IN the debate about adding sodium fluoride to our drinking water, only the alleged effects on children's teeth is mentioned but never the effects on the total ecological system.

Dumping tons of this toxic waste anywhere would, if the offender was caught, result in heavy fines and possibly a prison sentence. How much easier to dispose of it if people can be persuaded it may have beneficial effect on their children's teeth.

When fluoride occurs naturally in water supplies it is in the form of calcium fluoride which is totally different from sodium fluoride. It is thought that it may be the combination of fluoride with calcium that may benefit children's teeth.

No-one ever mentions exactly how much sodium fluoride a child needs, to consume if it is to benefit from it or how much before it suffers detrimental side effects. so how about the experts giving us some figures?
