Short-Form Content for Ocean Awareness: What Actually Works

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

The Electric Boat Revolution Is Here

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.

3 For-Profit Companies Cleaning the Ocean and Paying Living Wages

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

How 4ocean Turned Bracelets Into 50 Million Pounds of Ocean Trash Removed

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.

Why Cargo Ships Are Bringing Back Sails to Cut Emissions

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

Can Hollywood Go Green? Inside the Sustainable Production Movement

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.

Greenwashing Exposed: Why 400+ Companies Got Caught Lying About Sustainability in 2026

Businesses love to say they are sustainable. Andrew breaks down why that word is no longer enough on its own. A new EU consumer protection regulation now requires companies to prove environmental claims with evidence, and it has helped drive more than 400 greenwashing-related enforcement actions across the US, UK, EU, Canada, Australia, and India in 2026 alone. Andrew draws on his own university experience with food labeling regulation to explain how vague standards let companies technically co

People and Sustainability: The Human Cost Big Business Keeps Ignoring

Sustainability conversations usually center on ecosystems, emissions targets, and corporate pledges, but this episode makes the case that people belong at the center of that conversation too. Andrew looks at how communities living closest to refineries, extraction sites, and industrial waterfronts carry a disproportionate share of the pollution burden, often without having consented to the risk in the first place. Using a Philadelphia refinery as a case study, Andrew walks through how fenceline

Why Sustainable Companies Actually Save Money

Sustainability isn't just good PR; it's good business math. In this episode, Andrew breaks down why companies are shifting toward circular business models, using Philips Lighting as a case study in selling light as a service instead of a product. He digs into the economics behind the shift: a British industrial symbiosis study that saved companies significant money and cut CO2 emissions, a PwC Sweden study showing double-digit operating cost reductions in circular electronics, and the rise of su
