Biotechnology played an important role in solving real-world problems in agriculture, medicine, and environmental science. It helped improve crop production, develop new treatments for diseases, and clean up pollution. This review aimed to explore the uses of biotechnology in these three fields and show how they were connected. To achieve this, the researcher used a scoping review method following the PRISMA 2020 guidelines. A total of 32 peer-reviewed studies from 2020 to 2025 were selected using the inclusion criteria: full-text availability, recency, and relevance to biotechnology in agriculture, medicine, or environmental science. The findings showed that biotechnology helped farmers grow more food using gene editing tools like CRISPR. In medicine, it supported the creation of vaccines, cancer treatments, and faster disease detection. In the environment, it helped reduce pollution through bioremediation and other natural solutions. Many of these breakthroughs used similar tools and shared goals of sustainability and health improvement. In conclusion, biotechnology was a powerful tool with wide-reaching benefits. However, challenges such as ethical concerns, safety issues, and unequal access still needed to be addressed. Future studies should promote responsible and inclusive use of biotechnology to create a better future for all.
