What is one possible ethical concern surrounding gene therapy?

One significant ethical concern surrounding gene therapy is the modification of physical traits for cosmetic reasons. This practice raises questions about the morality and implications of altering human characteristics beyond necessary medical treatments. It introduces a debate about the potential for eugenics, where certain traits could be favored over others, leading to societal pressures or standards regarding beauty, intelligence, or physical abilities. Additionally, such modifications could widen social inequalities, as access to cosmetic gene therapies may not be available to everyone. The ethical implications extend to considerations of consent, especially regarding future generations who may inherit these modifications without having a say in the decision-making process. Thus, the concern is not just about the act of altering genes, but about the broader societal impacts and moral responsibilities that come with such advancements.
