Ep. 103 Toxic Air in Our Homes
After Hurricane Katrina devastated the Gulf Coast, a slow moving public health disaster followed in the form of disaster recovery: the ubiquitous FEMA trailers that were quickly utilized by rebuilding families turned out to often have extremely high levels of formaldehyde in them. Dr. Nicholas Shapiro (UCLA) spent years following these trailers to understand the impacts of living in toxic environments. His new book, Homesick, offers lessons not only in disaster recovery but for how we continue to build homes (especially amid a housing crisis) and the risks of running to the fastest, cheapest solutions. Across our conversation we discuss ways to improve indoor air quality, as well as discuss how we can ensure healthy homes going forward as we continue to meet the rising demand for houses across the country.

Ep. 101 Can We Make It Rain?
Drought is increasing around the world, and with it desperate conditions for farmers and rural communities. Water shortages present major economic and political threats in the coming decades. One potential solution, much speculated on but less evidenced, is the controversial practice known as "cloud-seeding." Today we sit down with scientists and entrepreneurs to discuss how this practice is being deployed, what its effects are, and what its future might be.
-

Ep. 100 The Mineral Challenge to Electrification
Scientists agree that more electricity will be needed to power the world, and that we should use more renewable energy to meet that demand. But electrifying our world takes more minerals to build that infrastructure, especially lithium. How can industry keep up, and what are the risks and challenges in building out new mining facilities around the world? We sit down with Thea Riofrancos (Providence College) to discuss her new book, Extraction: The Frontiers of Green Capitalism, all about these challenges.

Ep. 99 How Urban Park Revitalization Took Over
Ever since the development of the High Line in New York, urban leaders have recognized the potential for unconventional spaces -- especially in economically marginalized areas or in deindustrialized spaces -- for new greenways. These spaces are often privately led, and explicitly aim for economic development as a goal of the new amenity. We sit down with Kevin Loughran (Temple University) to talk about his book, Parks for Profit, and the development of urban parks across the country, including Buffalo Bayou Park in Houston.

Teaching the science of ecology and environment is an essential part of educating the next generation of environmental caregivers. But how we communicate those core ideas and help future scientists to understand the world around us requires finding ways of connecting and learning across science and nature. Artist Boat, a local nonprofit dedicated to science education through the arts, works to bridge that divide through artistic engagement and conservation work. On today's show we talk to their Karla Klay, their executive director, to learn all about how they marry art and science to help protect our environment.
