Ban GMO foods, or require labeling? It turns out that the effect is almost the same.

I am not necessarily opposed to all GMOs foods, but each one requires careful testing and we can't trust a company to test its own product honestly. Meanwhile, for the sake of farmers' rights, we cannot allow the genes be patented.

We also cannot allow a GMO which is likely to contaminate other farms with the artificial genes. The likelihood of such contamination depends on the species of plant.
