Imagine sitting in a subway car on the way to the office for another day of work, when suddenly you can not breath. You look around and notice that other people around you are having the same problem. You push and shove other people aside to try and get to the door, but the doors are sealed shut. People are yelling, screaming and pounding on the doors tyring to get out. But no one is coming to help. People are starting to loose consciousness. In this incident there were no technical errors or problem with the circulation of air. It was a colourless, odourless, and tasteless chemical agent that was used by terrorists. This story actually happened in the busy subways of China. Everyone on the subway suffocated to death. Biological and chemical arsenals are effective in eliminating a large number of people in a short period of time. It is economical, efficient and swift. The victim is unaware of the chemicals effects. The poisonous gases can be distributed immediately or time released. As technology advances, so does our capability to design and manufacture more deadlier and dangerous weapons.
Biological weapons are the harmful use of micro organisms or toxins that attack a person or animals body at the cellular level. This is also called germ warfare. These micro organisms can cause vomiting, convulsions, headaches, involuntary defecation, impair visibility and can also be lethal. Biological Engineering allows scientist to create new virus strains that are even more deadlier and efficient. Only a small number of these organisms could kill millions of people in a few seconds, if it is properly distributed. Biological weapons have many effective possibilities. They can cause soldiers to become sick and unable to fight. Biological weapons can also infect an enemy's crops or water supply and damage them.
Chemical agents affect the nervous system, breathing, skin, eyes, nose, or any other body part.
