I could be nuts on this. But if we can grow more and bigger crops, maybe stop some from starving that is good.
Higher yields can be achieved with normal crops as well. But right now, the major GMO producers such as Monsanto and Cargill are forming a monopoly, and they are almost forcing the farmers to use their GMO seeds. For example, smaller corn farmers in the USA, who use traditional seeds have been facing harassment from Monsanto for many decades now.
