Over the past four centuries, the transformation of the Greater San Francisco Bay Region has been extraordinary.  What was once a near paradise for a few hundred thousand indigenous First Peoples is now home to nearly 8 million whose accumulated activities since the arrival of Europeans have created an industrialized landscape interspersed with large areas of open space where nature is in recovery...

Who knew that ponds make music ?  To the eye and ears, they seem silent and tranquil—except at night when, maybe, choruses of frogs serenade listeners.  But ponds are much noisier than that: you have to be very quiet and have the right equipment to really hear what’s going on.  And there is a lot going on: both the critters and the plants speak out.  Indeed, nature is full of sounds, many of them...

Everyone talks about climate but no one does anything about it.  In recent months, parts of Maui were nearly washed away by Kona Lows that dropped 60 inches of rain.  An unusual trio of Pacific cyclones on both sides of the equator drove warm oceanic water to the east, adding to climate turbulence.  And the world is being warned of an “off-the-charts” El Niño this coming fall and winter. And there...

The attack on Iran by the United States and Israel demonstrated, among other things, the necessity of a rapid transition to renewable fuels, like solar and wind.  The technologies for capturing and converting them into usable form are heavily dependent on critical minerals, such as lithium, cobalt and others. Indeed, critical minerals are driving a new wave of resource nationalism and extraction a...

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 wh...

We’ve heard a lot about the problem of microplastics pollution. Just how bad is it?  What are its causes?  What are microplastics doing to us and the world?  Is anything being done to stem the accelerating production and consumption of plastics that end up in our water, our air, in animals, and in human bodies? Liste to a conversation about microplastics with host Ronnie Lipschutz, Dr. Myra Finkel...

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 projec...

The State of California has created a program called “Transformative Climate Communities,” focused on making low-income, urban areas more resilient, efficient and responsive to housing, energy and climate challenges. What does this mean on the ground? Join host Ronnie Lipschutz for a conversation with Nancy Faulstitch , Executive Director and Eloy Ortiz , Special Projects Manager at Regeneración P...

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, Cal...

Over the past several decades, there has been a concerted effort by biologists, economists and others to put a value on nature’s services : what would it cost, for example, to provide clean water the way nature does?  Oxygen, photosynthesis, soil?  Early estimates were around $30 trillion per year; arguably, today they are much higher, over $100 trillion.  But getting from hypothetical calculation...

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...

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 nuclea...

Many listeners are probably familiar with the tags found in hotel bathrooms that read: “Save Our Planet,” followed by instructions about reusing and replacing towels, and concluding “Thank you for helping us converse the Earth’s vital resources.”  Reusing towels might help conserve the hotel’s financial resources but does that make any difference for the Planet?  Such “lifestyle environmentalism”...

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, anim...

The Kenneth S. Norris Center at UC Santa Cruz is one of the little-known jewels of the campus as well as the Monterey Bay Region. Ken Norris was an American marine mammal biologist , conservationist, naturalist, and co-founder of SeaWorld , as well as a professor of natural history at UCSC.  He was the creator of the UC Natural Reserve System , too.  The Norris Center holds a vast collection of in...

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 pho...

Millions of Americans see themselves as "conflicted omnivores," worrying about the ethical and environmental implications of their choice to eat animals. Yet their attempts to justify their choices only obscure the truth of the matter. Join host Ronnie Lipschutz for a conversation with Dr. John Sabonmatsu , Professor of Philosophy at Worcester Polytechnic Institute in Massachusetts.  His...

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...

Tom Lehrer, the musical satirist par excellence of the 1950s and 1960s, died this past July at age 97.  Many listeners and their progeny grew up listening to and singing his compelling compositions: easy to remember, easy to sing and easy to finish.  Who could forget “The Vatican Rag” or “The Elements?” What some might not know is that, from 1972 to 2001, in flight from East Coast winters, Tom als...

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...

What’s up with climate change and climate law?  The U.S. Environmental Protection Agency has announced that it is going to cancel the “endangerment finding” of 2009 that provided the legal basis for regulation of greenhouse gas emissions. In July, the Department of Energy released “A Critical Review of Impacts of Greenhouse Gas Emissions on the U.S. Climate,” which downplayed the research, the imp...

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 th...

The world is awash in plastic. According to a study published in 2020, total production of plastics since 1950 is now over 10 billion tons, with more than half of that simply discarded.  And the production of plastics will only increase in the future.  There is a lot of oil and natural gas in the world and, if and when we wean ourselves from fossil fuels, oil and chemical companies will be looking...

As the recent deadly floods in Central Texas remind us, Nature bats last.  There seem to be a growing number of severe weather-related disasters that kill many people and lay waste to towns and communities.  But what happens after the floods, as communities make plans to repair the damages?  Why does rebuilding often become the trigger of intense and extended political and social struggle, sometim...

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...
