在上个年代，美国的蜜蜂数量以一个前所未有的惊人的速度减少。虽然这显然对任何地方的蜜罐都是一件坏事，但与此同时蜜蜂也正在通过一种更强大的方式为我们提供食物--对全国的农作物授粉。艾玛·布莱斯调查了大范围发生的蜂群崩坏综合症的潜在原因。

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.
