Creating a bacterium through bioengineering to specifically destroy a specific crop will have a profound impact on the ecological environment and social ethics. This practice involves the development of biological weapons, which is prohibited under international law and multiple treaties (such as the Biological Weapons Convention). In addition, the use of targeted bacteria to attack specific crops may not only lead to unexpected ecological consequences, but may also affect related non-target plants and microbial communities, causing damage to agricultural and natural ecosystems. At the same time, such behavior may trigger international conflicts and sanctions, and damage the image and reputation of a country. Even from a scientific and technological perspective, such research needs to be strictly reviewed and regulated to ensure that it is safe, effective, and does not harm humans and the environment. Therefore, although there may be technical implementation methods in theory, it is extremely complex and undesirable in terms of ethics, law, and practical effects.
