"Robert Clark delves into 100 millennia of human history to create a unified and consistent explanation for humankind's need to spread itself across the globe. Examining events from different eras, Clark melds them together to form a framework for understanding the process of globalization.

Drawing from a variety of academic disciplines, the book reveals the spread of humans and their cultures to be part of an ongoing struggle to supply the needs of an increasingly large and complex society."--BOOK JACKET.
