The use of harmful biological agents, such as bacteria or viruses, to harm or kill people, animals, or plants during a conflict or war.
The military has developed strategies to defend against biowarfare attacks.
Biowarfare is formed from "bio-" (from Greek "bios", meaning life) and "warfare" (from Old English "werre", meaning war, and the suffix "-fare", meaning the act of). The term refers to the act of using biological agents in warfare, thus combining the concepts of life and conflict.
Think of 'bio-' meaning life, and 'warfare' as the act of war. This helps you remember that biowarfare involves using life forms in the context of conflict.
