Sustainability Now! on KSQD.org ·

2026/03/01

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 calculations to actual incorporation into real work policy and

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

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 musical and, quite possible, the forerunners of human

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

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?

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.

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.

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 also taught math and theater at UC Santa Cruz, as a lecturer

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
