I found this video today in some of my internet travels. It's a documentary about "geo-engineering," and its effects on agriculture, food supply, and economics. Geo-engineering is a euphemism for weather modification, using chemical agents and other techniques. It sounds like science fiction, doesn't it? Unfortunately, I've become increasingly aware in the past couple of years that it might be "science," but in my opinion, it isn't fiction. For example, it doesn't take but a few minutes to find online the text of patents for technologies to modify weather. If people are patenting it, someone's doing it.
Now, a few years ago, anything that talked about geo-engineering or "chem-trails" got pegged as tinfoil hat territory. But lately it seems that many people are noticing evidence that something big has changed in the eco-system--increased respiratory disease, increased neurologic disease, increased severe weather events, changing weather patterns, and more--and the dots, when you follow them, seem to lead not just to run-of-the-mill pollution, but to geo-engineering.
Do yourself a favor and watch this film. After you watch, if you want to conclude it's craziness, be my guest. (If you're new to the subject, you might want to search for the predecessor to this film, called What in the World are They Spraying? first.)
