Today: border critters and beaked whales. Two stories about human actions disrupting the ecosystems and lives of other animals with whom we share the planet. First, a tale of how the U.S. Navy’s sonar activities created an acoustic storm in the Great Bahama Canyon, impacting a population of remarkable, rare whales. Second, we brush the dust off a once-forgotten research paper about the likely ecological impacts of a coast-to-coast U.S.-Mexico border wall. Featuring student producers Denley Delaney and Maddy Belin; sound design by Jackson Roach. Image credit: Blainville's Beaked Whale, by MatthewGrammatico. Season 9, Episode 2.
