This week on The Temple of Surf Podcast, we swim into the world of ocean conservation with one of the most passionate defenders of marine life David McGuire, marine biologist, filmmaker, and founder of Shark Stewards. Known to many as “Shark Stewards Dave”, McGuire has dedicated his life to protecting sharks and restoring healthy ocean ecosystems. From the wild waters of California to the coral reefs of the Indo-Pacific, his mission is clear: to save sharks and safeguard the balance of the sea.

Sharks have been swimming our oceans for over 400 million years, yet today they face one of the most severe threats in their long evolutionary history, overfishing, habitat loss, and the cruel practice of shark finning. Through his non-profit organization Shark Stewards, David has been on the frontlines of this battle, successfully helping to pass legislation banning the shark fin trade in several U.S. states, and working internationally to promote sustainable fisheries and marine protected areas.

In this inspiring conversation, we explore how David’s journey from ocean explorer and filmmaker led him to become a leading voice in marine advocacy. We talk about his early encounters with sharks, his documentaries for National Geographic and other media, and the moment he realized he could no longer stand by while these incredible animals were disappearing from our oceans. His passion is contagious, and his stories remind us that every one of us surfer, diver, or ocean lover has a role to play in protecting the blue heart of our planet.

We also discuss how sharks are misunderstood creatures, often feared rather than respected. David breaks down the myths surrounding shark attacks and shares how media sensationalism has distorted our view of these apex predators. In reality, sharks are essential to the health of marine ecosystems. Without them, the delicate balance of the ocean collapses. Through education, science, and storytelling, Shark Stewards works to replace fear with understanding and action.

From the great whites cruising California’s coast to the reef sharks of the South Pacific, David’s insights illuminate the complex relationship between humans and the sea. This episode isn’t just about conservation, it’s about connection. It’s a reminder that protecting sharks means protecting the very waves we ride and the oceans that define our culture as surfers.

Tune in to this episode of The Temple of Surf and be inspired by David McGuire’s vision of a future where sharks still roam free, coral reefs thrive, and the ocean remains wild and alive for generations to come.
