Bee Killer

Neonicotinoids, A class of pesticides, is extremely dangerous to bees and threatens crops that depend on pollination by bees. The pesticide kills brain cells of bees, hindering their ability to learn, collect food or reproduce. In a study, bees were fed a sugar solution with very low levels of neonicotinoid (2.5 parts per billion), found typically in flowers, and the movements of the toxins to the brain was tracked. It emerged that even one-tenth of these levels were enough to harm bees.
