Environmental Determinism is a theory that suggests the physical environment, particularly climate and geography, shapes human behavior and societal development. It posits that certain environments can lead to specific cultural and social outcomes, influencing everything from economic activities to social structures. This concept has been used to explain why some regions develop more rapidly than others. For example, areas with fertile land and favorable climates, like the Nile River Valley, may foster agricultural societies, while harsher environments, such as deserts, can limit development and lead to different social adaptations.
