According to Title 18 USC 2332a(c)(2)(c), how is a biological WMD defined?

The definition of a biological weapon of mass destruction (WMD) under Title 18 USC 2332a(c)(2)(C) specifically focuses on weapons that utilize biological agents. Biological agents are microorganisms or toxins that can cause harm or death to living organisms. This includes bacteria, viruses, fungi, or even biological toxins, all of which can result in widespread harm to human health, agriculture, or ecosystems.

The rationale behind this definition underscores the potential of these agents to inflict massive casualties and disrupt societal functions, making them distinct from other forms of weapons, such as chemical or radiological agents. The emphasis on biological agents reflects the significant threat they pose and the unique considerations required when addressing their proliferation and use.

In contrast, the other definitions mentioned in the choices do not align with the specific language and intent of the statute regarding biological weapons. They reference other types of weapons, such as those based on radioactive materials, explosive chemicals, or those causing environmental damage, which do not fall under the classification of biological weapons of mass destruction as outlined in the law. Thus, the focus on biological agents makes the correct answer specifically pertinent to the legal definition being asked about.
