Did you know that the contents of that can of tuna sitting in your cupboard can actually be traced back to the waters and boat where the fish was caught? Organizations like the International Seafood Sustainability Foundation (the ISSF) have placed seafood traceability squarely in the 21st century. This week on Sea Change Radio, we speak with the president of the ISSF, Susan Jackson, to learn more about tuna fishing. We look at her organizations partnership model, discuss the viability of maintaining healthy global fish stocks, and talk about some of the challenges facing the industry.

If youve heard natural gas depicted as a more environmentally friendly fuel alternative as compared to traditional oil and gasoline, you are definitely not alone. Unfortunately, its not true. This week on Sea Change Radio, we welcome two researchers from the Center for Climate Integrity, Rebecca Leber and Rebecca John, to discuss their report profiling the natural gas industrys efforts over the past several decades to mislead the public about its products. We examine the dangers of methane gas emissions that were kept quiet for so many years, talk about the powerful messaging behind the word natural gas, and look at how effective the industry has been in positioning natural gas as a bridge fuel to fight climate change.

If youre a parent trying to decide where your child should go to school, youd prefer to have a choice, right? After all, everyone likes to have options. But the appealing rhetoric of school choice is being used by the right-wing to undermine and underfund public schools, while allocating public subsidies to wealthy families. Today on Sea Change Radio we are talking about school vouchers. Currently, eighteen states have a universal private school choice program, and more are likely on the way. But the expansion of the school voucher system has been made with minimal oversight and has led to waste, fraud, and abuse. The cost to public education is tremendous, as public revenue that would otherwise support public schools (which still educate roughly 90 percent of American students) is redirected to private, religious, and largely unregulated institutions. Our guest this week is ProPublica reporter Jennifer Smith Richards who is here to tell us what she has learned about the damaging effects of school vouchers across the country. We look at the history of the concept in the US, examine issues of abuse and discrimination in Arkansas and Florida, and discuss the very powerful messaging tool embedded in the term school choice.

Many listeners are probably familiar with the term misanthrope - combining the Greek misein (to hate) and anthrpos (human), it means someone who doesnt like people (and most of us probably know one or two such folks, for better or for worse). But today we are talking about synanthropes, plants and animals that live and thrive by hanging around human beings in human environments. This week on Sea Change Radio, we speak with Dan Werb, an epidemiologist whos new book Our Wild Familiars: How Animals Are Adapting to Cities and Reshaping the Natural World delves into the fascinating domain of synanthropic creatures. Come dumpster diving with us as we learn more about raccoons, rats, and coyotes and how we are all existentially linked.

In May of 2026, Marshan Camese addressed a Louisiana state senate subcommittee to voice his objection to the elimination of one of Louisianas two majority-Black districts. The moment went viral as Cameses fiery rhetoric captured the feelings of millions of Americans fed up with the status quo. This week on Sea Change Radio, we are joined by Camese as he breaks down the behind-the-scenes story of the speech, discusses some of the inequities that ignite his passions, and talks about why hes hopeful that a positive change is imminent.

What better way is there to recognize the value of the natural world than to spend some quality time outdoors? This week on Sea Change Radio, we speak with environmental journalist Roddy Scheer about his series of field guidebooks, which, incidentally, cover destination hikes as well as city trails. We look at how urban and easy-access trail guides can help raise peoples awareness of their surroundings, get a behind-the-scenes glimpse into what it takes to publish a field guidebook, and discuss some helpful technology for hikers.

When it comes to electric vehicles, we hear a lot more about cars than we do about big rig trucks. The fact is that while Americans are buying electric cars at record rates, the electrification of the US trucking fleet is on a slow roll. This week on Sea Change Radio, we speak with Adam Browning from Forum Mobility, a company that is trying to change that. We look at Forum Mobilitys vision for helping freight companies go electric, get a glimpse of the new electric trucks coming to market, and compare how Americas electric freight fleet compares to others around the world.

If you go to the website of the Pellet Fuels Institute - the industry's trade association, you will see the claim that wood pellets are renewable and clean-burning." But the reality is something quite different - the manufacturing and burning of wood pellets have severe environmental, health, and social impacts. This week on Sea Change Radio, we speak with Danna Smith, the Executive Director of the Dogwood Alliance, about her organization's efforts to keep the wood pellet industry in check and preserve America's southern forests. More specifically, we focus on a campaign between several non-profits that have come together to create tribal and community-owned forests across the South with the goal of revitalizing local economies through eco-tourism and outdoor recreation.

If you remember watching Ginsu knife ads back in the day, youre already well-aware that the hand cant cut a tomato. This week on Sea Change Radio, we take a brief time out from all the ills of the world to learn more about knives. We speak to master knife maker Adam Simha about all things cutting. We discuss the ins and outs of knife maintenance, compare the quality of knife manufacturing across various countries and take a look at his new line of high-end knives.

As we kick off summer, looking forward to school breaks, barbeques and live outdoor music, it can also mean wildfire season and with it, bad air. This week on Sea Change Radio, we revisit discussions with the heads of two companies doing their best to let consumers know if the air they are breathing is healthy. First, we speak with Glory Dolphin Hammes, the CEO of IQAir North America, to discuss how her companys online technology gives us a snapshot of air quality. Then we learn about PurpleAirs unique crowdsourcing model from the companys founder, Adrian Dybwad.
