AlterNet: Environment: Colony Collapse: Do Massive Bee Die-Offs Mean an End to Our Food System as We Know it?: "What is so serious is not only that the bees themselves are dying off without a smoking gun present, but that most people have no idea of the role they play in the food supply at large. Commercial beehives pollinate over a third of America's crops, and that web of nourishment encompasses everything from fruits like peaches, apples, cherries, strawberries and more, to nuts like California almonds, 90 percent of which are helped along by the honeybees."

This is quite a disturbing phenomenon. In this article they mainly discuss the hives of commercial beekeepers, but this is also happening in the natural bee world. We could have serious problems if this trend does not change. Are our environmental practices to blame, or, possibly, our genetically engineered crops?
