During
the last three decades, since the handling of genetic material
(molecular cloning) was made possible, hundreds of new
questions arose regarding on how ethical it is, and how human
it would be.
Every
new advancement in science and medicine is accompanied by
heavy skepticism, however in this case is different. Cloning
humans is a dream that statesmen and scientists had since a
long time to create the "perfect
human race"
immune to every disease and strong to battle any enemy.
Science fiction contributed to fuel the imagination creating
omnipotent monsters of the universe.
The
truth is that molecular cloning is being developed as a tool
to improve human health and to ease suffering. If that tool is
in the wrong hands, everything can happen as a knife in the
hands of a criminal.
The
ability of scientists to cure diseases by gene therapy is
still experimental, and every day more and more advances are
done to achieve that goal. Diseases like diabetes and cancer
are at the top of the list. People must be aware that the
replacement of a single gene will not always cure the
underlying cause of the disease and much more has to be done
in the study of molecular regulation of DNA.
The
step further in future medicine is the use of cells derived
from human embryos for the treatment of human diseases, since
animal embryos are not a viable option, and the last but not
the least, cloning humans themselves from somatic cells. Here
we have the bigger and stronger dilemma.
Now
let's analyze the ethics of these procedures. The use of
engineered genes to be inserted in human cells to cure
diseases is a project with an incredible potential, but the
task is hard to achieve yet. In this process if human
suffering is diminished and no harm is done to other people,
it cannot be considered ethically unacceptable. However, it
can be considered unacceptable from the religious perspective.
The unacceptability comes from the fact that genetic material
is the footprint of the human being itself and handling that
material to alter the genetic structure of an individual
regardless of the fact that a disease can be cured may be like
trying to play God. Those same questions came into place when
blood transfusions started almost a century ago. Christian
religions may be deeply involved in this kind of debate, since
changing the "status
quo"
can inflict harm to the basic principles in the religion
itself and the holiness of the human body. Nevertheless
surgery is widely accepted, as well as pharmacological therapy
both changing the function or the structure of the human
being.
The
leading concerns today are human cloning and handling of human
embryos for experimentation and therapy. Regarding human
cloning, we must revisit the possible purpose of the procedure
as reproduction, or perpetuation of certain individuals. The
concern raised on handling of human embryos relies on the
ethical and biological consideration of when an embryo becomes
a human being.
Cloning
procedures are very primitive themselves to be considered
serious enough for true reproductive purpose. The use of fully
differentiated cells to create a new individual is very
dangerous since the genetic material is already "processed"
and "aged"
and do not have the true potential of expressing itself into a
healthy human being. The telomeric length (size of the arm of
a chromosome) is shortened by the natural ageing process
generating copies of genetic material somehow defective. The
problem in this case is that the human individual created by
cloning, if born alive, does not have the potential of being a
truly healthy one and the lifespan and aging process is very
questionable creating unnecessary suffering; this is not
ethical from any point of view, either religious or agnostic.
The
use of human embryos is also ethically challenged. As stated
before, there will be several positions regarding when the
embryo becomes a human being. From the medical point of view
the use of human embryos to cure diseases once incurable is of
immeasurable potential. Having a tool to generate cells that
can become highly specialized in an individual to restore lost
function is almost like "magical".
Now if the question of when the embryo becomes a human is
politically answered, then regulatory agencies worldwide will
approve the technology and generate a regulation to
standardize the procedure. However from the religious point of
view, Christians consider a human being at conception (when
the first single cell is formed - the egg cell). From the
Christian point of view the use of human embryos for either
experimental or medical purposes is at the same level as
abortion.
Banning
human cloning or use of human embryos will not solve the
dilemma but only cover the eyes of common people to the
reality to come one day if science achieves its purpose.
Regulating
and enforcing the ethical use of human DNA for medical
purposes only will not only curb unscrupulous plans but help
humans be more humans.
In
this entire dilemma, ethicists, religious heads and
politicians have to come to some level of compromise, since
banning questionable ethical procedures may impair the
possibility to advance in medicine allowing unethical groups
to advance and profit from human misery.
Another
open question is how far from moral and ethical is the human
behavior presently, and what is the church doing to teach
Christian lectures and governments to enforce laws. Many
infectious diseases and cancers are behavioral/environmental
diseases that could be avoided and prevented with proper
teaching and enforcing of laws and regulations already in
place.
At
the end of these thoughts there is a philosophical question on
the human being in this world. Creating diseases and then
cures will only produce more diseases to be cured, endlessly.
Allowing more knowledge will spare the humanity from
unnecessary suffering.
