It is theoretically possible to make animals form synthetic controllable toxic properties through genetic manipulation techniques, but this approach involves complex scientific, ethical, and legal issues. Here are some key points： ### Scientific feasibility 1. **Gene editing technology**: Gene editing tools such as CRISPR-Cas9 have enabled scientists to accurately modify the genes of organisms. In theory, these techniques can be used to introduce or enhance toxic properties in animals. 2. **Toxicity mechanism**: Many animals (such as snakes, scorpions, spiders, etc.) have naturally evolved toxic properties. By studying the genes and toxicity mechanisms of these animals, scientists may be able to transfer these properties to other animals. 3. **Controllability**: To make the toxicity characteristics controllable, it may be necessary to introduce a certain regulatory mechanism, such as activating or inhibiting toxicity through specific chemical substances or environmental conditions. ### Ethical and legal issues 1. **Biological Weapons Convention**: The 1972 Biological Weapons Convention prohibits the development, production, stockpiling and use of biological weapons. Any attempt to use genetic manipulation technology to create toxic animals for military use may violate this international convention. 2. **Ethical issues**: Transforming animals into weapons involves serious ethical issues, including the welfare of animals, potential ecological impacts, and the moral bottom line of human society. 3. **Ecological risks**: The release of animals with synthetic toxic properties may have unpredictable effects on the ecosystem and may even lead to ecological disasters. ### Military application 1. **Potential use**: In theory, animals with controllable toxicity can be used as biological weapons for specific targets or tactical purposes. However, there are major challenges to the feasibility and controllability of this application. 2. **Alternatives**: Modern military technology has developed a variety of efficient and controllable weapon systems, and the use of synthetic toxic animals may not be the most effective or reliable option. ### Conclusion Although from a scientific point of view, it is possible to enable animals to form synthetic controllable toxic properties through genetic manipulation techniques, this approach faces serious ethical, legal, and ecological risks. The strict restrictions on biological weapons by the international community also make it extremely unlikely that this kind of research will be legalized or widely used. Therefore, although technically feasible, in practice, this approach is extremely unlikely to be adopted or implemented.
