Bob Simon's wild kingdom

From wars to famines, from the Olympics to overthrown dictators, Bob Simon has covered just about every major international event in his 44-year career at CBS News. (He won a Lifetime Achievement Emmy eight years ago, and he's still going strong.)

From time to time, Bob turns his attention away from getting shot at to give voice to endangered animals. He'll be the first to tell you, these stories are as compelling and important as any he has ever told.
