Burt Knows Bees

Colony Collapse Disorder (or CCD) is a phenomenon in which worker bees from a beehive or Western honey bee colony abruptly disappear. While such disappearances have occurred throughout the history of apiculture, the term Colony Collapse Disorder was first applied to a drastic rise in the number of disappearances of Western honey bee colonies in North America in late 2006. (via Wikipedia).

Burt's Bees is dedicated to researching this issue, and saving the honey bees. Have a look at this view they created.
