Glyphosate and the Gut Microbiome: Another Bad Argument Annihilated

Introduction:

Glyphosate is a broad spectrum herbicide that was first introduced by the Monsanto company in the 1970s under the brand name Roundup. The already popular product grew even more popular among farmers upon the introduction of various commodity crops which were genetically engineered to resist the herbicide while it killed the surrounding weeds with which the crops would otherwise compete for water and nutrients. Glyphosate went off patent back in the year 2000, and since then many manufacturers have cashed in on its popularity [1]. Although it is of unusually low toxicity, glyphosate receives a level of scrutiny and vehemence of criticism that is disproportionate to its actual established risks [2],[3],[4]. This is attributable in part to its ubiquity in modern conventional farming, but it's likely even more attributable to its association with Monsanto, against which a large and well-organized counter-movement has emerged [5].

Argumentation

The One True Argument™

Anyone who has spent much time addressing a lot of myths, misconceptions, and anti-science arguments has probably had the experience of some contrarian taking issue with his or her rebuttal to some common talking point on the grounds that it's not the “real” issue people have with the topic at hand. It does occasionally happen that some skeptic spends an inordinate amount of time refuting an argument that literally nobody has put forward for a position, but I'm specifically referring to situations in which the rebuttal addresses claims or arguments that some people have actually made, but that the contrarian is implying either haven't been made or shouldn't be addressed, because they claim that it's not the “real” argument. This is a form of No True Scotsman logical fallacy, and is a common tactic of people who reject well-supported scientific ideas for one reason or another. In some cases this may be due to the individual's lack of exposure to the argument being addressed rather than an act of subterfuge, but it is problematic regardless of whether or not the interlocutor is sincere.

Genetic Engineering and the Emergence of Herbicide-Resistant Weeds

One of the more common criticisms leveled against Genetically Engineered plants, particularly Herbicide-Resistant (HR) strains, is that they are purported to lead to what critics refer to as "Superweeds." The term superweeds is not a scientific term, and can be very misleading to people not familiar with the science. What is really meant by the term is the event in which local weeds become resistant to a particular mode of action undertaken by the farmer for the purpose of weed control. For instance, local weeds might evolve a resistance to a particular herbicide is it's used often in the areas in which they grow. There's nothing "super" about the alleged superweeds other than the fact that they've become resistant to one particular method. (more…)
