Not just honeybees have been dying. So have bumblebees.
The planet’s honey bee population has dropped precipitously over the past decade, and nobody is entirely sure why (though we have a sneaking suspicion that Bayer’s bee-toxic pesticides have something to do with it). It’s bad news for the one-third of American agriculture that relies on bee pollination. And it gets worse: this week, the Proceedings of the National Academy of Sciences (PNAS) published a study claiming that the population of four bumblebee species has dropped by up to 90 percent in the U.S. over the past 20 years.
