It's Bush's fault.
This has been going on for a few years. There's always a new mite of some kind or another killing the bees. I have a good friend that's a beekeeper hobbyist up in WA, and he gave up a while back because it was hard for him to keep the few hives he had alive due to the mites.
It's Bush's fault because he reneged on Kyoto so Halliburton could make profits.
