The Case of the Vanishing Honeybees

In the past decade, the US honeybee population has been decreasing at an alarming and unprecedented rate. While this is obviously bad news for honeypots everywhere, bees also help feed us in a bigger way -- by pollinating our nation's crops. Emma Bryce investigates potential causes for this widespread colony collapse disorder.
