Re: Chemtrails the myth is funny stuff.
Fluoride in the water is well documented, and widely known, although it is anything but healthy, same for mercury in tooth fillings, also well known, pharma drugs, also well known. Pollution, well known, and people are contributing to this everyday. All the things you mention are avoidable by people, you can filter your water, get different types of fillings in your teeth, not take pharma drugs, and stop supporting polluters, and stop adding pollution.
There is no evidence that they are spraying anything at all, look at aviation
Science and engineering, physics, geology, atmospherics, chemistry etc, and you will see that what people are seeing is not spraying from planes at all.
I think chemtrails are simply another internet myth, just like many others, they may sound plausible, but when you look deeper into these theories, they don't add up.
Have a good day at work Chaz, I'm off to bed :)
