Review Questions

• How does CRISPR technology impact global health and agricultural practices?
  • CRISPR technology has a profound impact on global health by offering new avenues for treating genetic disorders through precise gene editing. In agriculture, it enables the development of crops that are resistant to diseases and pests, potentially increasing food security worldwide. By improving both health outcomes and agricultural productivity, CRISPR addresses pressing issues related to global sustainability and population growth.
• What are some ethical dilemmas associated with the use of CRISPR technology in human genetics?
  • The use of CRISPR technology in human genetics raises ethical dilemmas such as the possibility of creating 'designer babies' where parents could select for certain traits. This not only poses questions about equity and access but also risks unintended consequences in the gene pool. Additionally, the long-term effects of such modifications are uncertain, leading to concerns about safety and the moral implications of altering human evolution.
• Evaluate how different countries are responding to the challenges posed by CRISPR technology in terms of regulation and research.
  • Countries around the world are responding differently to the challenges posed by CRISPR technology. Some nations are establishing strict regulations to govern its use, emphasizing ethical guidelines and safety protocols to mitigate risks. Others are prioritizing research and development, seeking to position themselves as leaders in biotechnology. The variation in regulatory approaches reflects broader geopolitical interests and highlights the need for international cooperation in addressing ethical concerns while harnessing the benefits of this revolutionary technology.
