A new documentary seeks to unravel the mystery of why billions of honey bees have been disappearing from hives across the United States.
"Vanishing of the Bees" follows a group of U.S. beekeepers hit by Colony Collapse Disorder (CCD), which first struck in 2004 and made U.S. headlines three years later.
Countless bees would suddenly vanish, leaving an empty hive but few bodies. While the cause has yet to be established, the film suggests there is a link to Bayer’s "Gaucho" insecticide.
