Review Questions

• How does biotechnology enhance agricultural productivity and what are its implications for food security?
  • Biotechnology enhances agricultural productivity through genetic modification techniques that create crops with improved traits such as pest resistance and drought tolerance. This can significantly increase yield per acre, which is crucial for feeding a growing global population. The implications for food security are profound as these innovations can help stabilize food supplies and reduce reliance on chemical pesticides, ultimately contributing to more sustainable agricultural practices.
• Evaluate the impact of biotechnology on healthcare and its potential to transform treatment methods for diseases.
  • Biotechnology has revolutionized healthcare by enabling the development of targeted therapies and biologics that address specific diseases at a molecular level. For instance, biotechnology allows for the production of monoclonal antibodies that treat various cancers. The potential to transform treatment methods lies in personalized medicine approaches that consider individual genetic profiles, leading to more effective therapies with fewer side effects.
• Critically assess the ethical challenges posed by biotechnological advancements in agriculture and medicine, particularly regarding accessibility and biodiversity.
  • The ethical challenges posed by biotechnological advancements include concerns over accessibility, as not all populations may benefit equally from these innovations due to cost or availability. Additionally, there are worries about biodiversity loss resulting from monoculture practices associated with genetically modified crops. The debate over whether these technologies should be broadly implemented or regulated highlights the need for responsible governance that balances innovation with ethical considerations to ensure equitable access and environmental protection.
