    Threshold Conversations: Climate Emotions with Audrey Martin

    All over the world, small groups of complete strangers are getting together to share their feelings about climate. These gatherings are called Climate Cafes, and they’re carving out space for some big emotions we might prefer to avoid. But what if talking about our feelings can also help us  address the climate crisis? 

    Audrey Martin is a Bay Area psychotherapist and one of the leaders of the Climate Psychology Alliance of North America. She also happens to be Amy Martin’s sister. Audrey joins us to unpack some of our complicated, scary emotions around climate, and to make the case for why this kind of self-reflection isn’t just comforting—it’s crucial.

    Threshold Conversations: The Roadless Rule with Ben Goldfarb

    Last June, the U.S. the Secretary of Agriculture announced that the Trump administration intends to repeal something called the “Roadless Rule”—a policy implemented in 2001, which protected some of the Forest Service’s wildest lands from logging, mining, and road-building. 

    Author Ben Goldfarb examined the impacts of road and roadless areas in his 2023 book, Crossings: How Road Ecology is Shaping the Future of Our Planet. We talk with Ben about why our Forest Service lands already have so many roads, and what building more would actually mean for wildlife and for people.

    Humans have filled the world with so much noise that the only sounds many of us often hear  on a daily basis are  our own. But all this sound isn’t great for our planet mates and it isn’t great for us either. In this episode, we look at how human-made sound makes it hard for other creatures to listen and communicate.

    Hark | 11 | Am I Not Lucky?

    Modern humans emerged into a world filled with and shaped by elephants. But for elephants, living with humans isn’t always easy. Elephants have survived by adapting to all the changes we’re making to their world. But there’s only so much they can do. In this episode, we look at how we can learn to live with—and listen to—elephants.

    More than 60 million years ago, an asteroid hit the Earth, wiping out almost all the dinosaurs. But one group made it through—the ancestors of birds. In this episode, we look at how these ancient creatures learned to listen and communicate, and how listening to birds has changed us.
