Two thoughts - All food is genetically modified. If you look at agricultural practices from a historical perspective on long known “bread basket” areas, you will probably see this practiced manually for several hundred years. Wind, rain and other elements have probably helped the process since the dawn of the plant.
Second, this is my favorite quote:
Al Gore has worried, The most lasting impact of biotechnology on the food supply may come not from something going wrong, but from all going right
were far more likely to accidentally drown ourselves in a sea of excess grain.
So what if we do?
