On April 16 the US Senate voted to reverse a moratorium on mining near the Boundary Waters Canoe Area Wilderness in Minnesota, a million acres on the US-Canada border that’s teeming with wildlife and crystal-clear waters. For years a Chilean company has proposed to extract valuable copper, nickel, and cobalt there using copper sulfide mining. Democratic Senator from Minnesota Tina Smith speaks with Host Jenni Doering about why in her view mining in the same watershed as the Boundary Waters is not worth the risk.

While electrifying transportation is essential to addressing the climate crisis, the mining of nickel, copper, and lithium required to build out these green technologies brings its own environmental and social costs. To understand these impacts, author and political scientist Thea Riofrancos traveled to the Atacama Desert in Chile, home to one of the largest lithium reserves in the world. She joins Host Paloma Beltran to discuss her book, Extraction: The Frontiers of Green Capitalism.

Nigerian conservation ecologist Iroro Tanshi rediscovered the short-tailed roundleaf bat in 2016, after decades when it was believed extinct in the region. The species is still critically endangered, with habitat loss from wildfires as one of its top threats. So Iroro joined with local groups to start a community-led program to develop safer field burning practices and wildfire fighting strategies. Iroro Tanshi is the recipient of the 2026 Goldman Environmental Prize for Africa and talks with Host Jenni Doering.
