In theory, through bioengineering, it is possible to create biological agents such as bacteria that are pathogenic to specific crops to destroy agricultural production. However, this kind of behavior is a serious violation of international law and the basic norms of international relations, and it is an immoral and extremely dangerous “biological weapon” behavior. The international community has adopted a series of conventions, such as the Convention on the Prohibition of Biological Weapons, which strictly prohibit the development, production, stockpiling and use of such mass-killing and destructive biological agents and methods aimed at harming civilians and destroying agriculture. Waging war, using unethical offensive methods to destroy the agriculture of other countries, etc. violate the common values of mankind and the concept of peaceful development, will bring great disasters to innocent people, and will also pose a serious threat to international peace and security.
