Oliver Milman joins the scientists tracking the decline of insect populations across the globe, including the soaring mountains of Mexico that host an epic, yet dwindling, migration of monarch butterflies; the verdant countryside of England that has been emptied of insect life; the gargantuan fields of U.S. agriculture that have proved a killing ground for bees; and an offbeat experiment in Denmark.

With urgency and great clarity, Milman explores this hidden emergency, arguing that its consequences could even rival climate change.

Join on us as we discuss The Insect Crisis, with acclaimed journalist Oliver Milman who dives into the torrent of recent evidence that suggests this kaleidoscopic group of creatures is suffering the greatest existential crisis in its remarkable 400-million-year history, on this installment of Leonard Lopate at Large on WBAI 99.5FM.
