I think it should be banned. Yes, it is true that you can feed more people this way, but there have not been enough tests conducted on the safety of eating such food and its effects on the human body. And such tests should be run for years, because the effects might show up a couple of years or even decades or generations after the consumption of these. But the sad fact is that the big food producers are lobbying in favour of broader GMF acceptance. I personally try to avoid GMF but still who knows for sure what one buys from the food store...?
