Using gene editing to enhance the aggressiveness of certain animals for military purposes may be feasible in theory, but in practice it involves many complex ethical, legal, technical and practical challenges. Here are some aspects to consider: 1. **Ethical issues**: - **Animal welfare**: Deliberately enhancing the aggressiveness of animals may cause them to suffer unnecessary pain and stress, violating the basic principles of animal welfare. - **Moral responsibility**: Humans have a responsibility to treat animals humanely and responsibly, and changing their behavior for military purposes may raise serious ethical controversies. 2. **Laws and international treaties**: - **Biological Weapons Convention (BWC)**: The international community generally prohibits the development and use of biological weapons, including the use of biotechnology to enhance the behavior of animals as weapons. - **Animal protection laws**: Many countries have laws to protect animals from cruelty or inhumane treatment, and genetic modification to enhance aggression may violate these laws. 3. **Technical challenges**: - **Complexity of gene editing**: Aggressive behavior is affected by multiple genes and environmental factors, and it is difficult to precisely control it through gene editing alone. - **Unpredictability**: Genetic modification may lead to unexpected side effects, affecting the overall health and behavior of animals, making it difficult to ensure their reliability and controllability in military operations. 4. **Practical operational issues**: - **Control and management**: Even if the aggressiveness of animals is successfully enhanced, how to effectively control and command these animals in a complex battlefield environment is also a huge challenge. - **Logistics support**: A lot of resources are needed to breed, train and maintain these genetically modified animals, increasing the complexity and cost of military operations. 5. **Social and environmental impact**: - **Public opposition**: The public and the international community may strongly oppose such behavior, leading to political pressure and reputation risks. - **Ecological risks**: Genetically modified animals may have unpredictable effects on ecosystems and disrupt ecological balance. In summary, although gene editing technology has made significant progress in recent years, using it to enhance the aggressiveness of animals for military purposes not only poses major technical challenges, but also faces many obstacles at the ethical, legal and social levels. Therefore, this application is not realistic at present and does not meet the basic requirements of modern society for science and technology ethics and law.
