What will we do without the bees?

I read an article today about the alarming decrease in the honey bee population and it really struck a chord.  The study concluded that the combination of a harsh winter and an alarming increase of pesticides present in honey bee carcasses are causing a dramatic decline in their population. 

This is frightening to say the least.  Honey bees are at the most basic level of our food chain.  Don't get me wrong; I'm concerned about polar bears, staggering poverty, starving children, and genocide as well but we can't survive without the bees.  This is a basic ecosystem equation.  We can forget all about modern convenience, connectivity, Ipads, and social media.  If we don't have the bees, we don't survive.

I'm not a doomsayer but is anyone else concerned about this?
