Then Krimsky pointed out that genetically modifying children

someone else may argue “if the
genes of the next generation could be chosen, we would have many more intelligent,
rational, and logical children”.
However, “revolution works at the margins, and it does so through
trade-offs”. (
KOZUBEK, 2017) For example, the infamous “APOE4 variant, the
single strongest risk variant for late-onset Alzheimer’s disease, remains at
15% frequency in the population—one reason is that it may also up Vitamin D.”(KOZUBEK, 2017) Overall, engineered
traits may advance the mankind in a temporary period, but
ultimately they may turn out to be detrimental. From a biological standpoint, decreased biodiversity
due to “baby designing” will impede the human ability
to adapt, which is quite dangerous considering the worsening environmental
conditions???1 . On the other side,  eugenics, an idea
worshiped by the Nazis holds the similar idea that selective breeding can be
used to improve the human race.( Parry,2013) Winston and Krimsky
pointed out that genetically modifying children via selecting desirable traits for
them evoked this approach. (Parry, 2013) In an international
level, What if some countries secretly launch an ambitious program to “improve
the quality” of its citizens? What if mutants with wings, flippers, gills were created
as a tool for the rich and those in power to dominate the
earth? Just as described by Hayes(2008): “In a world still barely able to contain the forces of
nationalism, ethnocentrism, and
militarism, the last thing we need to worry about is a high-tech eugenic arms race.”


Many people contended that Most of the babies’ genes are genetically altered because
they will die without the altering, AND We could have healthy babies free from
any diseases, removing genetic disorders,  deformities and giving them a longer
life expectancy. (,
2018)But, if this technology becomes a realistic and
accessible medical practice, it would create an even
wider disparity between those that can afford the service and those who cannot.
As the cost of sequencing one human genome dropping from over $100,000,000 in 2001 to
about $7,000 in 2013, a set of assisted reproductive technology including IVF (in vitro
fertilization), PGD (preimplantation genetic diagnosis) and CVS (chorionic
villus sampling) have
opened the door to parents seeking advantages for their children, in the
meanwhile, however, limited its use in the
poverty colony, which
will contribute an unfair condition for the underprivileged. (“Designer”,2017) Furthermore, the impecunious parents who cannot afford
the fees of the procedure are doomed to fail the preparation for their children
to compete with their counterparts who will seize the favorable position by
virtue of enhanced traits owing to advantageous genes their wealthy parents
“bought” them before birth. Just as is illustrated by the
science-fiction film Gattaca, which explores this issue by depicting a world
where only genetically-modified individuals can engage in the upper echelon of
society. The wealthy able to afford the selection of desirable
traits for their offspring and those of lower socioeconomic status unable
to afford the same option will ultimately divide to a segregation between the
superior “modified” humans, and the pure but inferior ones. And the “economic
divisions may grow into genetic divisions, with social distinctions delineating
enhanced individuals from unenhanced individuals”.( Ly, 2011) Therefore, if the usage of the
technology is not constrained properly, the social situation of inequality
between the rich and the poor will turn more serious.

Someone may argue that
genetic selection allows human beings to turn the tide on the congenital disease by granting them the power to remove
or transform the causing genes in human genome. However, even the examination
of genes related to certain traits may aggravate the discrimination toward the
“unfit” and the disabled, not to mention eliminate them. “The assumption that the genetically “unfit” ought to be prevented
from being born
embodies invites a profoundly denigrating
and worrisome attitude toward
those who do get to be born”.( President’s, 2003)
