175. David Haskell with Lyanda Lynn Haupt: The Evolution of Sound
Our world constantly vibrates with sound, from the delicate flap of an insect’s wings to the thunderous roar of a rocket launching into space. There’s the spring chorus of frogs. The sputter of a creek and the whoosh of a sudden breeze. Songs, music, and speech. But the sounds of today aren’t necessarily the same sounds that our ancestors encountered. How have sounds changed? What might be missing from our present and future sonic experiences? In his new book, Sounds Wild and Broken, biology professor David Haskell explored how the wonders of sound came to be on a journey through our planet’s history. Tracing a sonic path from animal song to modern concert halls, he illuminated how sounds emerged and evolved alongside all of Earth’s living things. But despite the explosive creation of sounds over time, Haskell pointed out that there is also erasure; threats to sonic diversity impact our forests, oceans, and experiences as human beings. Haskell considered how the loss of sounds can make the world less creative, just, and beautiful, prompting the question: How can reverence for sound help guide us in a rapidly-changing world? David Haskell is a professor of biology and environmental studies at the University of the South and a Guggenheim Fellow. His work integrates scientific, literary, and contemplative studies of the natural world. He is the author of The Songs of Trees (2017), which won the John Burroughs Medal for Outstanding Nature Writing. His first book, The Forest Unseen (2012), was a finalist for the Pulitzer Prize and the PEN/E.O. Wilson Literary Science Writing Award, and was honored with the 2013 Best Book Award from the National Academies, the National Outdoor Book Award, and the Reed Environmental Writing Award. You can listen to a collection of sounds from his most recent book, Sounds Wild and Broken, here. Lyanda Lynn Haupt is an award-winning author, naturalist, ecophilosopher, and speaker whose writing is at the forefront of the movement to connect people with nature and wildness in their everyday lives.

174. Charlotte Coté with Dana Arviso: Stories of Indigenous Food Sovereignty from the NW
In the dense rainforest of the west coast of Vancouver Island, the Somass River (c̓uumaʕas) brings sockeye salmon (miʕaat) into the Nuu-chah-nulth community of Tseshaht. C̓uumaʕas and miʕaat are central to the sacred food practices that have been a crucial part of the Indigenous community’s efforts to enact food sovereignty, decolonize their diet, and preserve their ancestral knowledge. In A Drum in One Hand, a Sockeye in the Other, Charlotte Coté shared contemporary Nuu-chah-nulth practices of traditional food revitalization in the context of broader efforts to re-Indigenize contemporary diets on the Northwest Coast. Coté offered evocative stories — rooted in her Tseshaht community and in her own work — to revitalize relationships to haʔum (traditional food) as a way to nurture health and wellness. As Indigenous peoples continue to face food insecurity due to ongoing inequality, environmental degradation, and the Westernization of traditional diets, Coté foregrounded healing and cultural sustenance via everyday enactments of food sovereignty: berry picking, salmon fishing, and building a community garden on reclaimed residential school grounds. Charlotte Coté (Tseshaht/Nuu-chah-nulth) is Associate Professor of American Indian Studies at the University of Washington, and has been teaching in AIS since 2001. Dr. Coté holds a Ph.D. and M.A. in Comparative Ethnic Studies from the University of California at Berkeley and is Affiliated Faculty in the UW’s Jackson School Canadian Studies Center.

173. Vidya Krishnan with Amber Payne: The Past, Present, and Future of Tuberculosis
Tuberculosis might seem like a disease of the past in the West, but globally it remains a persistent and costly threat across all age groups. According to the World Health Organization, over 1.5 million people died from TB in 2020 — could it be on track to re-emerge as the next global public health crisis? According to medical science journalist Vidya Krishnan, the disease could be mounting a “frightening comeback.” In her new book, Phantom Plague, Krishnan traced a century of TB’s history from the slums of 19th-century New York to modern Mumbai. She described how superstition and folk remedies made way for scientific understanding of TB, leading to its high rate of control and cure in the West. But, she argued, the cure was never available to Black and Brown nations. As recent as 2020, just eight countries accounted for two-thirds of new TB cases, with India leading the count, followed by China, Indonesia, the Philippines, Pakistan, Nigeria, Bangladesh, and South Africa. Through a social history of the disease and the stories of doctors and patients who have battled it, Krishnan painted a picture of urgency as weak links are exposed, and new drug-resistant strains of TB are becoming dominant. Vidya Krishnan is an award-winning journalist who has been reporting on medical science for the last 20 years. She has written for The Atlantic, The L.A. Times, The Hindu (as their health and science editor), and for the British Medical Journal. Amber Payne is co-editor in chief of The Emancipator at Boston Globe Media. She was a 2021 Nieman fellow at Harvard University, and formerly served as managing editor of BET.com and as executive producer of Teen Vogue and Them.

172. Matt Richtel: The New Science of the Immune System
The human immune system is nothing short of remarkable: it helps our bodies ward off bacteria and viruses, heals wounds, and maintains the balance needed to keep us alive. The good news? Our immune systems are no longer threatened by the plagues and common diseases of the past. The bad news? Our bodies face an array of distinctively modern challenges; threats like fatigue, stress, and exposure to toxins, which place undue pressure on a system that typically keeps us healthy. Could the results of such stressors be weakened immunity and an explosion of autoimmune disorders? In his new book, An Elegant Defense, bestselling author Matt Richtel explored this very question through the stories of four people — a cancer patient, an HIV patient, and two women with autoimmune diseases. Combining these human accounts with anecdotes, insight from leading researchers, and the latest scientific findings, Richtel described how the body’s forces unite to ward off bacteria, parasites, and tumors. And on the flip side, he explained how sometimes the body’s defenses can become a threat and attack organs and other systems. Richtel investigated why: Is there a close connection between mental health and the immune system? What roles do diet and nutrition play in immunity? What might be weakening our immune systems? (Think antibacterial soaps, immune boosters, and other products marketed to “protect” us.) With discussion about health and the immune system remaining in the spotlight as the COVID-19 pandemic rages onward, Richtel offered a particularly relevant look into the deepest riddles of human survival and suggests potential keys to improving wellness. Matt Richtel is a Pulitzer Prize-winning New York Times reporter and bestselling nonfiction and mystery author. He lives in San Francisco with his wife, Meredith, a neurologist, and their two children. In his spare time, he plays tennis and piano and writes (not very good) songs.

171. Dr. Carl L. Hart with Professor Jennifer Oliva: Drug Use for Grown-Ups
Is it possible for drug use to be part of a responsible, balanced, and happy life? Dr. Carl L. Hart, a prominent neuroscientist and professor of psychology at Columbia University, believes so; but he didn’t always see it that way. Dr. Hart grew up in Miami at a time when drugs like crack cocaine were blamed for his city’s problems. Initially, his research aimed to prove that drug use led to bad outcomes. But what he found was unexpected: the facts didn’t support the ideology, the truth was dismissed and distorted to keep fear and outrage stoked, and more Black and brown bodies ended up behind bars. In his new book, Drug Use for Grown-Ups, Dr. Hart asserted that responsible drug use does more to enrich lives than to harm them. Based on personal experience and decades of research, he argued that criminalization and demonization of drug use — not the drugs themselves — are what caused negative outcomes and reinforced structural racism in America. Dr. Hart was joined in conversation with Professor Jennifer Oliva for a timely reflection on America’s war on drugs, the unjust stigmas that persist, and how we might develop a new vision of drug use. Carl Hart is the Ziff Professor of Psychology in the Departments of Psychology and Psychiatry at Columbia University. He is also a Research Scientist at the New York State Psychiatric Institute. Dr. Hart has published numerous scientific and popular articles in the area of neuropsychopharmacology and is co-author of the textbook Drugs, Society and Human Behavior. His book High Price was the 2014 winner of the PEN/E.O. Wilson Literary Science Writing Award. Jennifer D. Oliva is the Associate Dean for Faculty Research & Development and director of the Center for Health & Pharmaceutical Law at Seton Hall Law, where she specializes in health law and policy, FDA law, privacy, evidence, and complex litigation. She also serves as a senior scholar with the O’Neill Institute for National & Global Health Law at Georgetown Law and on the National Pain Advocacy Center’s science and policy advisory council. Oliva is the recipient of multiple scholarly and professional awards and has served as a peer reviewer for numerous law and health journals. Her scholarship has been published by or is forthcoming in the California Law Review, Duke Law Journal, and many others.

170. Robin George Andrews: What Volcanic Eruptions Can Reveal About Our Planet
Volcanoes have long fascinated curious humans of all ages. Here in the Seattle area, our beloved Tahoma (Mount Rainier) and the four other active volcanoes in the Cascade Mountain Range are beautiful but ever-present reminders of Washington’s location in the “Ring of Fire,” a 25,000-mile arc of volcanic activity that follows the rim of the Pacific Ocean. Volcanoes are quite literally our neighbors; how can we get to know them better and understand their role in shaping and reshaping our planet? Is there a way to safely live alongside them? In his new book, Super Volcanoes, science journalist and volcanologist Robin George Andrews walked us through awe-inspiring eruptions of the past and present and the secrets that they reveal about our planet. We already know quite a bit about how volcanoes form, erupt, and change, but many mysteries and questions remain: Is Earth’s unique system of plate tectonics the best way to forge a planet capable of supporting life? How can we better predict eruptions and protect communities in the path of danger? Andrews took us from the ocean floor to Hawai’i, Yellowstone, Tanzania, and planets beyond ours to explore recent discoveries and lingering questions about the geologic wonders that captivate us. Robin George Andrews is a science journalist with a Ph.D. in volcanology. His writing has appeared in The New York Times, The Atlantic, National Geographic, Scientific American, Atlas Obscura, and other publications. He lives in London, England.

169. Howard Frumkin with Joseph Winters: A Roadmap for Protecting Nature to Protect Ourselves
It’s no secret that human health and the health of Earth’s systems — in particular, the air, water, biodiversity, and climate — are inextricably linked. It’s also no secret that Earth’s systems are changing in ways that can feel daunting and unwieldy. But with all great change comes great opportunity, and the emerging field of Planetary Health offers glimmers of hope rooted in actions, strategies, and a deepened understanding of our interconnectedness. In Planetary Health: Protecting Nature to Protect Ourselves, editor and University of Washington professor Howard Frumkin brought together a comprehensive collection of topics to guide our understanding of how a changing environment affects our health. With contributions by dozens of authors, the book covers a wide range of health impacts that include food and nutrition, infectious disease, non-communicable disease, mental health, and more. But the goal of the book isn’t to deliver a message of doom; it also offers optimistic strategies to combat the ill effects of environmental changes, such as controlling toxic exposures, investing in clean energy, and improving urban design, among others. Together, the two dichotomies illustrate how an interconnected approach to public health can benefit both people and the planet. In the Town Hall Forum, Frumkin talked about the field of Planetary Health, our changing environment, its impact on everyone from health professionals to students — and far beyond. Howard Frumkin is Professor Emeritus of Environmental and Occupational Health Sciences at the University of Washington School of Public Health in Seattle, where he was dean from 2000 through 2006. He was previously head of the Wellcome Trust “Our Planet, Our Health” initiative, and director of the National Center for Environmental Health at the US Centers for Disease Control and Prevention. He is also the author of Planetary Health: Safeguarding Human Health and the Environment in the Anthropocene. Joseph Winters is an early-career journalist covering climate as Grist’s News and Politics Fellow. He recently graduated from Harvard University, where he was involved in journalism and climate advocacy — including in his role as senior U.S. editor for the Harvard Political Review and as an organizer for Fossil Fuel Divest Harvard. He has previously interned at the Public Radio International show Living on Earth and at NPR’s Oregon Public Broadcasting.

168. Lynda V. Mapes: The Natural History of the Orca and the Threats to Their Survival
In July of 2018, Orca whale J35, also known as “Tahlequah,” gave birth to a calf off the coast of British Columbia. When the calf died shortly after birth, the world grieved alongside J35 as she carried the calf for 17 days across 1,000 miles before finally releasing it and rejoining her pod. Grief that transcends species is an extraordinary thing; it sparked a revival awareness of the critical need to preserve orcas, the chinook salmon they feed on, and their habitat — together, core elements of Pacific Northwest identity. In her book, Orca: Shared Waters, Shared Home, environmental journalist Lynda Mapes discussed one of the most urban whales in the world and why our efforts to protect them matter now, more than ever. The Southern Resident whales are a community of orcas that live in the Pacific waters spanning from Southeastern Alaska to central California. They are the only killer whale population listed under the U.S. Endangered Species Act; as of September 2021, only 73 Southern Resident Whales remain and they are threatened by habitat degradation, lack of chinook salmon (their primary food source), relentless growth, and climate change. Walking through Orca, which is co-published with The Seattle Times and features photographs by photographer Steve Ringman as well as from other partner organizations, Mapes explores the natural history of the orca and their unique challenges for survival. For more content about the orca, tune in to an interview with Lynda Mapes and Town Hall’s Fall 2021 Podcast Artist-in-Residence, Samantha Allen. Lynda V. Mapes is a journalist, author, and close observer of the natural world, and covers natural history, environmental topics, and issues related to Pacific Northwest indigenous cultures for The Seattle Times. She is the recipient of a 2014-2015 Charles Bullard Fellowship in Forest Research and is the author of Witness Tree.

167. Neal Stephenson: Termination Shock
Bestselling author Neal Stephenson is known for delivering novels with poignant and incisive reflections on our present and future. He’s also no stranger to the Town Hall stage and has joined us in the past to discuss his novel Fall and collaborative work with Nicole Galland, The Rise and Fall of D.O.D.O., among others. Stephenson returned to the Town Hall stage to discuss his newest thriller, Termination Shock. In his speculative vision of the not-too-distant future, sea levels are rising, heatwaves and global flooding endure, and deadly pandemics threaten humanity. When the rest of the world continues to respond with inaction, a billionaire hatches a plan that will quickly throw climate change into reverse — but action at such a grand scale is anything but simple. There are consequences of global proportion, and some of them might even be worse than climate change itself. Stephenson’s discussion invited audiences to consider questions that can extend far beyond fiction and resonate with us in the present day: Will the world ever be able to take urgent action on climate change? What is the role of technology in this fight? Is there a role for motivated billionaires? What if the answers to these questions are highly unconventional? Stephenson invited us to expand our minds, and ask. Neal Stephenson is the #1 New York Times bestselling author of the novels Fall; or, Dodge in Hell, Seveneves, Reamde, Anathem, The System of the World, The Confusion, Quicksilver, Cryptonomicon, The Diamond Age, Snow Crash, and Zodiac, and the groundbreaking nonfiction work In the Beginning . . . Was the Command Line. He is also the coauthor, with Nicole Galland, of The Rise and Fall of D.O.D.O. He lives in Seattle, Washington.

166. Hannah Zeavin with Dr. Margaret Morris and Dr. Orna Guralnik—The Distance Cure: A History of Teletherapy
When you think of therapy in a traditional sense, what comes to mind? Television shows, movies, and comics love to paint a stereotypical scene: a bespectacled therapist asks poignant questions and jots down notes on a legal pad; meanwhile, the patient reclines on a sofa and spills their thoughts and emotions into the void of the room. It might be easy to assume that therapy has always involved a person-to-person conversation, but in her new book The Distance Cure, scholar and author Hannah Zeavin invited us to consider definitions of psychotherapy that extend far beyond people talking in a room. In The Distance Cure, Zeavin described less conventional operations of therapy that include Freud’s treatments by mail, advice columns, radio shows, crisis hotlines, video, computers, and mobile phones. Across all formats, “therapists” vary widely in background and credentials; some may be professionally trained, while others are strangers or even chatbots. Is any method better than the other? Zeavin urged us to think beyond the traditional dyad of therapist and patient and consider the triad of therapist, patient, and communication technology. By tracing the history of teletherapy right up to its now-routine application in pandemic therapy sessions, Zeavin reminded us that as our world changes and advances in communication technology continue to expand, so will our definitions of what it means to connect. In a virtual presentation, Psychologist Margaret Morris interviewed Hannah Zeavin about her new book and the intimacy that is possible in remote communication. They are joined by Dr. Orna Guralnik, a clinical psychologist featured on Showtime’s Couples Therapy, who shared insights about therapy and connection during the pandemic. Hannah Zeavin is a Lecturer in the Departments of English and History at the University of California, Berkeley, and is affiliated with the University of California, Berkeley, Center for Science, Technology, Medicine, and Society. She is a Visiting Fellow at Columbia University’s Center for Social Difference and Editorial Associate at The Journal of the American Psychoanalytic Association. Her work has appeared or is forthcoming in American Imago, differences: A Journal of Feminist Cultural Studies, the Los Angeles Review of Books, Real Life Magazine, Slate, and elsewhere. Dr. Margaret Morris is a clinical psychologist focused on how technology can support wellbeing. She is an affiliate faculty member in the Information School at the University of Washington, as well as a research consultant. Morris is the author of Left to Our Own Devices: Outsmarting Smart Technology to Reclaim Our Relationships, Health and Focus. Dr. Orna Guralnik is a clinical psychologist and psychoanalyst practicing and teaching in New York City. Currently Dr. Guralnik lectures and publishes on the topics of couples treatment and culture, dissociation and depersonalization, and culture and psychoanalysis. She has completed the filming of several seasons of the Showtime documentary series, Couples Therapy.
