Chemical and Biological Warfare essays

Chemical and Biological Warfare essays Chemical warfare is the use of natural or synthetic substances to disable or kill an enemy. It is also used to prevent them from using resources such as agricultural products or foliage in which to hide. Why use chemical weapons? Because of their ability to cause mass casualties or damage to an enemy with only a limited amount of risk to the forces who are using the chemicals. The origins of chemical warfare dates back to the time when humans began to use weapons. Primitive people used poisonous darts and arrows to hunt for food and in battles between tribes. Thousands of years later people still use these inhumane and deadly weapons with pretty much the same intentions primitive men did. The first time chemicals were used in war against the United States was during World War I. American soldiers were not at all prepared for chemical warfare. Nerve agents and mustard gas were used in this war. After the end of the war, a treaty was signed in Geneva on 1925 by many nations to prohibit every nation who signed it: the use of any asphyxiating, poisonous, or other gases and bacteriological methods of warfare. This treaty came to be known as the Geneva Protocol. However this protocol did not prohibit the production of these agents. Despite this agreement the United States, the Soviet Union and other countries kept producing and stocking piles of chemical weapons. They also improved their protection against these agents. Because having a better offense obviously implies having a better defense. In 1969, the United States stopped the production of all chemical weapons. They also began to destroy those munitions that had been stocked for many years. But in 1987, they began once again to produce those weapons with a better method of storage: they filled the canisters with two comparatively harmless gases which combine to form deadly gases only after being released fro...

Scientific method to an everyday problem - Essay Example ’s watch might have slipped, falling on the sidewalk of the park when he attempted to get something out of his pocket which escaped our notice; (2) The watch could have, in the similar manner, fallen off Aunt Susie’s place due to Jay’s unconscious habit and I particularly recall that he stayed outside of the house so I could not see what exactly occurred on his spot while I talked to my aunt for a few moments in the living room; (3) It could have gone lost in the cinema place, perhaps on the carpeted area which muffled fallen objects from obvious hearing. Experimentations Performed: Since our distance then was still closer to the mall than to our residences, we hurried our way back in and asked a security officer on duty to help us search the paths we remembered having walked on. It took about twenty minutes and it had been a thorough effort for the three of us. Then we returned to Aunt Susie’s house for the same intention. Results: Jay’s watch did not get lost in the theatre because Aunt Susie confessed she had it when a boy of 10 came buzzing at the gate a few minutes after we left her house and the boy handed her the watch. She was further told of the metal-clicking sound from Jay’s pocket. Conclusion: The 10 year-old boy was rushing to catch up with us after witnessing Jay’s watch lay on the grassy ground of the park he was playing at, assuring himself that one of us is the rightful owner for we were hardly a meter away from the scene where the watch was. Second Example – Moreover, I have also encountered scientific method as applied to the case of my cousin who complains of heavy traffic on his way to work on Thursday mornings prior to rush hour and this he observes to have taken place in three consecutive weeks.
