Here's another reason to stock up on the food reserves. I heard about this problem with the bees a while ago, but the article linked here talks about the continued effects of not having enough bees for food production. For me, the possibility of no food being available at all is a lot scarier than the rising food prices, which are scary enough by themselves. Lack of bees affects large crops and backyard gardens alike.
Fewer bees means less honey by association, and honey is an excellent food storage item. If you store it correctly--cool enough conditions--it can last for years. It's about 1 and 1/2 times sweeter than sugar. Hey, it can't hurt to have your food storage taste good, right? :)
