Uncomfortable though it may be to consider, the rise and fall of societies is the ordinary course of history. Societies and their environments are subject to constant change. Transformations determine who we are, how we live today and how what our future development will look like.
The forces driving such transformations in the past as well as in the future are numerous, varied and complicated, operating as they do in the highly dynamic relationship created by interaction between human beings and their environment. Triggers include climate and environment, demography and social inequality mental worlds, the movement of people, animals and objects, or diet. Though transformations can appear under a variety of guises, one thing is certain: everything remains different.
