In theory, it is possible to create biological products that can be used for military purposes through genetic engineering, but this is extremely dangerous and violates ethics and international conventions. Genetic engineering technology can perform targeted transformation and editing of biological genes. If this technology is maliciously used, it is possible to design organisms that can produce substances of military use (such as new toxins, high-efficiency killer chemicals, etc.). However, this kind of behavior seriously violates the basic moral norms and ethical norms of mankind, and will cause immeasurable disasters and threats to human life and the entire ecological environment. The international community has adopted a series of conventions and norms to strictly restrict and prohibit such malicious use of biotechnology in order to maintain global peace, security and stability.
