(On the left-hand side of this poster, are the companies that contributed $46 MILLION, to defeat CA Prop 37, which was designed to force food companies to LABEL GMOs. On the right side, are those TRUE ORGANIC HERO companies, that donated $9 MILLION, to support legislation, CA Prop 37, which would require food companies to LABEL GMOs. You see, over the past several years, MEGA-Food corporations, like CONAGRA, Cargill, General Mills, Kelloggs,
etc., have been buying up small TRUE ORGANIC food companies, but, then, are now trying to stop people from forcing them to LABEL GMOs! They don't want you to know which foods have GMOs, because, if it were up to THEM, they'd just feed us all GMO crap, while serving true organic food, to their own employees, in their own cafeterias - like Monsanto does! BOYCOTT the companies on the LEFT-HAND side of this poster, and support, purchase from, those on the RIGHT-HAND side!)
