Comprehension Passage
The field of genetic engineering has seen remarkable advancements in recent decades, with the development of technologies like CRISPR allowing scientists to edit genes with precision. While the potential for genetic engineering in medicine is immense, including the possibility of curing genetic diseases, it has also raised ethical concerns. One major debate revolves around the use of genetic engineering in human embryos. Proponents argue that editing genes to eliminate hereditary diseases could improve human health and longevity. However, critics warn of the risks associated with altering human DNA, including unintended consequences and the possibility of creating 'designer babies,' where genetic traits such as intelligence or physical appearance are selected based on personal preference. The long-term effects of these genetic modifications on future generations are unknown, leading to calls for stricter regulation and oversight in this area. The promise of genetic engineering is undeniable, but its ethical implications continue to spark heated debates worldwide.
What is one of the main ethical concerns related to genetic engineering in humans?
1
The elimination of all hereditary diseases.
2
The lack of potential medical benefits.
3
The potential for unintended consequences in future generations.
4
The immediate financial costs of genetic research.
