Remove cancer causing agents from our food and water supply!

You see those signs around certain establishments claiming there are cancer causing agents in the caps of bottles or the linings of bags, etc. Our government knows these are harmful to all people yet they are still widely distributed and let's face it, that's because of economy. The extensive studies done that prove this also prove our best interests are not being considered. I wonder why anti cancer herbs and medicines are still fought against while so many products that are sold contain things like BPA or nitrites/nitrates. Remove the carcinogenic properties from our food and water supply!
