Nevertheless, I strongly believe that maintaining the current educational system would contribute to the prevention of accidents in the future. To be specific, our society is changing constantly without the awareness of its repercussions. This trend might outbreak cause some serious natural calamities such as global warming. In short, in order to tackle this phenomenon, we are able to use our legacy from the past. By using and interpreting them, we can predict some unexpected natural disasters. Furthermore, it is such a great chance to do self-examination ourselves. Some of the tragedies which happened in the past like World War would take place in contemporary era again due to the greediness of mankind. Hence, And we can could avoid those negative repercussions, if we are able to use the knowledge from ancestors properly.

In conclusion, there are convincing arguments both for and against learning a history in our school curriculum. But, I am convinced that the advantages of learning history outweighs its drawbacks, most especially when we give more concern about to our lives.
