This may be another silly story worthy of a few outraged picket lines. The only problem is that the product being protested is hardly something most people can avoid: money.

Turns out, people who have laughed at the Euro as “fake” currency may have struck a nerve: many Euro notes are printed on genetically modified cotton. To the horror of some Europeans, according to the British News, “the engineered banknotes are not even labeled.”

Will people blame the United States for this environmental shakeup? Most of the genetically modified cotton sold to print Euros comes from America, it seems. Despite the lack of health risks associated with using modified Euros, some people are outraged.

What to do now? Extremists advocate complete elimination of all genetically modified products in Euro notes, while more moderate voices promote labeling of modified money.
