This resource paper on the interrelations between man and the environment is part of a series designed to supplement undergraduate geography courses. It outlines an approach to man-environment problems. Chapter one describes how an environmental perspective relates to the study of human geography. Chapter two describes the main transactions between man and the environment. Under consideration are the adaptive relationships between the environment and individual human beings, human groups, technology, and language. Chapter three relates man's distribution and economic activities to the functioning of the natural and modified ecosystems of the earth. The authors conclude that a nonexploitive relationship between man and the environment can be achieved only when we have discovered a system of management sophisticated enough to cope with the accelerated pace of technological innovation.
