‘Fluoride is an extremely toxic chemical, and huge amounts were required for the manufacture of uranium and plutonium needed for nuclear weapons throughout the Cold War. Fluoride became the leading chemical health hazard of the US atomic bomb program. Then, in the summer of 1943, farmers downwind of the E.I. du Pont de Nemours Company chemical factory in Deepwater, New Jersey, began to report that crops were being affected by an unknown agent.
After a severe thunderstorm, poultry in the area died. Horses and cows were having difficulty walking and seemed stiff (a sign of fluoride toxicity). Farm workers who ate the produce they had picked began vomiting violently. Meanwhile, the New Jersey factory was producing millions of pounds of fluoride for the Manhattan Project, and unsurprisingly, a severe pollution incident had occurred.’
(At least most of the illness and death of people subjected to nuclear fallout has been caused by fluoride – you know, the stuff they are putting in drinking water.)
