In the article, Kevin Hackett, the national program leader for the bee and pollination program at the U. S. Department of Agriculture (USDA), calls the massive honeybee disappearance “the biggest general threat to our food supply.”
What evidence from the article supports his claim?
Honeybees are not the only ones disappearing in large quantities.
Bees are used to pollinate many food plants, such as California’s almond crops, apple crops and citrus fruit crops.
The larkspur, a purple wildflower, requires pollination from its own species—other larkspurs—to survive.
Over 1 million bee colonies disappear every year, never to return.
