Science journalist Elizabeth Kolbert has watched an invasive species of Asian carp jump 10 feet into the air when they’re shocked. She’s gone to the Mojave Desert to see how researchers are trying to save tiny little pupfish. And she’s traveled to the Great Barrier Reef to see coral that’s turned as white as a ghost because of rising water temperatures. Kolbert talks about far-out environmental fixes and what’s in store for our children on Planet Earth. “Now What?” is produced with the help of Steve Zimmer, Tay Glass and Alex Wolfe. Audio production is by Nick Ciavatta.
