Should I be afraid of GMOs?

Pavitra

I was raised to believe that genetically-modified foods are unhealthy to eat and bad for the environment, and given a variety of reasons for this, some of which I now recognize as blatantly false (e.g., human genetic code is isomorphic to fundamental physical law), and a few of which still seem sort of plausible.

Because of this history, I need to anchor my credence heavily downward from my sense of plausibility.

The major reasons I see to believe that GMOs are safe are:

I would probably think they were dangerous even if they were safe, due to my upbringing.
In general, whenever someone opposes a particular field of engineering on the grounds that it's unnatural and dangerous, they're usually wrong.
It's not quite obvious to me that introducing genetically-engineered organisms to a system is significantly more dangerous than introducing non-native naturally-evolved organisms.

The major reason I see to believe that GMOs are dangerous is:

I might believe they were safe even if they were dangerous, due to "yay science" (which was also part of my upbringing).
We are designing self-replicating things and using them without reliable containment, thereby effectively releasing them into the wild.

So: green goo, yes or no?

According to the World Health Organization:

GM foods currently available on the international market have passed risk assessments and are not likely to present risks for human health. In addition, no effects on human health have been shown as a result of the consumption of such foods by the general population in the countries where they have been approved. Continuous use of risk assessments based on the Codex principles and, where appropriate, including post market monitoring, should form the basis for evaluating the safety of GM foods.

The reasoning most laypersons employ when thinking about GMOs is totally broken. For example, people worry about whether GMOs are less nutritious or unhealthy in some other sense. But there is no reason to think GMOs as a category would be skewed in any one direction, since any given plant might have different modified genes. It needs to be looked at in a case by case basis. Furthermore, GMOs aren't being developed in some Wild West free market. They are among the most carefully regulated substances you can ingest.

ETA: As for the concern about self-replication, that shouldn't be too serious of a problem. Domesticated organisms are optimized for thriving under human care, and pretty much every domesticated plant and animal does poorly in the wild.

Well said, thank you.

"In the wild" was a poor choice of words on my part; I was mostly thinking of contamination from one farm to another, "wild" only in the sense that nobody's in control of the phenomenon.
