I think there is a simple way of ridding the world from g.m.o. Their should be a law saying that all those who support genetically modified organisms, in a direct or even in indirect manner, should prove their faith into it by eating g.m.o every day, during breakfast, lunch and dinner for at least a year. They would be medically checked to see the effect on their body.
And if they refuse, then they should be prosecuted for crime against humanity. Because that means, they know how harmful g.m.o can be, yet they still promote it, slowly poisoning the people to death.
