2. Not 100% Environmentally Friendly
9. Gene Transfer
Relevant to the previous disadvantage, a constant risk of genetically modified foods is that an organism’s modified genes may escape into the wild. Experts warn that genes from commercial crops that are resistant to herbicides may cross into the wild weed population, thus creating super-weeds that have become impossible to kill. For genetically enhanced vegetation and animals, they may become super-organisms that can out-compete natural plants and animals, driving them into extinction.
