But the long term effects of GM crops have not been properly researched
They've been independently researched by many scientists, organisations & universities for years, and bugger all has been found wrong with them, and nor will anything be found, as it is just another form of cross-breeding/natural selection.

I'd be more worried about plastics, and the fact it is PROVEN to reduce fertility in men & women, as well as causing some cancers, and yet try and avoid plastics.
