However, over the years, particularly since the
advent of the industrial revolution and the capitalistic
mode of production, one can discern similar trends
in western environmental values. Development of
new conservation concepts in one region usually
spread and had an influence on conservation movements
in other regions. Researchers of the history of
western conservation movements acertained that, as
pristine nature areas in the western world dwindled,
the value of the urge to conserve the few remaining
wilderness areas increased proportionately.
