Another reason to oppose GM:
where the engineered bacterium was growing, all the plants were dead.
Later we tried this experiment using several different kinds of soils, but the result in every case was dead plants.
Take that information and extrapolate it to the real world. Given that the parent organism lives in the root systems of all plants, what's the logical outcome of releasing this organism into the natural environment?
Very possibly, we would have no terrestrial plants left. Some plants, such as riparian and wetland plants, have mechanisms for dealing with alcohol production in their root systems. But the logical extrapolation of that experiment is that we would lose terrestrial plants.
