Perfluoroalkyl and polyfluoroalkyl substances—commonly known as PFASs and "forever chemicals"—have become ubiquitous in the environment and are being found almost everywhere in soil, water, plants and bodies. The Trump Administration has lowered drinking water standards for PFASs presence but that does not mean the stuff has gotten safer. You might know PFASs in the form of Teflon which, for many years, are applied to non-stick cookware so those eggs slide off the pan. But if you overheat that pan, the Teflon might also slide off. PFASs slide off of many other things, as well. The environmental and health impacts of PFASs are almost totally unknown, although they are beginning to look pretty bad.Join host Ronnie Lipschutz for a conversation with Dr. Faith Kibuye, a Water Resources Extension Specialist in the Department of Ecosystem Science and Management and the Institute of Energy and the Environment at the Pennsylvania State University. Kibuye specializes in environmental engineering, focusing on water quality, aquatic chemistry, cyanobacterial blooms, and contaminants like pharmaceuticals and PFASs, and their fate, transport and transformation.

Indigenous peoples around the world are under threat, especially from massive development projects engineered by governments and corporations, which promise to destroy the lands, forests and waters on which those peoples depend. In an article that appeared in a recent issue of The New York Review of Books, “We Think They'll Kill Someone” journalist Anjan Sundaram reported on one such project in the Southern Mexico Oaxacan town of San Blas Atempa, where a new factory will wipe out a communally owned forest.Join host Ronnie Lipschutz for a conversation with Sundaram. He is an Indian author, war reporter, academic, television presenter and founder of The Stringer Foundation. He is the author of three memoirs of journalism, Stringer, Bad News and Breakup. His forthcoming book, Double Exposure: Two Reporters in the Climate War, is scheduled for publication this coming fall.

The world’s cities are big and getting bigger. By 2050, 80% of the world’s people will live in cities. Can cities be made sustainable? Who is thinking about this? Join host Ronnie Lipschutz for a conversation with Peter Calthorpe, architect and urban designer with HDR, a global company specializing in architecture, engineering, environmental and construction services. Over the past 45 years, Calthorpe has been a primary advocate for sustainable communities, the New Urbanism and transit-oriented development. His most recent publications are "Ending Global Sprawl: Urban Standards for Sustainable and Resilient Development" for the World Bank and “Grand Boulevards and the AB2011 Revolution: Reinventing the Strip to Solve California’s Housing Crisis.”

The removal of four dams from the Klamath River in Northern California is rapidly becoming one of the great recent success stories in conservation and restoration. The riverbank habitat is returning to its former condition and salmon have been spotted swimming upriver past the sites where the dams once blocked their passage. Along with this comes the restoration of the indigenous peoples’ way of life, heavily dependent on those fish. Join Host Ronnie for an update on the Klamath in a conversation with Amy Bowers Cordalis, who has just published The Water Remembers—My Indigenous Family’s Fight to Save a River and a Way of Life. She is a mother, fisherwoman, attorney, executive director of Ridges to Riffles, and member of the Yurok Nation and its former general counsel. (Photo by Brontë Wittpenn, San Francisco Chronicle)

Nuclear weapons have been with us for 80 years. There are fewer today than was the case at the height of the Cold War, but there are more countries with nukes than ever before. Some heads of state have been, of late, threatening to use them. If you’ve seen Kathryn Bigelow’s recent film, “House of Dynamite,” you’ll know that human psychology is the linchpin on which the entire system of nuclear deterrence rests: would the President (or Premier or whatever) exchange their capitals for others? Trade Washington, DC for Moscow or Beijing?There is reason to be concerned about this question: The United States is planning a $1.7 trillion overhaul of its entire nuclear arsenal, designing new warheads and investing in new bombers, missiles, and submarines to carry them, all in the name of “modernization.” It’s not that the current generations of platforms and warheads won’t work; it’s more that Admirals, Generals and Presidents don’t trust devices put into operation when they were very young and that there is a lot of money and prestige in having the latest generation of gadgets and lording that over the competing services. Oh, and new weapons are “manlier” than the old ones.Join host Ronnie Lipschutz for a conversation with Dr. Dylan K. Spaulding a senior scientist in the Global Security Program of the Union of Concerned Scientists. His work focuses on technical issues related to nuclear stockpile stewardship and policies that can reduce the threat posed by nuclear weapons. He recently authored a UCS report entitled “Plutonium Pit Production--The Risks and Costs of US Plans to Build New Nuclear Weapons.” Its focus is on the stuff that makes warheads go “boom” but along the way, Spaulding covers a lot of other ground and the report is a good primer on nuclear weapons.

Lake Tahoe is one of California’s natural jewels but it is under siege and increasingly awash in plastic wastes, as visitors carelessly dispose of bottles and packages and discarded items degrade into small pieces washed into the lake. What happens to that stuff? As we have been learning, microplastics are everywhere, in the environment and in our bodies. What are their impacts on people, animals and nature? Join host Ronnie Lipschutz for a conversation with Madison “Madio” Wallner, a UCSC PhD student in Environmental Science, who is studying microplastics and tire particles in Tahoe’s bottom sediments.

If you venture out into parks, farms and gardens with various flowering species, you are almost sure to see European honeybees flying about. When we think of bees, those are the ones that usually come to mind. But there are more than 1,600 native bee species in California alone, and many of those are threatened with extinction. Krystle Hickman is a National Geographic Explorer, conservation photographer, and native bee expert who uses her photography to raise awareness about the decline of native bee species and their complex ecosystems. Her new book, The ABCs of California Native Bees, a compendium of text about and stunning photos of native bees in their California habitats, has just been published by Berkeley's Heyday Books. Learn how a conservation photographer goes about her work and how she finds those bees.

Even before the publication of Paul Ehrlich’s The Population Bomb in 1968, we heard warnings that humanity would be doomed to a future of famine, hunger and starvation unless industrial agriculture were unleashed to grow food as efficiently as possible in every nook and cranny of the world’s arable lands to feed the “ten billion.” Those warnings continue today. But is it correct? In “The Enduring Fantasy of ‘Feeding the World’,” a recent article in the journal Spectre, four members of the Agroecology Research-Action Collective challenge those who make this claim. Join host Ronnie Lipschutz for a conversation about feeding the world with Dr. Adam Calo, Assistant Professor in the Geography, Planning and Environment group at Radboud University in the Netherlands, and Dr. Maywa Montenegro, Associate Professor of Agroecology and Critical Technology Studies in the UCSC Environmental Studies Department.

In October 2020, Governor Newsom issued Executive Order N-82-20 which establishes a state goal of conserving 30% of California’s lands and coastal waters by 2030 – known as 30x30. The 30x30 goal is intended to help accelerate conservation of our lands and coastal waters through voluntary, collaborative action with partners across the state. Five years later, how well has 30X30 met its goals? Join host Ronnie Lipschutz for a conversation about 30X30 with Meghan Hertel, Deputy Secretary for Biodiversity and Habitat at the California Natural Resources Agency, who recently drafted and published the 2025 annual progress report on 30x30, in coordination with the Governor’s Office.

Who knew there was a desert in the San Joaquin Valley inhabited by the “valley dragon,” aka, the “blunt-nosed leopard lizard.” The lizards have disappeared from 85% of their historical range as a result of agriculture, rural and urban development and pesticides, and are now threatened in what remains of the San Joaquin Desert. The Fresno Chaffee Zoo is raising leopard lizards and releasing them back into the wild, equipped with radio telemetry backpacks. Join host Ronnie Lipschutz on Sunday, August 31st for a conversation about the desert and the lizards, with guests Dr. Rory Telemeco, Research Director at the Fresno Chaffee Zoo, and Dr. Michael Westphal, from the Bureau of Land Management.

The United States has indicated that it will begin to explore commercial mining of mineral nodules on the international seabed, in violation of the UN Conference on the Law of the Sea and the International Seabed Authority. These nodules contain a variety of minerals used in cell phones, electric cars and other high-tech devices and could reduce U.S. reliance on questionable sources of rare earth and other metals. Opponents counter that the ecological damage imposed by such mining would far outweigh any benefits.But there is another argument for letting sleeping nodules lie: deep-sea mining is a multi-billion-dollar solution to problems that do not exist. Join host Ronnie Lipschutz for a discussion with Professors D.G. Webster of Dartmouth College and Susan Park, from the University of Sydney. They, along with several colleagues, recently published “The false promise of deep-sea mining,” a critique of the proposal focused on terrestrial mineral availability, limited social benefits and supply chain economics.

Everyone is angry with California’s private utilities. Rates keep rising, the utilities lack accountability and they are running roughshod over small-scale renewable energy. Why make your customers so mad? Is that anger justified? And what are the utilities planning for the future? Join SN! host Ronnie Lipschutz for a conversation with Loretta Lynch. Lynch was President of the California Public Utilities Commission from 2000 through 2002 and continued as a CPUC Commissioner until January 2005. Since then, she has been a strident advocate for the protection of ratepayers and against corruption in the utility industry, a role in which she continues today.

Food insecurity and food apartheid are a common challenge in many low-income and minority neighborhoods across the United States. Big supermarket companies avoid those areas because stores are unprofitable and small stores find that they make the most money on junk foods, sodas and liquor. Saba Grocers is an Oakland-based organization, founded in 2019, that works with those small stores to enable them to sell fresh produce sourced from minority farmers across the region. Join host Ronnie Lipschutz for a conversation with Lina Ghanem, director and co-founder of the Saba Grocers Initiative in Oakland.Here is another podcast of interest: Staff of Life is a locally-owned grocery store competing for consumer dollars in a market dominated by corporate giants. And so we ask: How does a local grocery store survive in a marketplace of corporate giants? The Food Chain Radio Show - Podcast with Michael Olson hosts Gary Bascou, Co-Founder of Staff of Life Natural Foods for a conversation about how a locally-owned grocery store can survive 56 years to be among the last to stand in a market dominated by corporate grocery giants. Topics include the culture that gave rise to “natural” and “organic” food markets; how those foods gave rise to Staff of Life Natural Foods Market; and how Staff of Life survives 56 years of competition with corporate food giants.
