New Global Warming Novel

FLORA LICHTMAN, HOST:

Here's a big, giant question for you: Why do we believe what we believe? And how is it that two people can look at the exact same set of circumstances and see two completely different things? That philosophical question is at the center of a new book where, to put it another way, one person's beautiful miracle is another person's ecological crisis.

Here to talk more about that miracle - or crisis, depending on your point of view - is the writer Barbara Kingsolver. Her previous books include "Animal, Vegetable, Miracle" and "The Poisonwood Bible." She's been awarded the National Humanities Medal. Her new book is "Flight Behavior." It's a novel.
