Chemtrails

I've been doing some online reading about the subject of chemtrails, and am providing some links to YouTube videos on it.

If you only watch one of the videos, this is the one to see.  It features pilots, doctors, and scientists speaking at a meeting of the Shasta Co. (CA) Board of Supervisors.  Their explanations are very concise and easy to understand.  The video runs a little over 15 minutes, and is really worth your time.

This one is a little over 12 minutes and contains a lot of scientific explanation, but enough practical info that anyone should be able to understand that the chemtrails are not good for us.

When you watch a YouTube video there is a list of similar topics on the right side of the page, so you can access more information on the subject if you so desire.  

One has to be careful with videos on YouTube as there is a lot of disinformation, conjecture, and downright garbage contained in many of them.  To my knowledge, anyone can get a YouTube account and put up a video, and lots of people do.  I respect the opinions of pilots, doctors, and scientists, and feel like the first video link above is important.

Somewhere in this video I heard one of the speakers refer to strange clouds in the sky that he had never seen before.  This is what I'm talking about - I am seeing such clouds lately, as well as formations that don't go together at all.  The puffy white clouds seen on a beautiful summer day just don't go with the black angry looking clouds that you see in a storm.

This is not just happening in California - it is happening all over the country.  Everyone should have some knowledge about what is causing it as well as the negative consequences already noted
