Watch the video on Youtube and take note of what is written in the description.
During the World Cup and the Olympiads in Brazil I noticed that the sky had more Chemtrails than the usual.
This is anecdote evidence which is good for nothing. They deny that chemtrails exist so nothing was reported about it.
Go figure what these people have in mind. I don't understand but they have a lot of pleasure making people sick and enslaving those who are not their relatives. And money, of course.
