Researchers, farmers, beekeepers and others agree that the problem is related to a set of pesticides called neonicotinoids (or neonics). Studies show that neonics contribute to honey bee deaths, as well as to declines in native pollinators, birds and aquatic life. In addition to killing bees outright, research shows that even low levels of these toxic pesticides impair bees' ability to learn, find their way back to the hive, collect food, produce new queens and fight off illness. These science-based concerns are why The European Union has banned the most widely used neonics and the U.S. Fish and Wild Life Service will discontinue their use in wildlife refuges by 2016.
