You can find the document submitted by Mexico here: https://www.iatp.org/sites/default/files/2024-03/MexUSMCAInitialEng.pdf
On the point of transgenic varieties having a negative impact on local strain diversity, I think the concerns are valid. The introduction of high-yielding GMOs can lead to displacement of local varieties and ultimately decrease diversity.
I skimmed through the document to see if they make some good points about the health impact of GMOs. From what I can gather, the arguments are:
Glyphosate herbicides are commonly used when farming GMO corn. There is no global consensus on the potential long-term health effects associated with exposure to glyphosates and formulations that contain it.
Techniques to modify the genome are not perfect. Often, viruses are used, and some viral proteins could be inserted into the genome. Other things could go wrong. Ultimately, you may have an unexpected phenotype that turns out to make the plant toxic.
They argue that the GMO corn has a worse nutritional profile than native varieties. This worse nutritional profile ultimately has a negative health impact.
Personally... Maybe the glyphosate claim I can get somewhat behind but the other two health claims I don't find compelling. The risks over-stated, and their use of citations is not great.
I have an example of their use of citations that made me chuckle... They write:
And the citation reads:
Ah, well, thank you for that ๐
I'm glad you responded. I was really curious to see, as this smells more political than health related.
Yeah. Claims about potential health effects can be very persuasive.
It is a factual claim that something could go wrong, or that we have a gap in our understanding, and the outcome of that may be detrimental to our health. We can't disprove this because it is true, and so what we need to do is to assess risks in a balanced manner. It is also a factual claim that a de-novo mutation could occur and produce a toxic strain, or maybe we do not understand something about a plant that we commonly eat and we later find out that it is carcinogenic. Our understanding evolves over time, and risks are everywhere.
But most politicians are not so concerned with painting a balanced picture. The claim "a risk exists" is always factual and that is good enough to push an agenda.
In my opinion this does not in itself mean that one political position is better than the other. Maybe the health claims are not a good argument, but there are many other valid reasons to want to stop GMO corn.
I'm more suspect about the companies involved than the concept of GMOs to be fair haha.
Profit? What's that? No no, that's never a motive. We only want the world to be a better place thanks to our wonderful technology.
