The simple mathematical concepts in the model and lack of input from social science in the development of the conclusions doomed the model to miscalculations. The entire discipline of geography is focused on this question. The subsequent sections of the course will also further inform students of the intricate and every changing relationship between the environment at several scales and the residents of Earth. The most superficial glance and a world map of human population reveals the fundamental fact that the human population is not uniformly distributed over the surface of the earth. The factors affecting the distribution are quintessentially geographic.
Some factors are place-based while others have more to do with connections among places.
All settlements are in some way connected to the availability of resources or access to ways of making a living. It is important not to over-simplify explanations for the distribution of population. One cannot say this pace is too hot, too cold, too wet, or too dry because it seems that it is always possible to find a place to prove the counter point. However we do see broad patterns, for example, the Poles are devoid of human population although small groups do make their homes on the arctic fringe. Other places seem to be too dry but where humans practice irrigation it is possible to find large numbers of people.
