The worlds population NEEDS to go down but these accusations are just out outrageous, "She was fired after making stuff up" Well I'm not surprised. Fluorine does improve your teeth and doesn't effect cattle, good proof of this is Queens Land in Australia, they don't have fluorine in there water and the majority's teeth conditions are worse then places with fluorine. These people are just as dumb as people who believe in religion, they said it so it MUST BE TRUE. Info if I was a parent of one of the students at your school I would have reported this nonsense to the principle, there's no need for this bullstuff getting into students heads, they should have they're own opinions of hole thing, and what I mean by that is if I teacher says it so then the students normally take that as a fact. Though he was only a sub-teacher I still wouldn't want him going back.
