We've got chemtrails to thank for that. The pollutants, that can clearly been seen in the classic image to the left, become a thin hazy cloud that eventually disperses dropping those toxic airborne poisons down into the soil, the water supplies, cattle, crops and mankind .... we absorb this toxic shit into us and become ill.
A simple fact. By design? Or by accident? By design is the more likely. More and more people falling ill due to airborne and soil absorbed toxins than ever before ... and its not mankind's pollution ... not the general populace anyway. Its the manmade SHIT that the hidden hand instructs to be dropped into the sky ... nice people not.
