Tracking The Hidden Dangers Of Fighting Fires

Firefighting is a career with an inherent cancer risk, but a full understanding of what those risks are has been elusive. An important registry designed to help understand the link between firefighters and cancer was taken offline on April 1 because of federal cuts, then restored six weeks later. Host Flora Lichtman discusses this with firefighter health researcher Sara Jahnke and reporter Murphy Woodhouse from Boise State Public Radio and the Mountain West News Bureau.

Plus, pests and pathogens are ravaging keystone tree species in forests across the country. Flora discusses the innovative science behind breeding pest-resistant trees with Leigh Greenwood from The Nature Conservancy.
