See this Agence France-Presse article, courtesy of Breitbart, about the mysterious decline in the bee population. If that sounds like something in which you cannot fathom having an interest, think again. Without bees, many crops on which we depend for food and clothing would not grow.
Called "colony collapse disorder," it is wiping out bee hives all over the world and neither scientists nor beekeepers know the cause or cure. The "greens" are strongly tempted to blame pesticide usage, and they may be correct. But they are guessing, just like everybody else. This is an issue to track in the next few years.
