Wow. Thanks for that link, Don Firth. I had no idea of how much knowledge I was lacking.

And it explains chemtrails too! "It has also been theorized that seed crystals have been sprayed from military and possibly civil aircraft in the form of so-called "chemtrails", which then enter the body of a host via the food and/or water supply or direct dermal contact."

No wonder there's so much fear in the world.
