“Biological warfare is the intentional use of disease-causing microorganisms or other entities that can replicate themselves (e.g., viruses, infectious nucleic acids and prions ) against humans, animals or plants for hostile purposes. It may also involve the use of toxins: poisonous substances produced by living organisms…plants…and animals. Biowarfare

Biowarfare:

Biowarfare 1) The organism, called _Bacillus Anthracis ,_ is grown in the lab. 2) Removed from a nutrient-rich environment, the bacteria turns into spores, which naturally clump together. 3) Spores are purified, separated, and concentrated. 4) Spores are combined with fine dust particles to maintain separation and increase time they can suspend in the air. 5) The powdery mixture is put into an envelope. 6) When released into the air, a high concentration of spores can be drawn deep into the lungs. The spores return to their bacteria state and a rapidly developing anthrax infection releases deadly toxins. (cnn.com)

PowerPoint Presentation:

Most people and nations agree that the use of biological or chemical weapons is unethical and morally wrong. So why are such weapons produced? One significant reason is that most biotechnology is dual-use, that is, it has both peaceful and harmful purposes. The same technology that gives us genetically engineered medicine can also give us military weapons. Biowarfare
