  • Can Fungi Help Heal the Earth?

    Can Fungi Help Heal the Earth?
    2025/12/05
    Across the U.S., there are well over a million contaminated brownfields and superfund sites such as abandoned factories, industrial facilities, and former gas stations where toxic materials have accumulated in the soil. Many of these sites sit polluted for decades because cleanup is expensive and still relies on excavating the soil, hauling it away, and dumping it somewhere else. California alone exports more than half a million tons of contaminated soil every year, much of it to hazardous waste landfills in other states. On this episode of Terra Verde, host Hannah Wilton speaks with environmental toxicologist and mycologist Dr. Danielle Stevenson about nature-based remediation as an alternative to costly “dig and dump” cleanup. Drawing from her research at three highly contaminated brownfields in Los Angeles, Stevenson describes how she works with fungi, plants, and microbes to pull heavy metals from soil, break down petrochemicals, and restore life to polluted sites. Stevenson also discusses her post-fire bioremediation research, where she is using “myco-wattles,” native plantings, and hyperlocal fungal inoculum to rebuild soils in landscapes scorched by the Palisades and Eaton fires.

  • Tackling PFAS in California

    Tackling PFAS in California
    2025/11/21
    Popular for their water- and oil-resistant properties, PFAS are found in countless consumer products, including rain gear. Photo by Gabriel Almanzar. Popular for their water and grease resistance, perfluoroalkyl and polyfluoroalkyl substances (PFAS) are used in countless everyday products, from cookware and cosmetics, to rain gear and cleaning supplies. They are sprayed on crops, added to food packaging, utilized in electronics, and much more. As a result, these substances — which have been linked to serious health impacts and have earned the nickname “forever chemicals” due to their persistence in the environment — are now widespread in our water, soil, and air. Several states have begun to take action on the issue. But the road to PFAS regulation has proven challenging, including in the Golden State. Terra Verde host and Earth Island Journal managing editor Zoe Loftus-Farren speaks with Andria Ventura, legislative and policy director with Clean Water Action, and Bernadette Del Chiaro, senior vice president for California with the Environmental Working Group, about ongoing efforts to reign in our use of these toxic substances California.

  • Youth Leaders Are Shaping the Future of Environmental Policy

    Youth Leaders Are Shaping the Future of Environmental Policy
    2025/11/14
    Youth movements are at the forefront of the fight for a livable future. Around the world, young people are reimagining solutions to urgent environmental challenges and taking bold action to build a more sustainable and just world. On this episode of Terra Verde, host Fiona McLeod is joined by two young environmental leaders — Sophie Tipper and Lily YangLiu — to discuss their work advancing youth representation in environmental policy and decision-making. Lily YangLiu, a 17-year-old from British Columbia, leads initiatives to expand early climate education and increase youth participation in global governance spaces, including the United Nations and international financial institutions. Sophie Tipper, an 18-year-old from Colorado, helped draft and pass a state bill guaranteeing youth representation in environmental justice governance. Both recently received the 2025 Brower Youth Award in recognition of their environmental achievements. Together, they reflect on the power and necessity of youth leadership in shaping a more equitable and sustainable future.

  • A Story of Indigenous Resistance and Renewal from the Klamath River

    A Story of Indigenous Resistance and Renewal from the Klamath River
    2025/11/07
    On this week’s Terra Verde episode, host Hannah Wilton speaks with Amy Bowers Cordalis about her new memoir, The Water Remembers: My Indigenous Family’s Fight to Save a River and a Way of Life. Amy shares stories from the Klamath River and the Yurok homelands, tracing her family’s multigenerational struggle to protect the river, restore the salmon, and defend Indigenous sovereignty. From witnessing the largest fish kill in U.S. history in 2002, to watching the Klamath flow free again after the last dam came down in 2024, Amy reflects on the long arc of loss and healing, and how the river’s restoration offers a model for environmental justice and reconciliation. Amy Bowers Cordalis is a member of the Yurok Tribe, an attorney, fisherwoman, and advocate for Indigenous rights and environmental restoration. She is Co-Founder and Executive Director of the Ridges to Riffles Indigenous Conservation Group, leading efforts to protect tribal sovereignty, lands, and waters—including the historic Klamath Dam Removal project. Former general counsel for the Yurok Tribe and an attorney at the Native American Rights Fund, Amy has earned honors as a UN Champion of the Earth and Time 100 climate leader.

  • How Does Climate Change Affect Our Brains?

    How Does Climate Change Affect Our Brains?
    2025/10/24
    It is widely recognized that climate change is the biggest global health threat that we face today. But one piece of information that gets relatively little attention is the question of: how does climate change affect our brains? Dr. Burcin Ikiz is a neuroscientist and global health advisor who studies exactly that. On this episode, she joins Terra Verde host Fiona McLeod to discuss how climate change and environmental factors like air pollution, extreme heat, and malnutrition affect neurological and mental health. Burcin Ikiz, PhD is the founder of EcoNeuro and the International Neuro Climate Working Group. She leads a network of over 250 researchers, physicians, and policymakers with the goal of expanding research on how climate change impacts neurological and mental health, and on translating these insights into tangible global health solutions. She is an Adjunct Lecturer in the Department of Psychiatry and an Affiliate of the Center for Human and Planetary Health at Stanford University, where she contributes to transdisciplinary efforts linking neuroscience, mental well-being, and climate resilience to advance brain and planetary health. In 2025, Dr. Ikiz was named a Grist 50 Fixer alongside other climate and justice leaders building sustainable and hopeful futures.

  • Managing Groundwater: From Policy to Practice

    Managing Groundwater: From Policy to Practice
    2025/10/17
    California’s 2014 Sustainable Groundwater Management Act (SGMA) was designed to stabilize the state’s groundwater resources, but its implementation has posed significant challenges, particularly for small-scale farmers. Many of these producers across the state face barriers to accessing technical support and taking part in decision-making processes under SGMA. While large agricultural operations can invest in efficient irrigation systems or purchase extra water, small-scale farmers stand to be hit the hardest by water caps and overuse fees. On this episode of Terra Verde, host and producer Hannah Wilton is joined by Catherine Van Dyke, Deputy Director of Water Policy at the Community Alliance with Family Farmers (CAFF), and Ngodoo Atume, SGMA Small Farms Technical Assistance Coordinator with the University of California Agriculture and Natural Resources Small Farms Network. They discuss how SGMA is playing out on the ground and share their insights on how policy actors can work together to ensure the state’s most vulnerable farmers aren’t left behind.
