So here’s the story: a few days ago, Cara Augustenborg wrote an article for the Irish Examiner about Glyphosphate, the active ingredient in the the herbicide Roundup.

This raised some red flags with me and I said so on Twitter. What followed was a strong back and forth among me and some friends, and people who supported the article.

Cara has written a blog article in response, but in it she doesn’t really address the criticisms we had, and mainly restates her original points.

In her response, my suggestion that she went on a Gish Gallop is mentioned, alluding to a rhetorical style of proving one’s case through quantity of arguments rather than quality.

The thing is, I do care whether Roundup is rigid and dangerous. If the science weighs in that direction, I would be happy to see it being restricted and banned. I have absolutely no skin in this game as I really am not a farming or food expert, nor do I care either way about Monsanto.

The only thing I do know for a fact is that there is considerable debate in the scientific community about glyphosphate and it appears that the author is taking a position that is actually out of step with our current knowledge about the product. Minority views are fine within science, but they need a strong evidence base themselves in order to change minds on the matter.
The second thing that I noticed about the article was that it failed to give a hearing or acknowledgment to the scientific consensus. It’s a style thing, but it comes across as polemical and self serving. The entire article supports the view that glyphosphate is bad. It uses studies to support this, but there are more studies pointing in a different direction, and these are entirely ignored. It’s a style thing as it comes across as cherry picking, i.e., here’s my position, now here’s everything that supports my position, therefore my position is right. This is flawed logic. 
The last thing is that it doesn’t really address the food security question. If we remove it, what do we replace it with in order to ensure we can safely feed people? Honestly, if we get to a situation where we don’t need to spray crops to keep weeds and pests at bay, I would be very happy, so long as people have enough food. My understanding is that glyphospate is an important tool in the armoury. Let’s not replace it with something that’s worse for the environment, or something that puts global food supplies at risk.
