What studies? Those aren't studies. That's just a giant bullet list of nonfactual shit thrown on a page with no studies shown at all. No sources. No peer review of the claims.
I could go through that line by line and likely refute every bit of it, but it's just not worth it. It's all based on one book actually. And it's nothing but BS meant to scare, instead of inform. On the author's page about the book, there's even a section called "Media Manipulation" in which he defends himself against how the "Media" has tried to attack him over his book. In reality the "Media" is calling him out for self publishing a POS book full of inaccuracies.
And apparently it's such a horrible incorrect book, that it's already been exposed for the completely nonfactual tripe that it is. There's a website already out there, that actually goes through this fool's claims line by line and provides correct scientific information about what your loony author is talking about. Wow... this POS is even more incorrect than I thought...
Here's the humorous dismantlement of all your "Studies" by Academic Review:
Genetic Roulette is Jeffrey Smith’s second self-published book in which he makes unsubstantiated claims against biotechnology. In it, he details 65 separate claims that the technology causes harm in a variety of ways. On these pages each of those claims – addressed in the same eight “sections” that correspond directly with the book – are stacked up against peer-reviewed science.
