Bioregionalism is a contemporary environmental movement containing det
erministic ideas similar to those of geography's environmental determi
nism. This paper examines the theoretical and practical implications f
or bioregionalism based upon the experience of geography by identifyin
g parallels between bioregionalism and environmental determinism in te
rms of both culture and politics. While not a latter day form of envir
onmental determinism, bioregionalism deterministically links political
culture and the environment. By comparing and contrasting environment
al determinism with bioregionalism's deterministic tendencies, I ident
ify certain contradictory ideas within bioregionalism. Among the most
important contradictions occur when bioregionalists base moral judgeme
nts on a form of environmentalism, and when they advocate self determi
nation while promoting environmentally determined lifeways. These idea
s lie at the intersection of bioregionalism's social and ecological ob
jectives-where the deterministic nature of bioregionalism is at odds w
ith bioregionalism's decentralized, egalitarian philosophy.
