Chemical/biological warfare is the term used to describe the use of chemical or biological agents as weapons to injure or kill humans, livestock, or plants. Chemical weapons are devices that use chemicals to inflict death or injury; biological weapons use pathogens or organisms that cause disease. Pathogens include bacteria, viruses, fungi, and toxins (poisons produced by animals or plants).
