Biological warfare
Biological warfare, also known as germ warfare, is the use of biological toxins or infectious agents such as bacteria (bacteriological warfare), viruses, insects, and fungi with the intent to kill, harm or incapacitate humans, animals or plants as an act of war. Biological weapons (often termed "bio-weapons", "biological threat agents", or "bio-agents") are living organisms or replicating entities (i.e. viruses, which are not universally considered "alive").
