None of you at getting the point of the OP. I now have a Michael J Fox level of GMO understanding smart phone. So now I can become blunt.
How safe are the various GMO methods? These are the methods I know about.
Transformation:
mutation breeding by exposing the plant to radiation
gene gun which bombards the plant with particles
Selection:
After transformation, the majority of the cells are still the original. The whole organism is exposed to either a pesticide or antibiotic(sometimes both) which kill the non-selected cells, leaving only selected. Once the transformed cells are the only ones left, they're regenerated using plant culture methods.
Here are the concerns. Those cells are part of the genome. The selection genes have no purpose but for a parasitic take over during development. Our freedom fighters against world hunger promise selection genes cannot cross over to other species, such as bacteria. But, it has been shown in optimal lab conditions, it can cross with bacteria. Why this is a problem, is when our friendly gut bacteria get transformed, they no longer perform their proper function and we humans can no longer acquire all our nutrition.
GMO is designed to be used with pesticides, anti-fungals, etc, which can become pretty nasty. They're not designed for conventional farming methods. Monsanto has enough money they can silence their mistakes which have cost lives, such as livestock death.
bunny, nobody is arguing for the texas sharpshooter approach to gene splicing, not only is that method super expensive to use, it provides moslty hideous mutations and freakish monstrosities that die moments after their trip through doctor brundle's teleportation booths.
gene splicing is done with care, under carefully controlled conditions, nobody simply tosses critters into the gamma ray chamber to see what will happen.
most GMO products flop anyhow due to the lack of buyers confidence, and the prohibition on these products by the EU and other transnational groups and nations.
in fact i cant think of a single commercial success with GMO products outside animal feed cotton and other non-human food products.
shit, the flav-r-savr tomatoe was such a dismal failure that you would be hard pressed to find anyone who actually ever tried one.
on a personal note, i tried the Flav-r-savr tomatoe in the 80's or the 90's...
it tasted like crap. the premise was to create a tomatoe that could be refigerated without losing it's flavour. their "success" was making a tomatoe that tasted like it was already refrigerated, and thus mealy, and bland even when totally fresh.
this was not huge success, this was fail.
it did not however taste like fish, despite having fish genes spliced in, nor did i become a hideous monster with a craving for human flesh (at least not any more than usual)
eating genetically modified foods will not turn you into a mutant any more than eating regular foods will turn you into a carrot.
contrary to the popular (and hysterical) assumption, eating a thing does NOT incorporate the genetic material of that thing into your own genome. if that were true, echelon would actually BE a giant syphilitic kangaroo cock.
