What's really going to send us to hell in a handbasket

As much as we're all rattling our sabers about global warming, when you read stories like this --> Honeybee die-off threatens food supply <-- it serves as a reminder of how delicately we are stitched into our ecosystem. Who would have seen something like this coming, for cryin' out loud? It will probably be something like this that wipes out the human race! Not melting ice, rising sea levels, greenhouse gases, cow farts, etc. It will be something as simple as a bee no longer pollinating the flowers that beget the foods that we eat. Call me a cynic if you want, but something tells me that we are at fault for the honeybee die-off just as we are to blame for every other cataclysm facing us. A virus killing off the bees? Yeah, the one and only "virus with shoes": people. You name it... on some level the human "race" is at fault.
