The Real Threat

In the last few weeks I have, by implication, been called a murderer at least twice. Once was by Miranda Devine (with slightly more toned down versions by the usual suspects). She was alleging that environmentalists had sacrificed the lives of the people who died in Victoria's terrible bushfires by opposing fuel reduction burns. That very few environmentalists do oppose fuel reduction burns was irrelevant to her, as was the fact that the Victorian government seldom listens to the things the environment movement is pushing for anyway. Oh and that many of the most lethal fires went through areas that had been burnt recently anyway.

All this is old news. However, we've now had the spectacle of a Green Party member calling all those Greens who don't oppose flouridation murderers as well. Now I, like most of the fellow Greens I have spoken, to had a pretty open mind on flouridation. The opposition to her motion to condemn flouridation came from people who were concerned that process was being steamrolled and there was not adequate time to assess the issues. Only a handful had actually made up their mind in favour of flouridation.

I have read what appear to be intelligent arguements that conclude that overall the damage from flouride is larger than the benefit, and I was prepared to consider that these might be right. I knew that anti-flouridation campaigns had been discredited by some of the nutters who were involved, but tried to put this aside. Just because crazy people believe something doesn't mean it is necessarily crazy.

But the more the anti's spoke the more concerned I became. Many of the "facts" they claimed were things I was pretty sure were wrong. For example that the WHO was opposed. So I did a little research.

It didn't take long. I'm told National Greens policy on the matter is for a thorough inquiry into the issue, although I can't actually find it in our policy volume. However, if this policy exists its now out of date, because the NHMRC has done just such a study. It's a metastudy of all the recent research in the field (which is far more substantial than I had been lead to believe) and concludes that the only negative effects are aesthetic (discoloured teeth). As someone who suffers from this I don't trivailise its significance - if it affects one's love life it matters - but its certainly better than endless painful (and expensive) dentistry.

It's true that some studies have found small increases in serious conditions such as bone fracture rates in fluoridated areas, but even more have found reductions. Overall assessment is no net effect, and this applies for all the alleged forms of damage.

The important point here is not the issue of fluoridation itself. While the dangers are vastly less than opponents allege, it is also clear that the benefits are smaller than was originally thought, and are smaller still where good dental services exist. Much of the country has survived for many years without fluoride. If it was blocked it would not be a tragedy.

The danger is to the Greens. It is essential as a party that we make our decisions based on good science. The consequence of abandoning that path are all to clear in the last, unlamented, US administration.

This doesn't mean we should jump at every technology that has been proved "safe". There are arguments against Genetically Modified foods that go well beyond safety. Even if one considers the science settled here (and I'm not convinced it is) there is a case for opposition, at least temporarily. Even with fluoride, one can argue that philosophically people should not be forced to drink something they don't want, even if their fears are groundless.

But if we oppose these things we need to do it for good reasons, not because someone read something on an unreferenced website produced by an individual with clear mental health issues. If we go down that path we are in serious danger, because we will attract to the party people who don't understand how science works, and scare of those that do.
