It is reasonable to argue that, at least to a certain extent, the physical and natural environment of an area influences the culture developing within it. On a pragmatic level, cultural factors ranging from apparel to the design of residences and commercial sites are greatly affected by climate and landscape. Commerce itself, which must powerfully shape the surrounding culture, is also profoundly linked to the environment, as in those societies evolving as agricultural or dependent on coastal activities. Then, and perhaps less overtly, the natural environment shapes the population as well. Certainly, history provides ample evidence that people from southern regions create cultures different from their northern counterparts, even within a shared country. Terrain and climate aside, there is no disputing that just where a country lies, and what geographic differences are within it, must profoundly effect how its culture develops.
