IMO there is nothing sinister about GMO's, this kind of genetic manipulation is just the next step from the phenotypic breeding methods that have been employed for millennia. GM plants can benefit us by providing greater yields per hectare, more robust plants and plants that can produce higher levels of beneficial molecules, such as soluble fibres, than can be found in nature.
Where I have an issue is when commercial organisations such as Monsanto use bullying tactics in order to protect their patents and sell their brand of poison along with the seeds or even worse, impregnate their GM seeds with their toxic cocktails.
I think the world should just grow Avena sativa - there are no GMO oats.
