This is interesting seeing as using less pesticides is always one of the first pros listed while talking about GMOs. It is semi controversial because some people think that the genes from GMOs will spread into the wild population and could cause allergic reactions in human consumers. So far no reactions have been reported, and minimal occurrences have been reported of the wild population receiving the genes. As for feeding the growing population, GMOs can be "programmed" to grow with a lot more food yield than the original plant could provide. However, the problem will be more of preserving the food. Most of the impoverished areas dont have easy access to food, so unless preserving genes are added to the food, the amount of food generated will be worthless
