@zleap i don't know about the atrazine but there is a bunch of (once) common chemicals which either act as or disrupt hormones, often with bigger impact on males, like BPA and PCB. that's no conspiracy, it's why childrens products are advertised as BPA free.
almost no country does fluoridation of tap water anymore. fluoridation doesn't make much sense when there are topically applied fluorides in toothpaste where the risk of overdosing isn't as big. there was a recent us federal ruling that the epa has to regulate fluoridation of drinking water because it might have negative impact on intellectual development of children.
