Luddites

GM crops are banned in most of Europe, with the exception of GM corn, which is grown in Spain, quietly and without fanfare. Out of deference to the easily frightened, the stuff is not fed to humans but is instead fed to horses, cows, pigs, and poultry. That suffices to keep Europeans safe.

There is no conclusive evidence that GMOs are harmless to human health and the environment, which has led the World Health Organization to recommend that they be studied on a case-by-case basis.

There is no conclusive that anything else isn't harmful to at least some of the populace, but as long as a friendly judge can be found at a sufficiently high level, the rest of the populace can be forced to starve in the dark.
