The relentless tide of urbanization draws millions to cities in search of better economic opportunities and amenities. While cities are engines of innovation and growth, this rapid concentration of population strains infrastructure and resources. Overcrowding, traffic congestion, housing shortages, and increased pollution are common byproducts. Sustainable urban planning is critical to manage this growth. This involves investing in efficient public transportation, creating green spaces, and developing affordable housing to ensure that cities remain livable and inclusive for all their inhabitants.
