Abstract
Unceasing technological advance is culturally defined as advantageous, but sociologists need to see it in ecological terms. Duncan's P.O.E.T notation heightens contrast between Ogburn's view of technology as a new environment and Park's attention to technologically extended people. Technologically colossal humans more rapidly exhaust carrying capacity—the maximum load an environment can sustain without undergoing degradation. Load has two dimensions (population, and per capita impacts). Until the industrial revolution reversed the effect, technology enlarged carrying capacity. Now technology enlarges per capita impacts and resource appetites. Homo colossus—man equipped with voracious technology—has reverted to hunting and gathering ("exploration and development") and his machines have become his ecological competitors. The number of people a finite world can support indefinitely is thus decreasing instead of increasing.
