i disagree because big cities are mostly where big and tall buildings are built to provide work place for adults with different personalities. I also believe that big cities are mostly stuffed with high rate of mobility and it will make them think like time changes rapidly, which eventually will affect their mental health. In my country, big cities are the centre of activity, industry, and all that honestly can cause the environment to be harmful for people who are still growing up. High rate of transportation mobility leads to bad air quality, especially if the city is not providing any prevention forms for that. I think adolescences will fit more to live outside big cities and look out for more environment that helps them to grow healthily.
