I don't know if any of you have watched More Than Honey, by swiss filmmaker Marcus Imhoof. Talk about amazing. It discusses the roll of bees in crops across the world, diseases and affects of impractical farming on bees, from the Almond growers in California to the Heather fields in Europe to China where they've hurt their bees so badly with chemicals that they are resorting to hand pollination for their other crops. The CGI is amazing, and it's really neat. If you have an opportunity to watch it, I highly recommend it. I know Graboid has it for download, which is where I got mine from.
