U.S. honeybees continue to die at a rate of 30% a year. If the problem isn't solved, it's going to make food more expensive. Ramesh Sagili, a bee expert at Oregon State University, says there isn't one problem. Mites are killing some bees, others are dying because of a bad diet and genetically bees are not diverse. Beekeepers are keeping populations alive by taking new queens and splitting hives, but that's a slow process. Finding a solution to mites and improving the genetic pool also take years. It is likely that the shortage of bees will continue to cause food prices to rise.
