Helpful Gene Mutation #4

My term paper in English two persuades that gene mutation is a harmful thing for humans because it damages genes through the chemicals in the environment and food-intake, transposable elements and malignant viruses. So, I'm gonna talk about what happened in Japan specifically in the Fukushima Prefecture.
The aberration in the nuclear power plant in Japan caused panic in the Philippines. It's because the radioactivity of the nuclear power plant is very high that it could cause mutation in our genes. But then, biologists said that the radioactivity could not travel as far as Philippines. Therefore, there is no reason why Filipinos should worry.
For the Japanese people, they are in a great difficulty because their food and water are contaminated. This contamination  may cause mutation because the ions which have high radioactivity will be taken by the people. That's why the Japanese are always checking their food and water nowadays.
