g the world's greatest hazard.
             Thousands of microbial pathogens and toxic occur in nature, only very few of them are qualified as biological weapons.3 Biological agents that are considered suitable to be turned into biological weapons share some common characteristics and features.1 They have the ability to infect reliably in small amounts.3 High amount of these weapons can cause illnesses that usually result death and incapacitation.4 They have the ability to remain strong and powerful during production, storage, and handling.3 It takes a short time for these weapons to incubate and develop after infection.2 Many of these substances are very hard to cure and are very resistant to medical treatment.4 They are inexpensive and are easy to be produced in large numbers.2 They survive easily in the natural environment.3
             Biological weapons can dispense, project, or disseminate disease causing and toxic agents for use in warfare and terrorism.4 These weapons may take in form of missile warhead, aerial bombs, or spray devices.2 Biological weapons primarily function by inhalation, infecting open wounds, or contaminating food and water supplies.5 Because the purpose of biological weapons is to make huge amounts of people ill and do not necessary have to destroy properties, biological would be more accurately termed "mass casualty weapons" rather than "weapons of mass destruction".3
             Modern bioengineering techniques can be used to enhance and upgrade existing biological agents and make them into ideal biological weapons.3 Biological weapons should be considered strategic and tactical weapons because they have the ability to inflict immense damages over a wide area.4 Biological weapons have a delayed effect, which make them very useful for terrorists: a time lag between dispense and appearance of symptom.2
             Even though biological weapons have a very long history, they were not widely and commonly used in the ancie...
