by Over the course of world history, countless wars have taken place over land, resources, power, and other conflicts such as political ideas. While the reasons behind wars that have taken place are relatively consistent, one aspect of war that has changed dramatically is the science and technology that is involved in war. In the early wars of our history, soldiers fought with swords, shields, bow and arrows, and generally fought alongside each other in open-land. These soldiers were not extremely equipped to defend themselves in open-land, resulting in many casualties. As technology and science in our world advanced, new methods of fighting wars were introduced. In World War I which began in 1914, technological advancements were noticed as there was widespread use of telegraphs, telephones, armored automobiles and tanks, as well as aircrafts and machine guns. Chemical weapons such as chlorine, mustard gas, and phosgene were also utilized in WWI. These technologies were new at the time and proved to be very effective in war, however, resulted in many casualties among civilians. In World War I alone, with the use of these new technologies and chemical weapons, 16 million people were killed. Technology and science became so important during the twentieth century that nations organized scientists and engineers for the purpose of war efforts. In World War II, science and technology in war continued to advance as nations prepared in the most advanced way possible to protect their power in the event of an attack. The atomic bomb, for example, was created in 1938 in Berlin, Germany by nuclear physicists. This led to the American-led effort to develop a functional atomic bomb known as the Manhattan Project. At the end of 1942, US president Roosevelt authorized the formation of the Manhattan Project, gathering many scientists and military officials to work on nuclear research in response to the fear that German scientists had been working on a nuclear weapon since the 1930s. The United States used the atomic bomb twice against Japan at the end of World War II, once in Hiroshima and once in Nagasaki. The atomic bomb is extremely dangerous as it can kill tens of thousands of people instantly, and many more from radiation exposure over a few days. In World War II, over 60 million people were killed. While the advancement of technology and science has proved to be extremely effective in war efforts, it also has resulted in millions of casualties due to the increased amount of damage that these new weapons can conduct. While nations compete to have superior weapons, there has been a race between all nations of the world to develop the most advanced and destructive technological and chemical weapons in order to protect themselves from other nations. While many high powered technological weapons have not been utilized in war due to the amount of destruction they can result in, extremely high powered weapons exist as a result of the race to have the best technology and science in war. As this advancement continues, I believe that people across the world should be in fear of the destructive potential of many high powered weapons that exist as a result of technological and scientific advancement. If no line is drawn regarding how destructive these weapons can become, many individuals fear the event of another world war where an extremely large portion of our world population can be wiped out in seconds. I do not believe that there is a way to stop nations from advancing further in war technologies and sciences, however I think that if this advancement continues much further that there is potential for mass destruction that goes far beyond what occurred in Japan with the use of the atomic bomb.
