| We cannot do this in isolation because we never know if that would eg affect bird population or if we geneticaly modify mosquitos that can have unintendend consequences that no study can predict. Do not fool yourself that you can "make a study" for everything: you cannot. You can never predict what will happen if you mess with nature on a genetic level. This was already proven to be true when they released some GMO mosquitos which were not being able to reproduce. BUT WAIT! They were able to reproduce sooner or later again! How shocking! Who would have thought! And those scientists then said "this was not supposed to happen". These scientists got the problem completely wrong, up-side-down: they believed that they "studied" the problem enough. The believed that they "knew enough" that this "should not have happened". But they won't ever learn that complex system (which is pretty much everything in nature) cannot be "studied and come to a conclusion with a high degree of confidence". "High degree of confidence" and "complex system" are opposites that cannot appear in the same sentence. |
The GMO mosquitos are a good path because the direct consequences affect mosquito genes. If it is not effective enough, then we are back to poisoning the water with delta-endotoxins, where we know the consequences on things that are not mosquitos are far more severe.
