GM foods

"Genetically engineered organisms can combine with naturally engineered human bodies in bizarre, unexpected and tragic ways. We may have started to come to terms with the synthetic modification of life, but we still have a long way to go before we understand how the different parts of the natural and artificial worlds dynamically interact with each other in ways that we cannot anticipate. There's miles to go before we can sleep."

This is the reason why GM foods need far more testing than they have received. I can understand that Monsanto doesn't think that way, but that biologists don't understand this, I can't believe-- then why do so many of them swear by GM foods? There are other ways of increasing food production which can be explored-- vertical farms for one!
