Scientists are responsible for the negative impact that are made by their discoveries Up to now, Scientists have made numerous contributions for the the peace of world and social development. They made a breakthrough for our world and found new technologies and discoveries which promote the innovation and to advance the social progress. But sometimes the new things discovered by scientists have the negative impact for society. A few people point out the scientists should take a responsibility for these negative impact. In my judgement, this is sheer nonsense. My reasons will be discussed blew. Firstly, government supports and subsidizes scientists to do research, sometimes demanding them. Scientists do not have decisive power on the vital items, what they do just obey the oder from government. Without the support from the government, scientists have little abilities to make a great discovery. It is not an individual behavior. Negative impact is not just scientist’s errors, on the contrary, the government should take the main responsibility for negative impact and outcomes. Illustrated with a simple example, the North Korean nuclear issue which ruins the peace of world, criticized by all over the countries. The study of nuclear power is not the individual desire of scientists, contrarily, which demand by North Korean’s government. In hence, there is on one censures the scientists, they would be more like to blame the North Korean’s government. Secondly, the new discovery is a double-edged sword, which has negative impact as well as positive impact. As the matter of fact, new discoveries bring the negative impact, in the meanwhile, it has taken a revolutionary change for our world, even the potential benefits we can not see clearly. Compared with the positive impact, the negative impact is not worth mentioning. People enjoy the change taken by great invention, appreciating all the great scientists. Scientists have no reason to take the responsibility for the negative impact. As the invention of car brings convenient and fast transportation which has changed our life style, it takes us the traffic jam and air population. Nevertheless, it is undeniable that we should give our thank to Henry Ford, who made the first car in the world. Similarly, as the nuclear power threatens the peace of world and human health, it is thought of as the clear and efficient power which can solve the shortage of fossil fuels.
