Why Should the Public Care About What Happens to Honey Bees?
A honey bee, with pollen attached to its hind leg, pollinating a watermelon flower.Bee pollination is responsible for more than $15 billion in increased crop value each year. About one mouthful in three in our diet directly or indirectly benefits from honey bee pollination. Commercial production of many specialty crops like almonds and other tree nuts, berries, fruits and vegetables are dependent on pollinated by honey bees. These are the foods that give our diet diversity, flavor, and nutrition.
Honey bees are not native to the New World; they came from Europe with the first settlers. There are native pollinators in the United States, but honey bees are more prolific and easier to manage on a commercial level for pollination of a wide variety of crops. Almonds, for example, are completely dependent on honey bees for pollination. In California, the almond industry requires the use of 1.4 million colonies of honey bees, approximately 60 percent of all managed honey bee colonies in the United States.
