As global environmental problems intensify, ecology is increasingly drawn i
nto the social arena, and many ecologists feel caught between two competing
models of science: a science apart from society and a science directly eng
aged with society. Interdisciplinary research and integrative theories are
helping resolve this conflict by providing a common framework for both biop
hysical and social sciences. The incorporation of the human dimension into
ecology is reversing a century-old trend of separation and reintegrating sc
ience into the human experience.
