This article has a little of all three.
"Albert Einstein once said : 'If the bee disappeared off the surface of the globe then man would only have four years of life left. No more bees, no more pollination, no more plants, no more animals, no more man.'
Apocalyptic for sure. We haven’t reached that point yet, but some worrisome indicators suggest dramatic drops in the bee population of the US are likely to impact crop production. This is not a small agricultural sector that is being impacted either. In the US bees pollinate more than $14 billion worth of seeds and crops each year.
The disappearing bee phenomena isn’t restricted to the US. In Europe countries are experiencing varying degrees of what investigators describe as “colony collapse disorder” (or CCD). Countries effected include Germany, Switzerland, Spain, Portugal, Italy and Greece. However the most serious losses have occurred in the US. On the West Coast keepers have seen bee population losses in the 30 to 60 percent range. On the East Coast and Texas it gets as high as 70%. These are catastrophic drops for an industry that considers around a 20% population decline to be an off-season norm."
