From Sewage to Planet Savior?
The Power of Poop (start time: 5:41) This potent byproduct of our digestive system holds the promise of being a big part of the solution to several public health and environmental challenges of our time, such as drinking water scarcity and degraded cropland. In this week’s show, How On Earth’s Susan Moran interviews Dr. Bryn Nelson, a science writer and former microbiologist. His debut book, called Flush: The Remarkable Science of an Unlikely Treasure, recently appeared in paperback.

The Little Book of Aliens
In this Halloween episode, we talk with Dr. Adam Frank, an astrophysicst/astrobiologist at the University of Rochester, about his recent book: The Little Book of Aliens. We hear some of the stories and learn about the science of life “out there” – astrobiology – and the past, present, and future search for extraterrestrial intelligence.

Climate Change Maladaptations
Over the Seawall (start time: 7:33): One of the key things that makes us human is our ability to problem-solve. But often our engineered fixes backfire and even make the problem we’re trying to solve much worse. How On Earth host Susan Moran interviews journalist Stephen Robert Miller about how this applies to massive seawalls, re-engineered rivers, grandiose canals (such as the Central Arizona Project) and other technological fixes that have unintended consequences. Miller’s debut book, due out next week, is called Over the Seawall: Tsunamis, Cyclones, Drought, and the Delusion of Controlling Nature (Island Press). Check out Stephen’s upcoming book talks: Nov. 2 at CU Boulder’s ATLAS 102, 7:00-8:30 p.m.; and Nov. 28 at Boulder Book Store, 6:30 p.m.

Recovery: The Lost Art of Convalescence
In this episode of How on Earth we hear the full interview Beth did with physician and author Gavin Frances.
CU Kite Fall Flying Expo (starts 1:00) CU Boulder collaborates with NASA and the kite/toy store Into the Wind to share a Kite Flying Expo about how kites can be used for atmospheric science study.
RECOVERY: The Lost Art of Convalescence. (starts 8:05) Author Gavin Frances emphasizes the importance of taking an active role in one’s recovery and outlines many paths one can take in doing so. It is an act that we engage in and that has the potential to transform our lives, if only we can find ways to learn its rhythms and invest our time, energy, and participation.

Recovery: The Lost Art of Convalescence (excerpts) / Fund Drive
As part of the KGNU Fund Drive, this episode of How on Earth features excerpts of Beth Bennett’s interview of Dr. Gavin Francis about his book Recovery: The Lost Art of Convalescence. We explore the difference between sickness and health, and the gap between them: Recovery. Based on decades of treating disease and injury, Dr Francis proposes a more active role of the individual in their recovery. We also talk about the importance of self-care and compassion, the role of the environment we create for ourselves, and the importance of caregivers.

BirdCast Bird Migration Forecasting
BirdCast Migration Map
Fall bird migration is reaching its peak, with billions of birds traveling thousands of miles, mostly at night. We talk with Kyle Horton, director of Colorado State University’s AEROECO Lab, and a key member of BirdCast, which is a collaboration with the Cornell Lab of Ornithology. Kyle Horton shares the history of “weather radar” use in bird forecasting, plus refinements and algorithms, that fine tune the forecasts. We learn about BirdCast’s nationwide live migration maps, and bird migration forecasts for a city or a county, such as Boulder County Migration Forecasts. Additionally, we talk with AeroEcolab scientists Annika Abbott and Mikko Jimenez.
In the last 50 years, North American bird populations have dropped 30%. Light pollution draws many migrating birds to their death. The BirdCast Lights Out program encourages people and cities to turn out nonessential lights during key periods of bird migration in their areas.

Tackling Plastic Pollution
Plastics: From Pollution to Solutions (start time: 0:58) We all want to think that the yogurt tubs, takeout containers and other plastic products that we toss into our kitchen recycling bin will actually get recycled. Chances are, they won’t. Plastic product makers have for many years been deceptively applying the “chasing arrows” recycling symbol on their products, even when those products can not and will not be recycled. But some progress is being made in tackling the enormous plastics-pollution problem, including by forcing producers to truthfully label their plastic products, and passing legislation that holds companies financially responsible for the afterlife of their products. In this week’s show, host Susan Moran interviews Susan Shain, a reporting fellow at the New York Times who recently wrote an article about plastic recycling; and Jennifer Congdon, deputy director of Beyond Plastics, an environmental advocacy project based at Bennington College in Bennington, Vermont.

Artificial Intelligence for Police Body Cameras
AI for Police Worn Body Cameras (Starts 3:45) Body Cam AI uses artificial intelligence analysis for body cam transcripts. Can this new tech reduce excessive use of force and help restore public trust in policing? To learn more, we talk with Anthony Tassone, CEO of Truleo. Truleo is an AI system for analyzing body cam transcriptions. We also talk with City of Aurora Police Chief, Art Acedvdeo, who helped design this new tech, and is testing it out this year to evaluate its effectiveness in the field. And we talk with Anaya Robinson, Senior Policy Analyst for the ACLU of Colorado.

Road Ecology // Wildlife Crossings
Wildlife Crossings (start time: 0:58) In this week’s show, host Susan Moran interviews journalist Ben Goldfarb about his new book, Crossings: How Road Ecology is Shaping the Future of Our Planet. It’s hard imagine modern human society without roads, be they interstate highways or county dirt roads. Love them or hate them, roads make our lives convenient. But for wild animals trying to migrate or find a mate, vehicle traffic on roads spells death. (And of course it kills people and their pets as well.) Twenty-one species of wildlife face extinction due to roads. Vehicles kill one million animals every day in the U.S. alone. Goldfarb’s book explores both the causes of and creative solutions to habitat fragmentation and direct killings of wildlife by roads and car traffic.
