It seems that one day Albert Einstein would have said : "If the bee were to disappear from the face of the globe, the man would only have four years to live ". Although we have no way of knowing if this sentence is from him or not, at least it has the merit of being clear : without bees, more human life. From now on, we can also say "If the wasp disappeared from the face of the globe, viticulture would only have four years to live ".
