I think that looking at the GM plant business from the point of view of 'doom' or 'end of the world' is wrong. Probabilities are best for something along the lines of red algae, kudzu, or that other dog problem in Australia occuring again in a different way. Having really stubborn weeds that infest cultivable land would be close enough.
