What's Wrong With The Bees?
Steve Kroft Reports On The Mysterious Disappearance Of Bees

Play CBS Video Video What's Wrong With The Bees Over the past year, some beekeepers have lost up to 90 percent of their hives. The losses could have serious effects because honeybees help produce a third of the foods we eat. Steve Kroft reports.

"David Hackenberg says, 'This product causes insects to lose their sense of navigation,'" Kroft tells Jeff Pettis. "And he says that's what's happening. He thinks they're leavin' the hive and can't find their way back."
"Well, if that's true, then we'll be able to find certain levels of different pesticides in those hives. And we haven't -- we don't have that complete picture yet. We just don't have consistency that points us in that direction," Pettis says.
Besides the pesticides, parasites, and pathogens, scientists are looking into the bees' diet and environmental stresses as contributing factors. Development has reduced natural habitat, clearing thousands of acres of clover and flowers. Instead, the bees are now spending week after week on the road, feeding on a single crop, undernourished and overworked.
"Doesn't bother the bees to spend that much time on the road?" Kroft asks Hackenberg.
"Well, I'm not sure if it bothers them or not," Hackenberg says. "You know, it's got to be stressful. I mean, everything we do has got to be stressful. But we've been doing this for 30 years."
"Beekeepers have been moving bees a long time. The Egyptians sent their bees down the Nile," says Dr. Marla Spivak, a professor at the University of Minnesota and one of the nation’s most respected authorities on honeybees.
Asked if the bees are getting stressed and if that's part of the problem, Dr. Spivak says, "Yes. They're stressed."
"Like everyone else," Kroft remarks.
"Like everyone else. They mirror us," she says, laughing. "We have a really close association with bees. They reflect what we're doing."
Spivak says bees are sensors for the environment, and they're giving us feedback. "You know the bees fly out. Either there is not enough food or it's contaminated," she says. "Then they come back into the nest and the nest is contaminated with diseases or mites, and so their whole environment is not healthy. And they’re saying, 'I can’t live here, it’s toxic.'"
It will take months, and possibly years, to figure out exactly what is killing the bees. Scientists are patiently trying to recreate colony collapse disorder in healthy hives in order to try and determine what’s triggering it.

This post must be a sarcastic joke. Nobody could actually be this stupid.

As I have written last year in the San Francisco Chronicle, March 10 and November 10, 2007, there is ample evidence to give genetically modified crops a closer look as one of the causes of CCD. My own research has shown that non-farmland bees thrive and produce more honey than their farmland peers. The honeybee issue obscures the more serious observation that ALL insect species are being affected. John McDonald
A: Used only on crops that would not attract bees, and don''t need to be pollinated by bees?
Rick, maybe God can just make us some more bees. Why don''t you ask next time you visit him?
"Religion is the sigh of the oppressed creature...It is the opium of the people."
Astounding that I have to actually spell things out, but answer is NEITHER. Darwin is simply stating the way nature works, period. Your value judgements show how ignorant you are of the world in which you exist. So, tell us all again, just what is your planet of origin?
