The global population has reached a remarkable milestone, exceeding 8 billion people. According to United Nations estimates, the world’s population is projected to increase by nearly 2 billion by 2050, with a potential peak of 10.4 billion around the mid-2080s. This surge in population growth is driven by several key factors, including advancements in healthcare, improved living standards, and greater access to clean water and sanitation. With declining mortality rates, especially among infants and young children, and an aging global population, cities are becoming more densely populated than ever before.
