Btw: The photosynthesis modification that boosts biomass production in tobacco looks like one of the better GMs, genuinely promising: it involves code already present in plants of the same general kind (the safety of long experience), it produces essentially nothing not already present in these plants, it is probably self-limiting in the wild, and it is possibly the first likely GM that would actually fulfill the common promise of greater intrinsic yield per acre in some crops (it pays for itself, a net gain in production). It is intrinsically safer and more promising than most GMs, especially in a crop plant. Even so, whether it is "safe" or not in any given O would need to be checked. Any GMO incorporating it would need to be checked. GMOs are not safe.
