The terms nature and natural each have several different meanings which can
lead to confusion in communications about environmental issues. One approa
ch to clarifying discussion, frequently used in the sciences, is to develop
precise, operational definitions of terminology. We argue that this approa
ch can be ineffective when applied to multifaceted conceptual terms such as
nature, natural, and culture. We think the range of legitimate meanings fo
r these terms may be better communicated by historical accounts of use that
describe the assumptions, contexts, and worldviews associated with differe
nt interpretations. These accounts do not resolve disagreement but can help
clarify the basis for it, and open up new avenues of inquiry. In this pape
r, we examine the terms nature, natural environment, environmental change,
and environmental degradation. A recent article in this journal offered pre
cise definitions of the last three of these terms that were based on the id
ea that natural is that which is relatively uninfluenced by human culture.
Although this is a commonly accepted meaning of natural, we contend that th
is meaning needs to be carefully scrutinized. We identify specific problems
with this usage and offer an account of use of the term nature, which we t
hink provides a more thorough understanding of how nature and natural have
been used and understood in different contexts. Since the term natural can
be understood several different ways, communication of any particular meani
ng requires careful articulation of the intended meaning in light of severa
l alternative interpretations.
