雅思写作 Task 2

As global urbanization accelerates, more and more people are choosing to relocate to large cities in search of better opportunities. However, the continuous rise in urban population density has also triggered issues such as housing shortages, traffic congestion, and environmental degradation. In addressing these challenges, some argue that resources should be prioritized for improving existing urban infrastructure, while others advocate for policy levers to encourage population dispersal toward small and medium-sized cities. Which strategy do you believe is more effective in ensuring the sustainable development of future cities? Please elaborate on your stance, providing reasons and concrete examples to support your viewpoint.
