Mutant NInja Super Weeds

Bio-engineered food does not exist in isolation; there is a lot of cross pollination that happens in the real world. If that is not enough of a concern "Lab studies suggest that some transgenic plants are as much as 20 times more likely to “outcross” with other species. Moreover, species with different numbers of chromosomes have hybridized and produced viable offspring – something previously thought to be nearly impossible."
The result can be super weeds resistant to everything nature and science at them.
