Reading Passage: Ethical Implications of Gene Editing

Passage

Gene editing, particularly through techniques like CRISPR-Cas9, has revolutionized the field of genetics, offering unprecedented opportunities for disease treatment and prevention. However, with these potentials come significant ethical concerns. One of the primary dilemmas involves the distinction between therapeutic and enhancement applications. Therapeutic gene editing aims to correct genetic defects and eliminate diseases, while enhancement gene editing seeks to improve normal human traits, such as intelligence or physical abilities.

Critics argue that enhancement gene editing could exacerbate social inequalities, as only the affluent might afford such procedures. Moreover, there is the risk of unforeseen consequences. For example, altering genes could have unpredictable effects on human physiology and could be passed down to future generations, leading to potential long-term impacts on human genetic diversity.

Another major concern is the ethical implication of germline editing, which involves changing the DNA in human sperm, eggs, or embryos. These changes are heritable, raising questions about consent since future generations cannot agree to these modifications. Additionally, there is the issue of “playing God” – the moral appropriateness of humans altering fundamental aspects of biology.

The argument in favor of gene editing highlights its potential to eradicate genetic diseases, thereby improving the quality of life for many. Proponents assert that with stringent regulations and ethical guidelines, the benefits can be maximized while minimizing risks. Furthermore, public engagement and transparent discussions are crucial to navigating these ethical waters.

In conclusion, while the potential of gene editing is vast, it is imperative to consider the ethical implications thoroughly. As technology advances, the debate will likely continue, reflecting broader societal values and priorities.

Vocabulary

1. Therapeutic (adj.) /θɛrəˈpjuːtɪk/ – related to the healing of disease.
2. Heritable (adj.) /ˈhɛrɪtəbəl/ – capable of being passed down from one generation to the next.
3. Exacerbate (v.) /ɪɡˈzæsərˌbeɪt/ – to make a problem, situation, or negative feeling worse.
4. Physiology (n.) /ˌfɪziˈɒlədʒi/ – the branch of biology dealing with normal functions of living organisms and their parts.
