Review Questions

• How does biotechnology contribute to sustainable agricultural practices?
  • Biotechnology contributes to sustainable agricultural practices by enabling the development of genetically modified crops that require fewer chemical inputs, such as pesticides and fertilizers. These crops can be engineered for pest resistance or improved nutrient use efficiency, which helps reduce environmental impact while maintaining high yields. By minimizing chemical use and promoting healthier soil ecosystems, biotechnology supports sustainable farming methods that can help feed a growing global population.
• Discuss the potential environmental benefits and risks associated with bioremediation as a biotechnological solution.
  • Bioremediation offers several environmental benefits by utilizing microorganisms to degrade pollutants in contaminated sites, thus restoring ecosystem health. This process can be cost-effective and less disruptive than traditional cleanup methods. However, it also poses risks, such as the possibility of unintended consequences from introducing non-native microbes or creating toxic byproducts during degradation. Proper assessment and monitoring are essential to ensure that bioremediation efforts do not adversely affect local ecosystems.
• Evaluate the role of CRISPR technology in shaping future advancements in biotechnology and its broader implications for society.
  • CRISPR technology is reshaping advancements in biotechnology by providing a precise and efficient means of editing genes, which opens up possibilities for new therapies in genetic disorders and improved crop varieties. Its ease of use could accelerate research and development across multiple fields. However, this raises ethical concerns regarding genetic modifications in humans and potential ecological impacts when applied in agriculture. Society must navigate these implications carefully to balance innovation with responsible stewardship of biotechnology's capabilities.
