Over thirty percent of our agricultural crops depend on bees for pollination -- including apples, cucumbers, melons, blueberries, and almonds. Bee pollination means about $15 billion in agricultural production for the United States. But these creatures, critical to ensure our food supply, are quickly disappearing. In the last 60 years, the number of bee colonies fell by 45%. In 2006, US beekeepers noticed massive bee die offs - something they've never seen before. Every year since 2006, one third of bee colonies in the United States disappear. This mysterious bee die off came to be called "colony collapse disorder." Colorado beekeeper Tom Theobald explains what's behind bee disappearance and what we need to do about it.
