please explain, seems to me to be mostly about green politics.
Only one GMO (a bt corn I think) could be planted in the EU, and used mostly in Spain, though there's some hope the new rules will enable pro-GMO countries to plant many more in the future (approval process was generally stuck in the Council because enough countries opposed GMOs; now they can just ban them on their own territory w/o preventing pro-GMO countries from using it, and avoiding a conflict is politically attractive).
I personally see it as an ecological gain, due to productivity and so landuse improvements, something europe has basically stagnated at since these bans.
Sad to hear not much chance of improvements in the political sphere on that front..
