How
Far Should We Go?
There
are two ways to look at the ethical dilemmas posed by this new genetic
world. One is to say that genetic manipulation of humans is something
our species has been doing for millennia; it was old news when Romeo
and Juliet were star cross'd. Fathers have arranged marriages; societies
have placed strong taboos on breeding between relatives. In the
end, how is customizing your child's genetic makeup any different
than, say, piano lessons? And since when has it been wrong to want
the best for your kids?
Still, the counter-argument has a more visceral point. There is
something more than a little unsavory about all this mucking around
at the cellular level, especially when we don't wholly know what
the consequences of our actions will be. And while taking risks
with genetically engineered potatoes is one thing, risking moppets
is another.
Ultimately, what makes everyone a squeamish is that genetic screening
and manipulation often comes down to abortion. And nowhere does
our discomfort with all of this collide more forcefully than in
the very small arena of stem cells, cells from the very dawn of
an organism's life found only in embryos. At this point, each cell
can become anything -- skin, bone, blood -- but during gestation
they irrevocably change into the 210 types of cells that make up
the human body. In theory you could grow a whole new heart from
stem cells, new skin, new insulin-producing cells. A cure for diabetes
sounds great, except that a good number of people see "harvesting
stem cells" from embryos for research as just a fancy term for abortion.
Federal funding for fetal tissue research is currently banned; the
issue will be the subject of some emotional congressional debate
this summer.
Then there are the worries about privacy issues stemming from the
vast DNA bank being set up by the FBI. Not to mention the fear that
your genetic information could potentially be used to deny you a
job or health care. And the question of just who (if anyone) owns
the genetic sequences currently being mapped is still very much
up in the air, meaning that it's conceivable that someone could
someday collect royalties on your child's pale blue eyes.
