The exact quote by albert einstein is, "If the bee disappeared on the surface of the globe then man would only have four years of life left."
This has not been verified, and is now considered a bogus quote.
People who use it are considered to be peddling popular tabloid superficiality.
It is early, pre-spring here, and there are plenty of bees around. We don't have that problem over here. But there is considerable concern that bee keepers are wasting time breeding up queens for overseas, instead of simply harvesting honey. I'm a big honey fan!
