This article from the Independent talks of a possible link between the disappearance of bees and radiation given off by cell phones.
The theory is that radiation from mobile phones interferes with bees' navigation systems, preventing the famously homeloving species from finding their way back to their hives. Improbable as it may seem, there is now evidence to back this up.
Colony Collapse Disorder (CCD) occurs when a hive's inhabitants suddenly disappear, leaving only queens, eggs and a few immature workers, like so many apian Mary Celestes. The vanished bees are never found, but thought to die singly far from home. The parasites, wildlife and other bees that normally raid the honey and pollen left behind when a colony dies, refuse to go anywhere near the abandoned hives.
Bees are vital to pollinating crops that feed us all. Without bees, and there is a worldwide shortage of bees, food supplies would begin to dwindle. The article mentions a statement from Albert Einstein who once said that if the bees disappeared "man would have only four years of life left".
An interesting article.
