66 million years ago an asteroid struck earth, causing the fifth mass extinction of species on earth. With the dinosaurs gone, new species proliferated all over the planet. Now we're in the sixth extinction––this time caused by people. But when did it start? And what happened on on this continent in particular? Dan Flores' new book, Wild New World: The Epic Story of Animals & People in America, explores the deep history of the North American continent, which was once populated by giant bison and mammoths, massive eagles and condors, ground sloths and dire wolves––all of whom were here when human beings first arrived tens of thousands of years ago––and how people affected their environment and its animals, from the first migrating bands to the wildly destructive European colonizers.

Brando Crespi has devoted decades to sustainable development as co-founder and Executive Chair at Pro Natura International and Global Biochar. His holistic approach to sustainable development could be called regenerative––instead of telling poor and exploited people what they should do, it's about recognizing and cultivating local leadership, helping them form a community vision for their future, providing the assistance necessary to achieve that vision, and then getting out of the way. Along the way, Crespi and his colleagues came across biochar, a substance made from burning bio waste (like sawdust and crop husks) and that has been used in the Amazon for millennia. As a soil amendment, biochar can bring dead soil back to life, improve crop yields, and decrease water use. It can also be used in industrial products and plastics. And its production can provide an energy source in communities looking to develop clean energy and regenerative agriculture.

John D. Liu started his career as a journalist and cameraman, covering politics, economics, and culture. In 1995, he began documenting the Loess Plateau in China, a massive landscape that had been destroyed by poor agriculture practices over the course of centuries. He watched and filmed as the landscape––and the people––came back to vibrant life over decades, through an intensive process that involved soil science, engineering, hydrological restoration, and the participation of local communities. The result was a living, lush, and sustainable ecosystem that produced more food with less land in agricultural production.

Gary Paul Nabhan, known by many as the "father of the local food movement," is a prolific author, scientist, and activist for a healthy and truly regenerative food system that respects the land and its plants and animals; the people grow food, process, and serve the food and their communities; and to all the rest of us who eat and want our food to nourish us. He's an ecumenical Franciscan brother whose service is devoted to food equity and justice. W.K., Kellogg endowed chair for food and water security at the University of Arizona, he’s the author of many books; his latest is Jesus for Farmers and Fishers: Justice for All Those Marginalized in Our Food System. He’s an agrarian and ethnobotanist and is winner of numerous accolades, including a MacArthur fellowship and many literary, environmental, food, and arts awards.

Coley Burgess grew up on a conventional farm, then studied mathematics and electrical engineering...and he brought his scientific rigor and curiosity to a 20-acre pecan farm that he and his family bought in southern New Mexico. The ground was bare and turned to mud––and then cracked, dry earth––after he irrigated. But a series of happy accidents, including the purchase of a milk cow for his daughter's digestive health, led to his growing grass and cover crops and eventually letting go of herbicides, pesticides, and even chemical fertilizers. 

Professor Phillip Warsaw's work is all about the interconnectedness of the systems that keep our lives going––food, housing, transportation, health care. In his research in Milwaukee  he discovered that in Black and Latino neighborhoods housing was significantly more expensive if it was near grocery stores, but the same wasn't true in more affluent White neighborhoods. Why? And does this mean that better food access leads to gentrification?

If you're a small or mid-size farmer, it's nearly impossible to compete against giant food conglomerates. But fairer policy could help smaller farms to prosper, provide healthy food and thriving communities, and keep more profits for food producers––rather than executives and stockholders. Sarah Carden is a policy advocate with Farm Action, a group working to democratize the food system in the U.S. She's also a vegetable farmer, who knows first hand what the barriers are for small and mid-size growers who are forced to compete against giant corporations. She talks about the movement for a more fair and regenerative Farm Bill in 2023––and beyond.  

Both big ag and small family farms have their problems...but what's the alternative? We talk with agricultural journalist Sarah Mock about the some possible models.

Linda and Larry Faillace spent years at the University of Nottingham in England, where Linda became an expert in Mad Cow Disease (BSE). Upon return to the U.S., they imported sheep from Europe, with USDA approval, and began a cheese making business in Vermont, with their three children active participants in the enterprise. But a few years later, the USDA came after them, claiming that their sheep might carry BSE, and told them to surrender their sheep. Because they had science on their side––no sheep had ever had BSE––the Faillaces fought back...with grim and dramatic consequences. Linda's book, Mad Sheep: The True Story Behind the USDA's War on a Family Farm , tells the story...well, most of it. The real reason for the USDA's attack on their farm was revealed a decade later, as she recounts in today's podcast. Still, Linda Faillace remains an optimist, and she and her husband have continued to make cheese and teach cheese making and culinary arts. She has a lot to say about the growing power of the ever-growing local food movement.

Congresswoman Teresa Leger Fernandez (D-NM-3), a native of Las Vegas, NM, deeply understands the challenges and strengths of rural people in northern New Mexico. She's been working to bring money to those whose property and livelihoods have been damaged by the recent wildfires and floods, and to build resilience––heathy soil and water practices––to provide more fire, flood, and drought resistance in the future. But getting federal money, and then distributing it to those who need it, is not an easy task. We discuss the needs, the daunting bureaucracies, and the short and longer term goals for restoring land and protecting communities.
