過去十年來，美國蜜蜂已減少到要拉緊報，且前所未有的數量了。這個問題對各地的蜂蜜罐來說顯然是個壞消息，但是蜜峰也在另一方面幫了我們大忙──為全國穀物授粉。艾瑪．布萊斯調查了這個普遍存在的「蜂群衰竭失調」問題發生的潛在因素。

The sudden and widespread decline of US honeybee populations reveals a crisis with consequences far beyond higher honey prices. In 2006, over half of all American hives were affected by colony collapse disorder, leaving hives eerily empty but full of untouched food and unhatched larvae. With bees responsible for pollinating more than one-third of America's crops, their disappearance jeopardizes food production and drives up costs. Multiple culprits, including parasites, pesticides, and genetic weaknesses, are likely behind this environmental mystery.
