Many listeners are probably familiar with the term misanthrope – combining the Greek misein (to hate) and anthrōpos (human), it means someone who doesn’t 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...

In May of 2026, Marshan Camese addressed a Louisiana state senate subcommittee to voice his objection to the elimination of one of Louisiana’s two majority-Black districts. The moment went viral as Camese’s 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 ...

Imagine you jumped in a time machine and went back 15 years. You might get a chuckle seeing the flip phones and watching masses of people on that thing we used to call a “work commute,” but you might not think twice about the slightly cooler temperatures. If you set the machine to go back a century, however, you would probably want to pack an extra sweater. This week on Sea Change Radio, we speak with author and environ...

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 people’s awareness of their surroundings, get a behind-the-scen...

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 Mobility’s vision for helping freight companies go el...

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 Do...

If you remember watching Ginsu knife ads back in the day, you’re already well-aware that the hand can’t 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 ...

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 company’s online techn...

In 2016, the leader of the MAGA cult (who believes that climate change is some sort of hoax) incorrectly referred to the EPA as the “Department of Environmental Protection,” then vowed to, “get rid of it in almost every form.” After listening to this week’s guest on Sea Change Radio, you might think that getting rid of the EPA actually would have been preferable. Rather than protecting the environment,...

Several times a day I find myself noting that this administration stinks. It turns out it’s not just the stench of cruelty, chaos, and corruption – it’s air quality issues, too. This week on Sea Change Radio, we are joined by ProPublica reporter Lisa Song to learn how the Trump administration is affecting the air we breathe. First, we discuss Song’s reporting on the EPA’s roll-back of air monitoring sy...

If you haven’t yet personally witnessed the very odd feeling of driving up to a four-way stop sign only to realize that the vehicle across the street from you has no driver behind the wheel, chances are you will soon enough. Like it or not, autonomous vehicles are coming, and this week on Sea Change Radio we are speaking with Samuel Abuelsamid, an expert on self-driving technology. We take a look back at the evolution of...

The recent Supreme Court ruling Louisiana v. Callais not only eviscerated Section 2 of the Voting Rights Act and allowed states to enact discriminatory maps with impunity, it was also a brutal reminder that despite record low approval ratings for the current president, reversing the negative impacts of this administration will be a big job. This week on Sea Change Radio, we enjoy a wide-ranging political conversation with John Stoe...

Copper and steel were pivotal to the industrial revolution. But these days, it’s clear that continued reliance on these substances as our key building materials has devastating environmental implications, including habitat destruction from open-pit mining, water toxification from acid mine drainage, and air pollution from sulfur dioxide emissions. Fortunately there’s an emerging array of cutting-edge materials...

For decades, Republicans have been echoing the same mantra, that “government is not the solution, it’s the problem.” And for the most part, when the GOP is in power, this aphorism sadly rings all too true. This week on Sea Change Radio, we speak with Ann E. Carlson, an environmental law professor and former head of the National Highway Traffic Safety Administration about her new book, Smog and Sunshine: The Surpri...

Most of us aren’t aware of just how much carbon dioxide is emitted from biomass waste such as sawdust, forest thinnings, and agricultural residuals but woody biomass energy production emits roughly double the carbon pollution per unit of electricity of coal, and 4.5 times that of gas. This week on Sea Change Radio, we speak to Hannah Murnen, the Chief Technology Officer at a carbon dioxide removal startup known as Graphyte to...

With all the havoc the Trump administration is currently wreaking on humanity, it’s easy to forget the threat this reign of terror poses for wildlife, as well. Luckily, there are still many people fighting the good fight to protect vulnerable flora and fauna. This week on Sea Change Radio, we speak with Ryan Shannon, a Senior Attorney at the Center for Biological Diversity. We discuss the landmark case he helped argue to prot...

If you’re still driving a combustion engine vehicle, you’ve probably noticed that within a matter of weeks the price of gas has increased by about a third, courtesy of the illegal war being waged on Iran by the US and Israel. This week on Sea Change Radio, we welcome returning guest and oil expert Daniel Dicker to get an inside perspective on the latest spike in the global price of oil. We discuss the impact the hi...

Even casual fans of Formula One, or F1 Racing may have noticed that the popular motor sport has annual grand prix events spanning the globe, from Baku to Shanghai to São Paulo. And this calendar, our guest on this week’s Sea Change Radio argues, comprises a larger portion of F1’s greenhouse gas emissions than the racing itself. Today we speak with Alexis Normand, the CEO of Greenly, to discuss his company’s new re...
