What does it take for millions of people to live in the same place? From sprawling megacities built on tiny islands to urban giants surrounded by mountains, deserts, rivers, and floodplains, the world’s most populated cities exist in some of the most challenging geographic environments on Earth. In this video, we explore the extreme geography behind the world’s most populated cities and uncover how terrain, climate, coastlines, rivers, natural resources, and sheer human ingenuity have allowed these cities to grow into enormous urban centers. From Tokyo and Delhi to Shanghai, Dhaka, Mumbai, São Paulo, and beyond, these cities reveal just how dramatically geography can shape where and how humanity lives. #Geography #Megacities
