Abstract
The first part of the article discusses the natural environment of humans and its evolution over the past centuries. It examines the changes that have occurred in just the last 100 years and how they have impacted human habitats. It explores how architects and engineers shaping our settlements have influenced the environment, as well as how the model developed during economic growth affects and presents challenges to our society, particularly regarding the interconnection between climate change and the development of our cities.
The second part of the writing addresses the issue of megacities, exploring where the almost endless growth of our metropolises has led, the problems it causes, the differences observed between the growth of megacities in developed and developing countries, the reasons behind it, and the additional difficulties it poses to their residents.
