Scientists believe the asteroid that caused the fifth extinction killed off the dinosaurs. This time we're the asteroid; the sixth is being caused by human behavior. Elizabeth Kolbert talks about her book, The Sixth Extinction – which is a finalist for the Book Critics Circle Award in nonfiction and is out in paperback. Kolbert says amphibians are the world’s most endangered class of animals. Also heading toward extinction are “a quarter of all mammals, a fifth of all reptiles and a sixth of all birds.”
Also rock historian Ed Ward tells us about Cosimo Recording Studios – New Orleans’ only studio in the ‘60s. It made great records by Aaron Neville, Johnny Adams, Robert Parker and others.
