Einstein famously declared that were the bees to die, in four years we would die:
Newly published scientific evidence is bolstering calls for greater regulation of some of the world’s most widely used pesticides and genetically modified crops.
Earlier this year, three independent studies linked agricultural insecticides to colony collapse disorder, a phenomenon that leads honeybees to abandon their hives.
Beekeepers have reported alarming losses in their hives over the last six years. The USDA reports the loss in the United States was about 30 percent in the winter of 2010-2011.
Bees are crucial pollinators in the ecosystem. Their loss also impacts the estimated $15 billion worth of fruit and vegetable crops that are pollinated by bees in the United States.
The studies, conducted in the United States, France, and the United Kingdom, all pointed to neonicotinoids, a class of chemicals used widely in U.S. corn production, as likely contributors to colony collapse disorder. The findings challenged the EPA’s position—based on studies by Bayer CropScience, a major producer of the neonicotinoid clothianidin—that bees are only exposed to small, benign amounts of these insecticides.
The new studies found that bees are exposed to potentially lethal amounts of neonicotinoids in pollen and in dust churned up by farm equipment. They also found that exposure to neonicotinoids can reduce the number of queen bees and disorient worker bees.
