Here's a good article about dying Honey Bee's.
Honeybees Go on Strike (comic) by Mike Adams the Health Ranger
....The answer, of course, is because humans have turned planet Earth into a toxic world. We've poisoned the one thing in the universe that openly and unselfishly offered to give us so much for free. Yet instead of appreciating Mother Nature, we've chosen to betray her. We've turned what was once an Eden into a toxic world, and it's only a matter of time before the destabilizing, harmful practices we've adopted to feed an expanding human population come back to haunt us in a devastating way.
....The alarm bells are ringing, folks. We have reached the limit of the planet's ability to absorb our pollution and environmental devastation. I sadly predict the human species if not mature enough to make the necessary forward-thinking changes, and that it will only learn from disaster. That disaster is coming. Prepare to live in a world where food becomes desperately scarce. Prepare to see the human population collapse in almost precisely the same way the honeybee populations are collapsing.
As go the insects, so go humans.
