This paper is worth a read, even though I disagree with many of its conclusions. The argument is that when you're concerned about the chance that something can go wrong, we should distinguish between fat-tailed and thin-tailed probability distributions. A fat-tailed distribution is one where a particular event can dominate the distribution of outcomes and alter the system, whereas a thin-tailed distribution is one where no individual event is likely to fundamentally change the nature of the system. For example, evolution by natural selection has thin tails because even if something catastrophic happens to a group in a particular location, the geographic isolation of that group (for example; could also be some other isolating factor, like inability to transmit diseases across species) will limit the spread of the catastrophe. A nuclear missile launch has fat tails because there's a very likely chance it could trigger a global catastrophe. He argues that if we consider a system with a fat-tailed distribution that could result in complete devastation of the system (for example, total extinction of life on earth) then we should not engage in that action no matter how small the chance of the devastation is, because we value the devastation as infinitely bad. (And a finite number times infinity is still infinity.)
Taleb applies this to GMOs by arguing that the hybridization we have been performing until now has thin tails: if any one farmer tries a hybrid and it has dangerous side effects, that farmer will go out of business and the method won't spread past his farm. In contrast, he argues that the problem with GMOs is that we're essentially performing a global experiment, where wide swaths of the planet are being switched to the same crops in a very short period of time. If there is any chance at all of this going wrong, it will then go wrong on a very large scale and do something terrible like lead to mass starvation.
I think there are some obvious flaws with their argument, but I don't want to bias the discussion before people have a chance to consider the idea.

That's not unreasonable. A look at something like the banana industry is a pretty good example of using monocultures for global markets. I have no problem with criticisms of GMOs that are based on logic, as any system will require modifications over time.
