Threshold

Threshold

Threshold is a Peabody Award-winning documentary podcast about our place in the natural world. Each season, we take listeners on a journey into the heart of a complex environmental story, asking how we got here and where we might be headed. In our latest season, Hark, we hand the mic over to our planet-mates and investigate what it means to truly listen to nonhuman voices—and the cost if we don't. With mounting social and ecological crises, what happens when we tune into the life all around us? Threshold is nonprofit, listener-supported, and independently produced.

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?

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 wi...

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.

A name is essential to your identity. It’s what people call you and what you respond to—it’s part of what you understand about yourself. But do other living things call each other by names? In this episode, we look at how names work in some non-human worlds.
