Conservation Biology
the scientific study of how
humans impact organisms
and of the development of
ways to protect biological
diversity
Conservation Biologists
believe it is more effective
and, ultimately, more
economical to preserve …
intact ecosystems in which
many species live than to
work on preserving individual
species one at a time
