Are we being poisoned by our own government?

  

     Are we being poisoned by our own government? If jet fuel is so corrosive what is the difference between a normal vapor trail and chem-trail? Why do you not see chem-trail's at night? Are the long-term effects as bad as nuclear fallout? Why is Monsanto's developing plants that are resistant to soils that are contaminated with aluminum? If the government says they have never done such a thing, what about agent orange and other chemicals that were sprayed during the Vietnam War? Why does the government refused to talk about geo-engineering?
