GMO have dubious benefits and the risks are fairly large:
Chemical fertilizers and pesticides and herbicides are totally unsustainable - because they use finite resources, and they kill off the natural processes in the soil *that we completely depend on*. This method of farming causes huge erosion problems and it poisons our water and causes dead zones in the ocean and contribute about 20% of our overall greenhouse gas emissions. And, we are using up the available deep aquifers, as well.
We cannot continue factory farming; for many reasons. GMO's are case-in-point to what we are doing wrong.
Climate change is forcing our hand, by making it obvious that we are farming in an unsustainable way.
