How lethal are Chemtrails? What are they all about? Many are not even aware of their existence..First governments pretended they did not exist. Then they tried to pretend they were for our good. But the details of what they actually contained were mostly non-existent. I photographed Chemtrails over my house. This video is pretty comprehensive in detail. They seem to be spraying Barium and Aluminium dust, both toxic.
The why of it is what we don't know. It does have adverse effects on people with breathing difficulties or certain heart problems. So your guess is as good as mine.I don't think it is for any good purpose in any case.http://youtu.be/X3lW-TGGlk0
