Much of what we eat has been produced at some point with the help of bees. The lettuce and tomato in your hamburger were probably pollinated by bees and the cow that contributed to your beef patty was very likely fed on the hulls of almonds, which were also pollinated by bees. Our reliance on bees for our food production is endangered by a strange phenomenon that is killing off bees in droves: colony collapse disorder. Take this quiz to learn more about the bee crisis.
