Interfering with nature how?
There have been serious infections before, were they to do with interfering with nature?
If you're worried about interfering with nature then what about climate change, nuclear weapons... ?
And I am sure this is against the spirit of the international conventions to do with this sort of thing.
You don't feel concern at the idea of experimentation on subjects that are part human?
What if they can survive? What if they could be 80% human 20% monkey?
You can't see the massive ethical can of worms here?
