    It's All Elementary: Part 3 – Carbon

    07/02/2026 | 31 mins.
    This is part 3 of our three-part series about elements. And today is a biggie: carbon. When we hear about carbon, it's usually about its role in heating up the planet. And while that's an absolutely critical part of the story, the story of this most miraculous of substances is so much larger. 
    We talk to Peter Brannen, author of The Story of CO2 is the Story of Everything, about how carbon has always been central to just about every major turning point in the history of life on Earth...including why life is here in the first place.

    It's All Elementary: Part 2 – Phosphorus

    06/18/2026 | 36 mins.
    This is part 2 of our 3-part series about elements.  Last time we met nitrogen, today, it’s partner in crime and in life – phosphorus.  
    WLRN Environment Editor Jenny Staletovich has gotten to know the main character of this story pretty well after reporting on the environment in South Florida for more than a dozen years. Bone Valley in Central Florida has quietly fed the world’s hunger for phosphorus, even as its waters, in particular the Everglades, suffer from the fallout. 
    In this episode, you'll meet fishing captains turned environmental crusaders, hear about Guano Wars fought over this "Devil's Element," and learn how some are figuring out how to fix our phosphorus paradox.

    It's All Elementary: Part 1 – Nitrogen

    06/05/2026 | 25 mins.
    In this three-part series, we’re giving some of the most misunderstood characters on the periodic table a fuller story. We dive into the fascinating double lives of these elements that are both the makers and unmakers of our world. 
    In part one, reporter Olga Loginova travels to Cape Cod to meet nitrogen. In this episode: we trudge through the marsh, avoid great white sharks, and find out how we harnessed the power of nitrogen, why that power turned against us, and what we can do about it.

    Losing Paradise

    05/06/2026 | 46 mins.
    Why are fishermen being arrested in Louisiana? An epic battle over "Sportsman's Paradise" is being waged on Louisiana's water. This is a story about public rights and private power colliding. As more and more of Louisiana’s coast disappears underwater, the state’s two most powerful and iconic forces – fishing and fossil fuels – are waging war over who owns the drowned land.
