We are so screwed
Posted by Jill | 9:42 AM
The loss of honeybees would seem to be a relatively insignificant development as part of climate change, were it not for the fact that 1/3 of the U.S. diet depends on pollination:

Go to work, come home.

Go to work, come home.

Go to work -- and vanish without a trace.

Billions of bees have done just that, leaving the crop fields they are supposed to pollinate, and scientists are mystified about why.

The phenomenon was first noticed late last year in the United States, where honeybees are used to pollinate $15 billion worth of fruits, nuts and other crops annually. Disappearing bees have also been reported in Europe and Brazil.

Commercial beekeepers would set their bees near a crop field as usual and come back in two or three weeks to find the hives bereft of foraging worker bees, with only the queen and the immature insects remaining. Whatever worker bees survived were often too weak to perform their tasks.

If the bees were dying of pesticide poisoning or freezing, their bodies would be expected to lie around the hive. And if they were absconding because of some threat -- which they have been known to do -- they wouldn't leave without the queen.

Since about one-third of the U.S. diet depends on pollination and most of that is performed by honeybees, this constitutes a serious problem, according to Jeff Pettis of the U.S. Agricultural Research Service.

"They're the heavy lifters of agriculture," Pettis said of honeybees. "And the reason they are is they're so mobile and we can rear them in large numbers and move them to a crop when it's blooming."

Honeybees are used to pollinate some of the tastiest parts of the American diet, Pettis said, including cherries, blueberries, apples, almonds, asparagus and macadamia nuts.

"It's not the staples," he said. "If you can imagine eating a bowl of oatmeal every day with no fruit on it, that's what it would be like" without honeybee pollination.

Pettis and other experts are gathering outside Washington for a two-day workshop starting on Monday to pool their knowledge and come up with a plan of action to combat what they call colony collapse disorder.

"What we're describing as colony collapse disorder is the rapid loss of adult worker bees from the colony over a very short period of time, at a time in the season when we wouldn't expect a rapid die-off of workers: late fall and early spring," Pettis said.


While it's undetermined whether Einstein's famous quote about mankind having about four more years after the honeybees are gone is in fact attributable to Einstein, we know enough about pollination to know that if it doesn't happen, a lot of crops are in serious trouble.
