Ocean with David Attenborough: Why There’s Still Hope for the Sea
How To Protect The Ocean
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...

How Harmful Algal Blooms Are Poisoning California’s Marine Wildlife
How To Protect The Ocean
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...

From Oceanographer to Eco-Baker: Maddie Hamann on Building a Sustainable Bread Brand to Help Protect the Ocean
How To Protect The Ocean
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...

Why Nearshore Ocean Conservation Is Critical for Climate, Biodiversity, and Communities
How To Protect The Ocean
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...

Why Gray Whales Are Dying: Climate, Starvation, and Human Threats
How To Protect The Ocean
Gray whales are dying along the Pacific coast—and the reasons are alarming. In this episode, we dive into why hundreds of gray whales have stranded or died between 2019 and 2023. From food shortages in their Arctic feeding grounds to the rising risks of ship strikes and entanglement in fishing gear, we break down what NOAA has called an Unusual Mortality Event (UME) and how climate change is accelerating the crisis. We also explore recent signs of population recovery and what it means for the future of marine mammal conservation. If you want to understand how ocean ecosystems are...
info_outlineCoral restoration is often seen as a beacon of hope for our oceans—but are we putting too much faith in it? In this episode, we dive into why coral bleaching has become an annual event, especially on the Great Barrier Reef, and whether restoration can keep up with the pace of climate change. We explore what recurring stress events mean for the long-term survival of reefs and how restoration, while helpful, might be insufficient if larger systemic issues like warming seas and pollution aren’t addressed.
Restoration is discussed not just as a solution, but as a strategy that needs to be reconsidered in light of the science. What happens when reefs bleach four years in a row? What’s the ecological and financial cost of trying to rebuild what’s actively being destroyed? This episode challenges listeners to rethink what ocean conservation should prioritize in the fight for the future of coral reefs.
