if we act now.

Tide gauges are a critical yet often overlooked tool in our fight to understand and respond to climate change. In this episode, Dr. Andrew Thaler returns to the podcast to share a powerful story about installing a tide gauge in his hometown of St. Michaels, Maryland. He breaks down how this simple device provides crucial data for flood risk, sea level rise, and community resilience, bringing science closer to home.

Community science is at the heart of Dr. Thaler’s work. We explore how grassroots efforts, low-cost technology, and open-source tools empower residents to monitor and respond to environmental changes themselves. Whether you’re a policymaker, scientist, or citizen concerned about the impacts of coastal flooding, this episode will deepen your understanding of how data can drive change from the bottom up.

Harmful algal blooms are wreaking havoc along the California coast, releasing toxic domoic acid that is poisoning marine life. In this episode, we explore how this naturally occurring toxin is causing mass die-offs in sea lions, dolphins, and seabirds, and why climate change and nutrient pollution may be making these blooms worse. You’ll hear about the science behind domoic acid, its neurological effects on animals, and how it mimics epilepsy symptoms in marine mammals.

Domoic acid poisoning is becoming a more frequent and devastating threat to ocean ecosystems, pushing wildlife rescue centers to their limits. We discuss the broader implications of this crisis on marine conservation efforts and public health, and what we can do to protect vulnerable species as ocean temperatures rise. This is not just a marine science issue—it’s an urgent conservation challenge that demands our attention.

Ocean conservation isn’t always about what’s happening in the water—it’s also about the choices we make on land. In this episode, we speak with Maddie Hamann, a former oceanographer turned sustainable food entrepreneur. Maddie shares how her background in ocean science led her to co-found PACHA, a company that creates sourdough buckwheat bread using organic, regenerative practices. From nutrient cycles to sustainable packaging, Maddie explains how oceanography continues to inform her mission—even in the kitchen.

Sustainable food systems play a major role in protecting marine environments. Maddie breaks down why she and her partner chose buckwheat, how they built an ocean-friendly food brand, and how consumers can support businesses that align with ocean values. This conversation goes beyond the surface, connecting science, health, and sustainability in a delicious way.

Plastic pollution in the Maldives has become a serious environmental crisis, despite the nation’s image as a pristine paradise. In this episode of How to Protect the Ocean, host Andrew Lewin shares the inspiring story of Zazou Saeed—a young Maldivian surfer and ocean advocate—who rose to become a local conservation hero by campaigning against single-use plastics. From leading beach cleanups to working with NGOs like Save the Beach and Parley for the Oceans, Zazou sparked a grassroots movement that helped influence national policy.

Ocean conservation through local action is a powerful force. Zazou used art, storytelling, and education to mobilize Maldivian youth and drive home the consequences of plastic pollution on coral reefs, sea turtles, and marine life. Her efforts were instrumental in shifting public awareness and building momentum toward the Maldives’ plastic bans. This episode highlights how one passionate person can make a massive difference for their community—and the ocean.

Orca conservation takes center stage as we highlight an inspiring community-led effort to protect these iconic marine mammals. Andrew explores how nearshore ocean heroes are driving real change, and why their stories matter more than ever. Learn how protecting your local waters can lead to healthier oceans worldwide—and why it’s time we recognize those leading the charge.

Shark encounters on social media spark a deeper discussion on wildlife ethics, as Andrew reacts to a TikTok video that demonstrates exactly what not to do. Wrapping up the episode is a look at David Attenborough’s new film “Ocean”, including an eye-opening sequence on bottom trawling and what it reveals about modern ocean challenges. Whether you’re an ocean lover or new to marine conservation, this episode offers compelling stories that educate and inspire.

Nearshore conservation is often overlooked in favor of flashy offshore marine protected areas. But a growing movement of community-led initiatives is showing that protecting coastal waters might be one of the smartest, most effective ways to safeguard ocean biodiversity and build climate resilience. This episode explores new insights from the Nearshore Ocean Progress report by the Center for American Progress, which highlights successful local conservation efforts across the U.S.

Community-driven ocean protection has the power to achieve more than top-down mandates. By focusing on the waters closest to home—estuaries, reefs, salt marshes, and seagrasses—coastal residents are preserving biodiversity, supporting livelihoods, and defending their homes against sea-level rise and extreme weather. Learn why investing in these initiatives may be the most impactful ocean action you can take.

Deep sea mining in the U.S. is entering a new chapter after a recent executive order signed by former President Donald Trump authorized exploration and extraction not only in U.S. Exclusive Economic Zones but potentially in international waters. This move marks a dramatic shift in ocean policy and raises serious questions about compliance with the United Nations Convention on the Law of the Sea (UNCLOS), which governs activities beyond national jurisdiction.

The risks of deep-sea mining are substantial. From disturbing unique and fragile ecosystems on the ocean floor to triggering global geopolitical tensions, the implications stretch far beyond resource extraction. Marine biologist Dr. Andrew Thaler joins the show to explain the science behind deep-sea habitats, the governance gaps in current policy, and why this executive order could undermine decades of international ocean conservation work.

This episode examines the legal, environmental, and political aspects of U.S. deep sea mining efforts. Listeners learn what’s at stake, who is challenging the decision, and how this could affect the global push for sustainable ocean management. If you care about the future of deep ocean ecosystems and global cooperation, this episode is essential listening.
