Anthropology Has Always Been Concerned with How Environmental Forces Influence

Anthropology has always been concerned with how environmental forces influence humans, and how human activities affect the biosphere and the earth itself. The 1950s through the 1970s witnessed the emergence of an area of study known as cultural ecology or ecological anthropology. This field

A) focused on how cultural beliefs and practices help human populations adapt to their environment.
B) studied etic perspectives on human-environment relationships.
C) is no longer relevant, because it dealt with research models that were either regional or local, but not global enough to account for the changes caused by climate change.
D) has limited present value, because it is not scientifically rigorous enough to address environmental problems.
E) studied human-environment relations as cultural constructions and analyzed them as "texts."
