Nuclear Proliferation and the Debate Over Eugenics
This weekend the Globe and Mail published a feature called Unnatural selection: Is evolving reproductive technology ushering in a new age of eugenics?. The article was written in response to the ever-growing practice of using in vetro fertilization (IVF) to screen for genetic disorders. IVF, a technology originally developed to help couples conceive, is now being used by doctors to analyze the DNA of embryos before implantation in order that those which carry chromosomes responsible for serious illnesses or developmental defects may be discarded. This practice alone should be cause for debate, but the more serious concern is that following the development of this technology the only thing left between human beings and genetic engineering is ethics.
In practice there is no difference between discarding an embryo because it carries the chromosome for ALS or discarding embryos which don’t carry chromosomes thought to be responsible for increased intelligence. For those who believe that the latter is science fiction, think again. Still in the early stages of development there already exists microchips that can test a genome for well over a thousand traits, such as “heart disease, seasonal affective disorder, obesity, athletic ability, hair and eye colour, height, susceptibility to alcohol and nicotine addictions, lactose intolerance and one of several genes linked to intelligence.” The recipe for the “perfect child” is not far off.
This is all proving to be exciting news for hopeful parents, many of whom have inundated labs practicing this research with requests for chromosome selection. As moral argumentation is now the last line of defense against the uninhibited pursuit of eugenics it is imperative that the utter foolishness of this shortsighted and self-interested behaviour be recognized. Our history offers no shortage of examples of technologies that, heralded upon their invention, later proved to be a Pandora’s box of unintended consequences. Consider for a moment the global effort that is required today to ensure our species doesn’t succumb to nuclear apocalypse. The desires to shorten World War II and gain a weaponry advantage drove the US to invent nuclear arms. But this short list of marginal gains (WWII would have inevitably drawn to a close without the bombings of Hiroshima or Nagasaki, and the US had only a four year “head start” as the Soviet Union developed the technology in 1949) is drastically outweighed by the incredibly lengthy list of costs resulting from having to fight nuclear proliferation ever since.
How much money and political maneuvering is required to keep nuclear arms out of the hands of “undesirable” nations and terrorist organizations today? Without the invention of nuclear weaponry Iran, Pakistan, North Korea and Al-Qaeda would represent only a fraction of the threat they currently do. If you could snap your fingers and make that technology disappear a huge chunk of US foreign policy spending would go with it. Instead, today, there are fears surrounding the global price of oil because international sanctions opposing the development of nuclear arms in Iran have caused that country to threaten closing access to the Strait of Hormuz in retaliation.
Anyone who thinks seriously about the political consequences of eugenics will quickly have a laundry list of potential dangers. Among the possibilities are a new social “class” with genetic advantages. To try and understand the political implications of such a class consider the rich human history of fighting over the distribution of wealth and power and then try to imagine what the reaction of a majority population might be if a small class of people thrive because they were implanted with superior DNA. Another serious problem would be a likely increase in average lifespans which would drive the global population upwards and add pressure to a planet which is already incapable of meeting resource demands.
An effort must be made to avoid these science-fiction scenarios, which is going to require an international push towards the anti-proliferation of eugenics. The UK has led this charge by strictly regulating genetic selection to only serious, inherited disorders. It is imperative that the rest of the world follow. While arguments will surely be made that any such efforts are a waste of time, that the proliferation of this technology is inevitable, and that there is a moral obligation to keep it in the “right hands”, our experience with nuclear weapons proves this thinking to be folly. The victory of these arguments in the 1940s sealed the fate of any preemptive anti-proliferation campaign for nukes and did nothing but accelerate the process of getting that evil power into dangerous hands.
