Today marks episode 2000 of How to Protect the Ocean, and Andrew is taking a break from the usual format to look back at how this show came to be. From an accidental start in 2010 to a name change driven by search engine optimization, to over 3 million downloads across 11 years, this episode traces the full arc of the podcast's history. Andrew also opens up about how podcasting reshaped his career. What started as a side project outside of work hours led to TV documentary appearances, podcast h

Podcasting has been part of Andrew Lewin's life for 11 years, and in this episode he explains why he thinks more people working in ocean science and conservation should be doing it too. He walks through what makes long-form audio and video different from the short clips discussed in yesterday's episode: the ability to sit with complex topics, tell a full story, and reach an audience that's multitasking, whether they're walking the dog, working out, or gardening while listening. Andrew gets spec

Walking sharks are one of the strangest small predators on the reef: pectoral fins built for crawling across coral flats at low tide, distributions so narrow some species live in a single bay, and a family tree that's still being filled in. In this episode, Andrew Lewin and Dr. David Ebert are joined by Jess Blakeway, a PhD candidate at the University of the Sunshine Coast, whose research on the distribution, ecology, and biology of walking sharks (genus Hemiscyllium) in Papua New Guinea has alr

This week on the How to Protect the Ocean podcast, Andrew kicks off a science communication series exploring how ocean advocates can spread awareness across every major content format. Today's episode digs into short-form video: TikTok, Instagram Reels, and YouTube Shorts, and what it actually takes to make original content work when you're used to talking for an hour, not ninety seconds. Andrew is candid about his own struggle with the format, since most of his short-form output today is repurp

Electric boating is having its Tesla moment, and few people understand that shift better than Alexandre Mongeon, CEO and co-founder of Vision Marine Technologies. Andrew sits down with Alexandre to trace his path from importing speed boats in Montreal to building the electric outboard systems now powering boats across North America. Along the way, Alexandre shares how a chance meeting with Olympic sailor and boat designer Ian Bruce set him on the road to electric propulsion, and how a rental-to-

Not every ocean conservation win comes from a nonprofit or a government program. In this episode, Andrew breaks down three for-profit companies that are cleaning up the ocean, funding wildlife research, and paying living wages to the people doing the work. These businesses show that conservation and profit are not opposing goals. They can be the same goal. Andrew covers 4Ocean, whose full-time captains and cleanup crews earn living wages with health insurance and bonuses across Florida, Bali, H

4ocean has removed more than 50 million pounds of plastic and trash from the world's oceans, rivers, and coastlines. That milestone did not come from a government program or a traditional nonprofit. It came from a for-profit business built around a single idea: every bracelet sold funds the removal of a pound of ocean trash. In this episode, Andrew breaks down how 4ocean went from one viral video in Bali to a global cleanup operation, why founders Alex Schulze and Andrew Cooper chose a business

The boat rental market is bigger than most people realize, and it's growing fast. In this episode, Andrew shares a personal story about his dad, boats, and why he's spent the last few months considering buying one, before walking through the data that changed his mind about ownership altogether. Andrew breaks down the numbers behind the boat sharing economy: a market valued between nineteen and twenty three billion dollars US, growing five to seven percent a year, with electric propulsion emerg

Global shipping moves roughly 80 to 90% of the world's trade, and it comes with a real climate cost: the industry is responsible for a little over 2% of global CO2 emissions. On today's episode of the How to Protect the Ocean Podcast, Andrew looks at one of the more surprising fixes the industry is turning to: sails. Not the old canvas kind, but massive rigid wing sails retrofitted onto modern cargo vessels to cut fuel use and emissions without waiting on next-generation fuels. The centerpiece

Hollywood might not be the first industry you think of when it comes to protecting the planet, but film and TV production has been quietly transforming how it operates behind the scenes. In this episode, Andrew sits down with Zena Harris, founder and president of Green Spark Group and co-host of The Tie-In podcast, to unpack what sustainability actually looks like on a working film set. Zena walks through the surprising ways major productions are cutting fuel consumption, swapping diesel genera
