Voir Dan Rather Reports, Season 8 - Episode 10

(4/2/2013) We’ve reported extensively about the mysterious disappearance of honeybees. Scientists have been unable to pinpoint the exact cause, but the little insect that’s responsible for pollinating one third of everything we eat is dying….quickly. And some of the biggest commercial beekeepers are now saying the unthinkable – that their industry may be on the brink of extinction…with some unable to rebuild after 50 to 90 percent losses this year. Also, an important investigation from the slums of Karachi. The dangerous downside of one of our greatest intelligence coups -- finding Osama bin Laden -- is creating major roadblocks for eradicating polio from Pakistan.
