Marla Spivak reveals four reasons which are interacting with tragic consequences. This is not simply a problem because bees pollinate a third of the world’s crops. Could this incredible species be holding up a mirror for us?
Marla Spivak researches bees’ behavior and biology in an effort to preserve this threatened, but ecologically essential, insect.
