Bees have been mysteriously disappearing since about 2006, in a phenomenon called Colony Collapse Disorder. They vanish from the hive leaving behind just the queen and the honey. Scientists don't have a clear explanation, but they theorize that pesticides and mechanized agriculture are to blame. That, essentially, we are killing the bees. A documentary out today called Queen of the Sun explores the disappearance of bees. Madeleine spoke to the director of the film, Taggert Siegel. And Kirk Anderson from Backwards Beekeepers is on hand with tips for people interested in keeping their own honeybees.
