Genetic Engineering for Disease Prevention and Treatment
One of the primary drivers behind genetic engineering is its potential to prevent or treat genetic diseases. Genetic disorders such as cystic fibrosis, Huntington’s disease, and certain types of cancers are directly linked to specific genes. By editing these genes, scientists hope to eliminate the underlying causes of these diseases. However, this approach also raises questions about what constitutes an acceptable use of genetic engineering.
Questions to Prompt Discussion:
- Should genetic engineering be used only for severe diseases, or should it also be available for less serious conditions?
- Do you think everyone should have equal access to genetic therapies, or should they be limited to certain groups?
- How might society address the potential disparity in access to genetic engineering for disease prevention?
- What criteria do you believe should determine which diseases are prioritized for genetic intervention?
The Ethics of Enhancing Human Traits
Genetic engineering could theoretically be used to enhance human abilities, including intelligence, physical strength, or even appearance. This possibility leads to ethical concerns, including whether it is right to alter human traits that do not pose a direct threat to health. This topic also touches on ideas about human identity, equality, and the implications of modifying traits that are often integral to personal and cultural identities.
Questions to Prompt Discussion:
- Should genetic engineering be limited to health-related issues, or should it also include enhancement of physical and cognitive traits?
