This interesting book examines how human migration and settlement has affected planet Earth. From the earliest times humans have shaped and changed the landscape. The book will provides many historical and modern-day examples of changes to our planet caused by migration and settlement. As people need more land for farming and to build towns and cities, natural habitats and wilderness areas are destroyed. In countries such as India and China the urbanization of the population and the rapid growth of cities is creating pollution problems and adding to the problem of carbon emissions that are causing climate change. The growth of transport infrastructure between our "settlements" has made the daily migration of commuting easier, another contributor to increasing carbon emissions.
