POPSLife Without Bumblebees? It's Not Just Honeybees That Are Mysteriously Dying The decline of bumblebees has received far less attention, though in the public imagination their plight has often been conflated with that of the honeybee. Not only do bumblebees pollinate about 15 percent of our food crops (valued at $3 billion), they also occupy a critical role as native pollinators. Plant pollinator interactions can be so specific and thus the loss of even one species carries with it potentially severe ecological consequences. As E. O. Wilson writes, "If the last pollinator species adapted to a plant is erased … the plant will soon follow." The cause: "the rise of the commercial bumblebee rearing industry in the early 1990s, largely for greenhouse tomato pollination. Captive bees, they say, played a key role in spreading disease, which has led to the decline of several North American species, all of which belong to the same subgenus."
