>Probably 99.99999% of GMOs are fine, but that one in a million will have disastrous consequences for an ecosystem.

This really doesn't make any biological sense and kind of goes against all of our understanding of evolution and ecology. Can you describe this theoretical situation in any kind of detail? I find it completely incoherent and unimaginable.

GMOs have a huge advantage over traditional methods of crop development because they can be engineered to be safer: they can be designed to not survive off of human farms, and not reproduce with wild plants, or have other safety measures.

The idea that we can create a single organism that could cause an ecological catastrophe (bigger than any of the ecological harm caused by simply moving around invasive natural species) is science fiction; the idea that we could do so accidentally while trying to create food to eat is a complete delusion. We've already created outlandish, strange, non-natural super plants: every single vegetable that you and I eat. We did so with no regard to safety, nor understanding of what we were doing. GMOs only improve enormously on this process.

Again, the utter failure of this argument is apparent in how it can be applied to any technology: we shouldn't make software because that 1 in a million program could destroy the power grid / Internet / cause nuclear war, we shouldn't make medicine because that 1 in a million vaccine will cause people to drop dead en masse 10 years down the road, etc. If those seem preposterous to you, I assure you that to plant scientists, geneticists, and EcoEvo folks, your worry seems equally preposterous.
