Fred Kirschenmann is an organic farmer who chooses not to plant genetically engineered seed. He shares his concerns about the use of genetic engineering in food production.

Transcript: Traditional Breeding

We've obviously been manipulating plant and animal organisms for a long time. The difference here is that we're now dealing with a new generation of technologies. It's not just genetic engineering, it's also robotics and nanotechnology. Each of these new generation of technologies are self-replicating. That is the basic difference. So that we're really setting in motion a dynamic there that we will not have control over because these are self-replicating. You can't pull them back; you can't stop them at some point and say o.k. that didn't work out and we don't want to do that anymore. So there are no exits here. That's the thing that's basically different. So in one sense...it's doing what we've always done. We manipulate things and try to get things to grow the way we want them to grow. But it's using a much more powerful technology now, so it is different.
