Honeybees are in a crisis. Every year we lose about a third of these endangered creatures, which we rely on to pollinate most of the world's daily food. But as farmers face devastating losses, scientists are finding hope in the huge and barely tapped world of the 20,000 species of wild bees. These are the innovative methods and unusual experiments biologists are working on in their race to end this global calamity. 蜜蜂正处于危机之中。每年我们都会失去大约三分之一的这些濒危生物，我们依靠它们来为世界上大多数日常食物授粉。但是，当农民面临毁灭性的损失时，科学家们在20，000种野生蜜蜂这个巨大且几乎未被开发的世界中找到了希望。这些都是创新的方法和不寻常的实验，生物学家正在为结束这场全球灾难而努力。
