What happens to people when they become government science advisers? Are their children taken hostage? Is a dossier of compromising photographs kept, ready to send to the Sun newspaper if they step out of line?
I ask because, in too many cases, they soon begin to sound less like scientists than industrial lobbyists.
The mad cow crisis 20 years ago was exacerbated by the failure of government scientists to present the evidence accurately. The chief medical officer wrongly claimed that there was “no risk associated with eating British beef.” The chief veterinary officer wrongly dismissed the research suggesting that Bovine spongiform encephalopathy, or BSE, could jump from one species to another.
The current chief scientist at the UK’s environment department, Ian Boyd, is so desperate to justify the impending badger cull — which defies the recommendations of the ￡49 million (US$76 million) study the department funded — that he now claims that eliminating badgers “may actually be positive to biodiversity,” on the grounds that badgers sometimes eat baby birds. That badgers are a component of our biodiversity, and play an important role in regulating the populations of other species, appears to have eluded him.
However, the worst example in the past 10 years was the concatenation of gibberish published by the British government’s new chief scientist on Friday last week.
In the Financial Times, Sir Mark Walport denounced the proposal for a temporary European ban on the pesticides blamed for killing bees and other pollinators. He claimed that “the consequences of such a moratorium could be harmful to the continent’s crop production, farming communities and consumers.”
This also happens to be the position of the UK government, to which he is supposed to provide disinterested advice.
Walport’s article was timed to influence last Monday’s vote by European member states, to suspend the use of three neonicotinoid pesticides. The UK, fighting valiantly on behalf of the manufacturers Syngenta and Bayer, did all it could to thwart the nations supporting the partial ban, but failed.
Here is how he justified his position.
First he maintained that “there is no measurable harm to bee colonies ... when these pesticides have been applied on farms following official guidelines.”
This statement is misleading and unscientific. The research required to support it does not exist.
The government carried out field trials which, it claimed, showed that “effects on bees do not occur under normal circumstances.”
They showed nothing of the kind.
As professor Dave Goulson, one of the UK’s leading experts, explained, the experiment was hopelessly contaminated. The nests of bumblebees which were meant to function as a pesticide-free control group were exposed to similar levels of neonicotinoids as those in the experimental group.
The government “might have been wise to abandon the trial. However, instead they chose to ‘publish’ it by putting it on the Internet — not by sending it to a peer-reviewed journal. This is not how science proceeds,” Goulson said.
What this illustrates is that these trials have taken place far too late — after the toxins have already been widely deployed. The use of neonicotinoids across Europe was approved before we knew what their impacts might be.
Experiments in laboratory or “semi-field” conditions, free from contamination, suggest that these toxins could be a reason for the rapid reduction in bee populations. We still know almost nothing about their impacts on other insect pollinators, such as hoverflies, butterflies, moths, beetles and midges, many of which are also declining swiftly.
