Biological warfare involves the use of harmful microorganisms, such as bacteria, viruses, or toxins, to intentionally cause illness or death in humans, animals, or plants. This form of warfare can be deployed through various means, including aerosols, contaminated food, or water supplies, making it a covert and potentially devastating method of attack. Historically, biological agents have been used in conflicts, with notable examples including the use of anthrax and plague during wartime. The development and stockpiling of biological weapons are prohibited under the Biological Weapons Convention, which aims to prevent the use of these dangerous agents in warfare.
