YUROPIANS be like

Coming to a peaceful resolution

FREUDE!

Sure. Cancer also exists in nature. Problem is not weather it's natural, or healthy to the end consumer. Because GMO is safe to eat (to the point, but that's different topic). Point of those regulations is protecting local flora and fauna, so that stringer, modified species don't overtake their natural counterparts. We don't know all of the natural processes, we don't know ecosystems so well to be sure that our small continent, with very dense population can't withstand even smallest biological disaster.

To give it an example: genetically modified sunflowers are planted in Spain. Because they are seeding by birds eating them and pooping out the seeds somewhere else, they rapidly spread across Iberia and France. We have modified them to grow faster, seed faster and to be immune to most pesticides, bugs and things that normally regulate their expansion. Because of this we have to use chemicals to stop them, and doing that we kill local plants, maybe even poisson the ground. Ecosystem has been destroyed, and consequences can't be foreseen. We have a problem.

It's better when we don't have a problem. In US this may work, they can, and have plantations of GMO corn for example, that are far away from fertile grounds, and so those can't seed in random spots destroying local eco systems.

In Europe we had one such disaster, back in a day. Sosnowsky's hogweed was an invasive plant, although not GMO, they were able to adapt extremely quickly to the new ecosystems, destroying fields, farms and even sometimes hurting wild animals. They were also dangerous to humans, as their were burning their skin upon contact.

The plant was common only in the Caucasus area, until it started to be used as a silage plant in other parts of the Soviet Union. As a result, it quickly spread in many areas of Russia, Belarus, and Ukraine. It is now a highly invasive plant in the Baltic States, Poland, and Belarus. Many river valleys and roadsides are occupied by large stands of this weed. It is difficult to eradicate because the seeds remain viable for many years and the roots are difficult to remove. Herbicides are widely used in a fight against it, but the plant can later resprout from the roots.

The decision to use the plant for silage was made in 1947, under Stalin's rule, so when the species later proved to be highly invasive and difficult to remove, people started to call it "Stalin's revenge".

So. Reassuming: regulations against GMO are to protect the ecosystems, not directly costumers. There are also regulations that are basically sanctions that help local producers against foreign cheaper products.
