A freighter ran aground in the middle of the South Atlantic and is leaking oil on a remote place where many rare birds live. Marine biologist David Guggenheim was aboard a luxury eco-tourist ship when they got the mayday call from the sinking ship. Guggenheim tells host Bruce Gellerman about the harrowing rescue at sea and how even a small amount of oil spilled in a remote part of the world can have a devastating impact on wildlife.
