Andrew Lewin

I’m Andrew Lewin, a marine biologist turned science communicator who has spent the last 10+ years helping people understand and protect the ocean. My journey started in the field, studying marine ecosystems and working on conservation projects. But over time, I realized that science alone isn’t enough—if people don’t hear the stories, they won’t take action. So I picked up a microphone and started podcasting.

Today, I host How to Protect the Ocean, where I interview scientists, conservationists, policymakers, and community leaders who are making a difference. I’ve published over 1,200 episodes and built a global audience that wants to learn, engage, and act. Along the way, I’ve seen how podcasting can change lives: listeners have left jobs to start ocean nonprofits, returned to school to pursue marine biology, or simply become more mindful stewards of the sea.

I also co-founded The Undertow, a platform that supports independent ocean changemakers and gives voice to those often left out of mainstream conservation media.

If you’re looking for a guest who can speak with passion and clarity about climate, conservation, science communication, podcasting, and what it really takes to make a difference for our planet, I’d love to join your show. I don’t just talk about the ocean—I help people fall in love with it, and empower them to protect it.
