Cars are the primary reason for car crashes. Airplanes are the main reason plane crashes occur. Coastlines are susceptible to tropical storms. Should we also move people away from the shores in the prospect of safety? Japan is an island nation that relies on nuclear power because the natural resources on its land aren't enough. Rather than abandoning such a crucial source of power, Japan should continue to develop safer plants. Many things on Earth are inherently dangerous, but they're equally necessary.
Japan should continue to utilize nuclear reactors because they are an excellent source of energy in a country with little natural resources and the benefits outweigh the consequences even in a nuclear meltdown. For example, before the earthquake, 10 million people directly benefited from the nuclear reactor. After the earthquake only a few died directly from the failed nuclear power plant. The death price is a cheap, temporary price to pay for the many years of fail-proof, sturdy service.
If there is one thing to be learned from the earthquake of March 11th, it's that nuclear power is not nearly as safe as we once thought that it was. There have been far too many accidents with regards to it over the years, and we need to find new energy sources.
An earthquake as strong as the one that occurred on March 11th 2011 is a strong signal that mother nature is a threat to the entire nation itself.
People within Japan have also learned that there is no such thing as a "fail-safe" design for the Nuclear Reactor designs. The biggest cliff-hanger is "Is it worth risking the lives of many innocent lives just for a good energy source for the nation?" Seems a bit unreasonable to me.
