In this episode we feature Dr. Bill Laurance of James Cook University in Cairns, Australia, talking about his team's work documenting the planetary infrastructure boom and the need for more positive, less 'doom and gloom' science communication, and then we welcome Dr. Michelle LaRue to the program. She is a research ecologist with the University of Minnesota's Department of Earth Sciences, and her current work is focused on using high-resolution satellite imagery to study the population dynamics of Weddell seals in Antarctica. You have to hear these seals' calls to believe them!
