It is a big worry. About three quarters of the food in our grocery stores is pollinated by honeybees. Some beekeepers have lost as much as 75% of their hives. No one knows for sure what causes it, and there is much speculation. One source even suggested that cell phones were to blame (they're not). Researchers are keen to find the cause, as it is very injurious to the hives. They are not finding dead bees anywhere, so that is part of the mystery.

If you don't care for reality, just wait a while; another will be along shortly. --A Rose
