If you pay attention to more immediate problems, like mercury fillings, vaccines, and the terrible diet most amercans eat, you will see the truth of what is causing this.
If Chemtrails even are a problem, I think there much more important problems. Have you even looked at the ingredants in a bag of snack chips or cookies recently? Or considered that many vaccines contain Aluminum, mercury, formaldahyde, or MSG? Or the fact that many electronic devices contain lead, cadium, and mercury and end up in our landfills, instead of being recycled?
