Amy Martin is the founder and executive producer of Threshold, a podcast and public radio program. Each season, Threshold takes a deep dive into one story of pivotal change in the natural world. Season one told the story of the American bison. Season two takes listeners to all eight Arctic countries to learn about climate change through the eyes of local communities. Season two selections aired on public radio stations around the U.S. via PRI’s The World. The program received major support from the Pulitzer Center, Montana Public Radio, The Park Foundation, and from Threshold listeners. Martin has presented her work at the International Wildlife Film Festival, via the TEDxstage and at campuses including the University of Missouri, Xavier University of Louisiana and her alma mater, Augustana College.
