You wonder whether there is a need for a moratorium. Reflecting good science and good scientific practices, the precautionary approach is part of that. That means if we do not have enough information but have enough evidence to believe there are risks—and some of the risks are severe—then it is good practice to say this should not be released until we have further information and knowledge. Exactly, that is a moratorium.
The Federation of German Scientists supports the moratorium as expressed by the CBD, and it's also my opinion.
Was your next question, what is the consequence if there isn't one and the technology is used?
