Much of America's crops could be in trouble.

FOX's Jill Nado reports:

Crops in California's Central Valley, the Midwest's corn belt and the Mississippi River Valley may be destabilized due to the massive die off of... bees.

A new study from the University of Vermont shows crops like cotton, soybeans, and apples are in danger because the missing bees in those regions mean less crop pollination.

The University's developed the first ever map of the counties hit hardest by the die off. And they estimate the number of bees in the wild has dropped 23% between 2008 and 2013.
