The problem is one of scope. With GM, traits are introduced in plants that stem from different kind if life, often bacteria that would never naturally be accessible using selective breeding. Plants that are resistant to herbicides for example. This is on one side a blessing - you can just spray roundup on your fields and the crop lives while the rest dies. On the other side, no one can predict the effect these changes will have on the ecosystem. I'm not very much concerned that GM food in itself is dangerous to consume. I'm far less certain that growing gene manipulated crops is as safe as it's made to be. What happens if two gene modified plants inter-breed? We've had enough accidents with "naturally" [1] selected plants and ruined a couple of ecosystems. We don't have that many ecosystems left. Add to that the whole economical dimension: Gene modified plants prevent farmers from creating their own seeds for limited gain. The ones profiting big time are monsanto and friends.
