Geologist David Montgomery and biologist Anne Biklé, authors of the influential "Dirt Trilogy" (Dirt: The Erosion of Civilizations; The Hidden Half of Nature; and Growing A Revolution: Bringing Our Soil Back to Life), preview their forthcoming book, "You Are What Your Food Ate." They present scientific evidence demonstrating how soil health profoundly impacts the health of crops, animals, and ultimately humans. Their work highlights the critical link between soil life and food's nutritional quality, emphasizing that regenerative farming practices benefit both the land and human health.

This talk was delivered at the 2021 Bioneers Conference.

Host Jeff Corwin celebrates the Endangered Species Act (ESA), landmark 1973 legislation protecting vulnerable wildlife and ecosystems. The bald eagle, once near extinction, exemplifies the ESA's success, having recovered and now thriving across the U.S.

The ESA also protects sea turtles, with Florida's beaches being globally vital nesting sites. Conservation efforts, like Boca Raton's beachfront parks, are crucial. While only 1 in 10,000 hatchlings survive to adulthood, protecting their habitat allows these keystone species to flourish. All six sea turtle species nesting in America are protected by the ESA.

David Keith reviews the science and technology of solar geoengineering, examining its potential to reduce climate risks, associated new risks, and current uncertainties. He proposes integrating solar geoengineering into a comprehensive 4D climate policy, which includes emissions cuts, carbon removal, and adaptation.

A distinguished expert, David Keith is a Harvard Professor of Applied Physics and Public Policy. He founded Carbon Engineering, a company developing technology to capture CO2 for carbon-neutral fuels. Best known for his work on solar geoengineering, he led Harvard's Solar Geoengineering Research Program. He has authored over 200 academic publications and "A Case for Climate Engineering."

The session was moderated by Greg Bronevetsky.
