The documentary *A Generation That Changed the Earth* extends its lens to Dubai's Burj Khalifa and explores Mexico City's giant sewer system, discussing the largest man-made structures and the re-design of Earth by humans. To address the growing urban population and the limited availability of land, Hong Kong, China, has constructed a dense three-dimensional pedestrian walkway system; a company in southern China built a 30-story building in just three weeks. The documentary also narrates the rapid pace of change through the development history of aircraft models over the past 30 years. Statistical data in the film shows that in 1970, there were only two cities with a population exceeding 10 million worldwide, while in 2012, this number had risen to 27. The rapid growth is attributed to large-scale population migration. To maintain the operation of these large cities, numerous massive engineering projects are required. The documentary not only showcases the height and speed of these changes but also uncovers the truth behind the transformations by examining the life changes of the people interviewed in the film. In one episode, the story begins with an ordinary Hong Kong family, where the female head of the household is hesitant to buy more items due to a lack of storage space, and her daily journey involves navigating between buildings and overpasses, almost never touching the ground. When introducing the world's tallest building, Dubai's Burj Khalifa, the documentary begins with how the cleaning workers clean the 24,000 windows of this skyscraper. Additionally, the documentary will explore how to meet the survival needs of the 7 billion people on Earth: food, energy, and water. The camera will take viewers to the world's largest greenhouse, visit the largest artificial lake in the United States, Lake Mead, and introduce how the construction team of China's South-to-North Water Diversion Project built an artificial canal, comparable to a natural river, stretching 1,200 kilometers.
