I’m pro-GMOs, so you could say it’s typical that I’d like this book, and I’m really the only kind of audience it would reach — but I think Lynas is genuinely attempting to dispell myths and introduce other people to the actual science behind GMOs, for all that. He was himself once very much anti-GMO, and participated in the crop destructions and demonstrations against people who tried to grow genetically engineered crops in the UK; he was “converted” by actually looking into the science behind it, and finding that behind the scaremongering, there’s very little real science.
He does also (perhaps somewhat weirdly) mount a defence of Monsanto; some aspects are like a case study of the problems of GM crops in action, but at other times he seems to be conflating the rise of GM crops as a whole with Monsanto — not quite the same thing; one doesn’t need to defend Monsanto to prove that GMOs are no threat. (Although he’s also not wrong that many of the kneejerk claims against Monsanto are on shaky ground. For example, the idea that Monsanto deliberately sell sterile seeds in order to force farmers to purchase new seed every year. That idea is just poor understanding of genetics: the second generation of seed may not actually carry the Roundup-resistant gene, in the same way that the seeds of hybrid crops don’t necessarily breed true.)
Lynas writes well and clearly, and often evocatively; his struggle with becoming pro-GMO isn’t drawn out in angsty detail, but it’s plain that it wasn’t an easy change for him and that he made the decision based on facts he could no longer ignore. Perhaps for some people, his presentation of the known facts will be enough to tip the scales. I’m somewhat doubtful (I think a lot of people who are anti-GM will automatically reject this book as being by a sellout, particularly because of the defence of Monsanto), but maybe it’ll help. If you’re on the fence, it should definitely help to clarify your views.
