Small as they may be, honeybees play a huge role in U.S. agriculture by pollinating plants that produce about a quarter of the food consumed by Americans, from apples and almonds to blueberries and beans.
Commercial beekeepers like Robert Harvey (pictured above) transport colonies of bees across the United States so they can carry out this vital work.

The roll of bees in farming is in trouble, however, as in recent years the animals have been dying at a rate the U.S. government says is economically unsustainable
Scientists, consumer groups and bee keepers say the devastating rate of bee deaths is due at least in part to the use of certain pesticides sold by agrichemical companies to boost yields of staple crops such as corn.
The companies have pointed to other factors, such as mites, as causes of bee deaths.
In attached audio, commercial beekeeper David Hackenberg (pictured above) talks about the issue.

The U.S. Department of Agriculture estimates total losses of managed honeybee colonies at 23 percent over the winter of 2013-14 – the latest in a series of annual declines.
The White House recently announced a plan to fund new honeybee habitats and to form a task force to study how to reverse the drop in honeybee populations.
