By the year 2080, the landscape of megacities has dramatically evolved, with urban centers in Asia, Africa, and South America dominating the list of the world’s largest cities. Lagos, Kinshasa, and Dhaka have surged past traditional giants like Tokyo and New York, each boasting populations exceeding 50 million due to rapid urbanization and high birth rates. Cities such as Mumbai and Jakarta have expanded vertically and horizontally, integrating advanced infrastructure to accommodate their swelling populations. Meanwhile, cities in Europe and North America, like London and Los Angeles, have seen slower growth or even population declines, reflecting aging demographics and stricter immigration policies. The histories of these megacities reveal a shift from industrial and economic hubs to centers grappling with climate adaptation, resource management, and technological integration. The megacities of 2080 are characterized by their resilience and adaptability, shaped by decades of migration, economic shifts, and the relentless push for sustainable urban living.
