トピックは"Has urbanization had a positive effect on Japanese society?"で、ポイントはconvenience、economic effects、health、human relations、the environment、traditional cultureの6つ。私は最初の3つを使って賛成側の意見を書いたよ。
There are people who express a harsh objection to urbanization. They cite some negative aspects of urbanization to validate their claim. Weighing the advantages and disadvantages of urbanization, however, merits that urbanization has brought to Japanese society far outweigh its disadvantages. I would like to write about the three benefits of urbanization.
Firstly, urbanization has made our lives significantly convenient. For instance, there are dozens of convenience stores within walking distance if you are living in an urbanized city center, meaning that you can get your hands on daily necessities round the clock. You also have an easy access to train traffic and you can freely move across the city while saving the cost for gasoline.
Secondly, urbanization has improved the health of citizens. Thanks to the adequate infrastructure and streamlined communication, people who show worrisome symptoms can be delivered to a hospital within a matter of minutes. On top of that, they can receive high-quality treatment and medication because medical institutions in urban areas are usually well-funded and are equipped with state-of-the-art medical devices.
Thirdly, economic effects of urbanization cannot be ignored. Large-scale transaction and business operations were made possible only after urbanization was fully completed. Headquarters of multinational companies are situated in busy city centers, attracting customers and huge investments from all over the world.
In conclusion, urbanization has brought tremendous benefits to Japanese society and the possible negative impacts of urbanization pale in comparison to its advantages.
