All across the United States, honeybees are flying away from their hives and dying. Empty hives are causing a lot of worry about some important food crops.

 

Bees give us a lot more than delicious honey. They are pollinators—they enable plants to produce the fruits and nuts we enjoy by carrying pollen from one plant or flower to the next. The wind pollinates oats, corn, and wheat, but many other plants (like apple and cherry trees and melon vines) depend on insects, bats, and birds.
