The pollination of crops by bees is responsible for a third of the food produced in the US.
One in every three mouthfuls has been touched by their tiny feet; but our six-legged friends are in trouble.
They are getting sick and leaving their hives. Without bees, food gets more expensive - some products could disappear altogether.
Colony collapse disorder (CCD) emerged in 2006, and by spring 2007 bees were dying in huge numbers - over the year as a whole the total bee population fell by 30%.
