There are so many important technology to keep our life  easier such a car, computer and so on. Among the technology, I think that a an electric power is the most important technology to us nowadays. Simply let’s think about what would be will happened to us without electric power right now ? I’m afraid that I just think about the result without EP in the world. From tiny things such as no lights, no traffic sign on the street to no running almost factory and power plant, as I know even the water at the restroom is worked working by because EP with water pump. In the end, we must probably get back to the primitive age. When I want fire, I have to gather branch of tree or something burning easily. And rubbing some two materials to make heat enough to burn the branch. Additionally after we consume the all processed food in stock in market, we need to go river, sea, or mountains to get a something such as fish and fruits. What is different this situation with the primitive person doing before?
