   Number 1: Arguing With the Wind: A Spiritual Journey in Wilderness

   As a teenager, Walt McLaughlin told his parents he'd been talking to God in the woods, and he ended up in a psychiatric ward on Thorazine. Years later a philosophy degree had done nothing to assuage his existential anxiety, so he hitchhiked west — and eventually flew alone into Alaska's Endicott River Wilderness with a .44, no radio, and two-and-a-half-weeks worth of food. On this episode of Constant Wonder, the writer and erstwhile hiking guide tells host Marcus Smith how a death wish that had shadowed him since adolescence finally broke — on a rain-soaked escarpment, with a raven croaking at him from a branch — and how he came to accept that the world is harsh yet beautiful. Walt McLaughlin lives in northern Vermont, close to the New England woods and wilds he loves. There he's proprietor of the small indie press Wood Thrush Books, online at woodthrushbooks.com. This episode includes a first-person account of depression and a suicide attempt. Guest: Walt McLaughlin, publisher and author, “Cultivating the Wildness Within”; “Arguing with the Wind: A Journey into the Alaskan Wilderness”; and “Confronting the Unknowable: Essays on God, Nature and Being Human”

   Number 2: Protecting Humans, Protecting Wildlife

   What if protecting humans is the key to protecting wildlife? In this episode, Dr. Gladys Kalema-Zikusoka tells host Marcus Smith how people living near African nature preserves can unknowingly pass illnesses to nearby mountain gorillas—and how she's working with local communities to shield these endangered animals from disease and habitat loss. As Uganda's first wildlife veterinarian, Kalema-Zikusoka pioneered the use of "One Health" in gorilla conservation—an approach that treats human, animal, and environmental health as interconnected, rather than separate concerns. By investing in the health and economic security of nearby communities, she keeps gorillas healthy too. The payoff is a thriving gorilla tourism industry that benefits the entire country.

   Number 3: Floral Revolutionaries: Plants as Planet-Makers

   Flowers, believe it or not, are nature's greatest revolutionaries. In this episode of Constant Wonder, biologist David George Haskell and host Marcus Smith discuss how flowers turned enemies into allies and used ultra-precise adaptations to survive an intensely competitive natural world. By exploring the floral connections that draw him closer to his mother and great-great-grandfather, David also examines how flowers have changed in just a few short decades. He makes the case for following a single bloom's growth and decay over the course of several months, and describes the benefits of keeping a floral diary—an easy way for anyone to become more attentive to the subtle turning of the seasons.

   Number 4: Fiddling with the Heart: Gaelynn Lea's Fearless Sound

   Gaelynn Lea plays the violin like a cello — a technique she discovered almost by accident, one that would eventually carry her from a small-town orchestra to NPR's Tiny Desk Concert and, later, to composing the original music for Broadway's revival of Macbeth, starring Daniel Craig and Ruth Negga. In this episode of Constant Wonder, she talks with Marcus Smith about her unconventional technique, the unexpected opportunities it opened up, and how her songwriting continues to evolve. Gaelynn Lea was born into a family of artists, with musical parents and an early start in youth theater. But everything changed in elementary school, when an orchestra teacher encouraged her to try holding the violin like a cello — a small discovery that would shape the rest of her career. Guest: Gaelynn Lea is a violinist, songwriter, composer, disability advocate, and author of "It Wasn't Meant to Be Perfect: A Memoir." Photo credits to Mike Madison

   Number 5: The Wondrous, History-Shaping World of Parasites and Predators

   Dino Martins is an entomologist who finds beauty in every bug. In this episode of Constant Wonder, he tells host Marcus Smith about his passion for parasites and how a lifetime of studying creepy-crawlies draws on both scientific and spiritual knowledge. Dino Martins grew up in Kenya, surrounded by wildlife and the insects that feed on them. Seeing parasitic wasps colonize caterpillars taught him the value of paying close attention, and he can enthrall even a skeptic with the marvels of the tsetse fly. He winningly argues that parasites and other predators are full of wonder and worthy of our fascination.
