One persistent problem in commenting on scientific matters is that my knowledge is so limited in many areas I cannot tell serious science from politicised nonsense - but there are times when an example of the latter might make a mistake so blatant as to reveal the ignorance of the writers. Take as an example this this piece from the anti-environmentalist blog Not Evil Just Wrong.
This week he is in Uganda where he writes about Malaria and DDT. However instead of illuminating us on the subject he perpetuates the same worn out myths that continue to cause enormous death across the world.
We know a lot about Malaria in Uganda which kills 370 children a day. It is a painful death. It kills mostly pregnant women and children because it is particularly fatal to those with compromised immune systems.
But this death toll does not illicit an emotional response from Mr Jackson. However one aspect of this issue does alarm him. The use of DDT to stop the spread of malaria is a serious problem for Mr Jackson.
And so on - it's the standard old argument: That environmentalists are allowing children to die because they will not permit the use of the strong pesticides best suited to controlling the spread of malaria. I don't know if this is true or not - I'll admit ignorance on that. I don't know much about the commonality of malaria, the effect of intensive pesticide usage on mosquito populations, how long DDT lingers, how bioconcentration might effect it, or anything much about it's toxicity. On this issue I am completely ignorant.
The last line reveals that the writer of that page is just as ignorant though:
Perhaps the readers were alienated by reporters who shudder at the use of a harmless compound but remain emotionless at the daily slaughter of 370 children.
Harmless? DDT is harmless? Now, I don't know exactly how harmful it is, but I am quite sure it cannot be fairly described as 'harmless.' If it were harmless, there wouldn't be any debate over this at all. The very purpose of DDT is to kill insects, and it only takes a little googling to find a long list of suspected or confirmed long-term effects. The UN classes it as "moderately toxic" and the WHO as "moderately hazardous."
So when NEJW calls DDT "harmless" this is clear evidence that the writer has no more knowledge of the subject than me - that he is making scientific claims, while unfamiliar with even the most basic areas of the science.
What this mistake tells me is that NEJW isn't attacking the ban on DDT because they have analysed the numbers and determined the lives lost to malaria outweigh the lives saved and environmental gains. They are attacking the ban on DDT because environmentalists support it, and what environmentalists support, NEJW is obliged to oppose.
This fits in very well with the NEJW style. My characterisation of it as 'anti-environmentalist' was not intended in sarcasm. The purpose of the blog is to promote a film of the same name which criticises the environmentalist movement for placing the interests of conservation above those of economic development. It's a well-deserved criticism, but if the intellectual standards of the blog are anything to go by, I would not trust the film to be honest or trustworthy either. I have not yet seen it, but to base my judgement on the writings of it's associated website I would expect it to contain lies, emotional manipulation, personal attacks and mockery rather than honest analysis in the scientific flaws of prominent environmental policies.
