The world honey bee population has plunged in recent years, worrying beekeepers and farmers who know how critical bee pollination is for many crops. A number of theories have popped up as to why the North American honey bee population has declined–electromagnetic radiation, malnutrition, and climate change have all been pinpointed. Now a leaked EPA document reveals that the agency allowed the widespread use of a bee-toxic pesticide, despite warnings from EPA scientists.
The document, which was leaked to a Colorado beekeeper, shows that the EPA has ignored warnings about the use of clothianidin, a pesticide produced by Bayer that mainly is used to pre-treat corn seeds. The pesticide scooped up $262 million in sales in 2009 by farmers, who also use the substance on canola, soy, sugar beets, sunflowers, and wheat, according to Grist.
