"Honey bees have been suffering rapid population losses for over a decade now," Conyers said Tuesday. "Another decade of these mass die-offs will severely threaten our agricultural economy and food supply system.

"It is critical and extremely necessary that we immediately begin to examine the death of honey bees and quickly take action to secure our food supply system."
