As I have explained before ,the trails you see are contrails ,not deliberate poisoning by the govt. These trails are seen all over the U.S and elsewhere . How many hundreds of thousands of people would have to be involved in this alleged conspiracy? The limited tests done a long time ago were of relatively harmless agents and the purpose of the tests was to see how these agents would disperse if we were attacked by other countries. If you live out in the sticks like many curezone posters, you should be more worried about the effects of insecticide spraying since pesticides are most toxic right after they are sprayed before they react to form relatively harmless compounds.
