87. GMO Babies and Foods

26 Jan

I recently listened to a TED talk entitled “The ethical dilemma of designer babies”, by Paul Knoepfler. It was a good talk, but I was disappointed by the suggestion of a moratorium on the science involved in the direct genetic improvement of reproduction.
Knoepfler is a scientist working in the field of genetics and GMOs (genetically modified organisms). He discusses the possibility that in 15 years or so, we will be able to make “designer babies” that are free of genetic diseases and may also have improved looks and intelligence. The author is afraid that “natural” children will be upset by the successes of “designer” children.
I think the “designer” idea is great and is not so strange as some think. After all, we affect the success of our children in many ways, including medical methods such as plastic and corrective surgery, good nutrition, the best education, exercise, mental health, etc. — why not give them an even better start by improving their DNA through carefully studied and regulated procedures.

Aside from the talk, I am also concerned about irrational fears of GMO foods, which are really important for the survival of our growing populations. Here is what I wrote about these methods as a comment to the TED talk:

I am a scientist (retired, and not in the field of genetics) but still study many areas of science and am very interested in scientific progress.   My judgment is to forge ahead in any scientific area, but observe certain limitations.  If there is a clear possibility of danger then we need responsible transparency and monitoring, not moratoriums.  I live in and am a citizen of the USA.  It’s foolish for us to stop working on something potentially very beneficial  while all over the world others are progressing and benefiting. At a minimum, just preventing genetic diseases is very worthwhile.  A moratorium here just puts us behind scientists working in other countries, and does not prevent the dangers that the speaker hints at.  Rich people, of course, would be able to take advantage of this overseas, and ordinary people would not.   My idea is to reject timid and fearful limitations and go full force,  using good documentation and studies as guides.  If it becomes clear that advances such as “designer babies” or certain GMO foods are dangerous, then scientists and Congress can regulate or abolish the procedure. 

The speaker is worried that a “natural” child would have to compete with a “designer” child. But even without this method there will always be someone better than you. It is not a good argument. Nature, breeding methods, cosmic rays, and even choice of a spouse all cause genetic (DNA) changes. The advantage of direct DNA changes by scientists is that they CAN be monitored and procedures can be improved or limited.

The innovations and amazing discoveries of science are a great joy. In a world filled with kindness and intelligence, scientists would never have created atomic bombs. Traditions, rigid beliefs, ignorance, and greedy politicians HAVE caused world disasters — Science has not.
After writing the comment, I decided to read more about GMO use. It is hard to do human research on GMO’s, but there are good studies using animals, that, in fact, we eat. Jon Etine (Sept 19, 2014, Forbes) reports:

“Estimates of the numbers of meals consumed by feed animals since the introduction of GM crops 18 years ago would number well into the trillions. By common sense alone, if GMO feed were causing unusual problems among livestock, farmers would have noticed. Dead and sick animals would literally litter farms around the world.”

There also is formal research that shows no negative effects and no effects on humans eating these animals. Irrational fears about GMO’s are unproductive and harmful. Of course, specific findings on particular GMO’s should be acknowledged, but should not influence the whole field. We don’t avoid all doctors, because a few have been convicted of malpractice. We need to use the results of good responsible scientific research wherever it is helpful. It is ignorance and unethical politicians that have caused our widespread dilemmas.
