You've already heard about colony collapse disorder: Honeybees pollinate many of our crops; honeybees are in a state of precipitous decline; without honeybees, our food supply will decline, too. It's a frightening scenario, and if you happened to catch the latest news out of the U.S. Department of Agriculture, you were probably left with a sense of despair. "Bees are in more trouble than ever," warned The New York Times yesterday. "A quick federal survey indicates a heavy bee die-off this winter." Yikes.
Today, however, the same paper explained the situation in more depth, and -- as with most topics -- there's a good-news, bad-news angle here. Marcelo Aizen, a researcher at Argentina's National Scientific and Technical Council, and Lawrence Harder, a professor of pollination ecology at the University of Calgary, say that the truth about colony collapse is "not nearly so dire" as we think. For one thing, while certain crop-growing areas do indeed show a sharp decline in honeybees, the global trend indicates the domesticated honeybee is actually on the rise. Furthermore, not all crops are as dependent on pollination as we imagine. "Overall," the researchers write, "About one-third of our worldwide agricultural production depends to some extent on bee pollination, but less than 10 percent of the 100 most productive crop species depend entirely on it. If pollinators were to vanish, it would reduce total food production by only about 6 percent."
