There are a number of problems in the world, such as global warming, a population explosion, and environmental destruction. However, I believe that the world will remain as peaceful in the future as it is now for the following two reasons. Firstly, we can settle an international dispute using diplomacy. For example, the United Nations can help countries involved in a conflict to sign a peace treaty. Secondly, the development of information technology will enable countries to know each other better and to reduce misunderstandings. Most of the international disputes are caused by misunderstandings, which is provoked by a lack of mutual knowledge. For the above two reasons, I believe that the world will remain as peaceful in the future as it is now.
