I remember covering this news story a week or so ago.
In my opinion I think concerns about GE food being unhealthy is bollocks. Humans have been genetically engineering food for centuries. Did you know the dominant colour of carrots used to be purple? The thing is now we're that much more efficient at it, what used to take generations of crops now takes only one generation. The fear is that this speed means safety checks haven't been done properly. Really though there's no reasons not to trust the CSIRO's judgement and I don't see how GM food is any more or less risky than any other food.
However a point raised by a Greenpeace rep in an interview caught my interest. She said that the funding for the CSIRO project could be linked back to Monsanto. This interested me due to the huge power Monsanto has over soybean crops. Monsanto engineered a soybean that was resistant to their pesticide product RoundUp. The crop became very popular but due to the patent they had on it, farmers were unable to save their seeds, a regular process in agriculture, and had to buy new seeds from Monsanto all the time so the company could keep making a profit. Any farmer found to be or even suspected of saving their seeds was sued and, due to the financial and legal power of Monsanto, lost every time. This is made worse due to the fact that because of cross-contamination, modified Monsanto soybeans were growing on farms that didn't opt to use them, meaning Monsanto could sue people for 'stealing' their product even if the farmer had no idea about it. This whole mess is outlined far more thoroughly in the documentary Food Inc. which is a good watch.
It would be awful if Monsanto got this same power with wheat crops. I don't think it's right for a corporation to have such control over such a staple food while financially crippling those who produce it. So yeah, if that's Greenpeace's angle then to a certain degree I support them.
But this isn't Greenpeace's angle. With them it's all about man vs. mother nature and fear campaigns about how GM food is unsafe. Sigh.
