This book contains geographic analysis of regions and attributes
with specific regard as to how they fit into the man-land
relationship. Through looking at these features, Vidal attempts to
portray each region as an example of the unity of man and land
which is called environment. In considering population, raw
materials, cultural development, pattes of settlement, and
transportation, we see both the interconnectedness of environmental
factors and how that relationship is cashed out in terms of
possibilism.
