safe in perpetuity
Ain't no such animal.
I don't think that looking for forever guarantees is a useful exercise. The point was really the double standard applied to GMOs.
I agree: there is no "forever guarantee," especially as our life spans increase to experience new problems and our ability to detect problems improves, we discover new things that may be killing us or may have been harming us in the past.
That said: I'm unclear on the double standard you were pointing out. Was it something that I said indirectly? If that is the case, the point of my statement is that we have a longer body of evidence for traditional food engineering (selection, cross-breeding, etc) than we do for direct genetic modification by sev...
Basically: How does one pursue the truth when direct engagement with evidence is infeasible?
I came to this question while discussing GMO labeling. In this case I am obviously not in a position to experiment for myself, but furthermore: I do not have the time to build up the bank of background understanding to engage vigorously with the study results themselves. I can look at them with a decent secondary education's understanding of experimental method, genetics, and biology, but that is the extent of it.
In this situation I usually find myself reduced to weighing the proclamations of authorities:
