Portland Bans Insecticide in Light of Massive Bee Deaths

Portland, Oregon has joined at least seven other cities in banning the usage of neonicotinoids, a class of insecticides that many scientists think is behind colony collapse disorder and the premature death and dysfunction of many bees and other pollinating insects. The ban applies to all city lands and will be enforced despite the opposition of some nearby farmers who claim neonicotinoids are critical for producing their food crops.
