Projections of population growth are attempts to show how the human population statistics might change in the future. [ 1 ] These projections are an important input to forecasts of the population's impact on this planet and humanity's future well-being. [ 2 ] Models of population growth take trends in human development and apply projections ...
This increase has happened as the world's population moves towards the high (75–85%) urbanization levels of North America and Western Europe. Since the 2000s, the largest megacity has been the Greater Tokyo Area. The population of this urban agglomeration includes areas such as Yokohama and Kawasaki, and is estimated to be between 37 and 38 ...

This has brought a large change to environments as well as societies. [5] Urbanization transforms natural habitats to completely altered living spaces that sustain large human populations.
