    Dear Friend, Since 2006, U.S. honey bee populations have been in precipitous decline, with some estimates suggesting losses as high as 30% per year. While that's terrible, the problem is far greater than just the loss of a species. Without bees, our food supply is in serious danger. Pollination...
