Nuclear energy: A double-edged sword

Ever since the genius scientist Einstein put forward the famous equation E=mc^2, which shows the relationship between mass and energy, we are given the chance to embrace a totally new generation which can provide us with infinite energy at a cost of almost nothing. However, the recent tragedy happened at the Tokaimura nuclear station in Japan reminds us that this technology is indeed a double-edged sword.
Although it is not so often to see such nuclear accident, but there were several ones in the history, most of which resulted in severe situations. The one happened in Chernoby in the former Soviet Union on April 26th, 1986, was the most serious one, 56 people killed directly and thousands died because of the exposure to the radiation leak in the following years. Even the most advanced country like America could not escape from such accident. On march 28th, 1979, the three mile island generating station in US had a sudden leak of radiation, forcing 200,000 people to leave their homes. Admit it or not, the risk of using nuclear energy is as high as the benefit of it. Some people will argue that we have to use nuclear energy otherwise there will not be enough electricity especially for countries like japan that lacks natural resources. However, the point is that do we really need to consume so much energy? As the technology develops, our life keeps becoming more and more automatic, demanding more and more energy. But do we have to live that way? As one of all kinds of living creatures, should not we live more naturally rather than evolving into a kind of indoor monster? Technology is also an double-edged sword, and the nuclear station is one of the best examples that always remains us in a painful way.
