The natural environment or natural world encompasses all biotic and abiotic things occurring naturally, meaning in this case not artificial. The term is most often applied to Earth or some parts of Earth. This environment encompasses the interaction of all living species, climate, weather and natural resources that affect human survival and economic activity.
The concept of the natural environment can be distinguished as components:
Complete ecological units that function as natural systems without massive civilized human intervention, including all vegetation, microorganisms, soil, rocks, plateaus, mountains, the atmosphere and natural phenomena that occur within their boundaries and their nature.
In contrast to the natural environment is the built environment. Built environments are where humans have fundamentally transformed landscapes such as urban settings and agricultural land conversion, the natural environment is greatly changed into a simplified human environment. Even acts which seem less extreme, such as building a mud hut or a photovoltaic system in the desert, the modified environment becomes an artificial one. Though many animals build things to provide a better environment for themselves, they are not human, hence beaver dams and the works of mound-building termites are thought of as natural.

People cannot find absolutely natural environments on Earth, naturalness usually varies in a continuum, from 100% natural in one extreme to 0% natural in the other. The massive environmental changes of humanity in the Anthropocene have fundamentally effected all natural environments including: climate change, biodiversity loss and pollution from plastic and other chemicals in the air and water. More precisely, we can consider the different aspects or components of an environment, and see that their degree of naturalness is not uniform. If, for instance, in an agricultural field, the mineralogic composition and the structure of its soil are similar to those of an undisturbed forest soil, but the structure is quite different.

Environmental psychology is a branch of psychology that explores the relationship between humans and the external world. It examines the way in which the natural environment and our built environments shape us as individuals. Environmental psychology investigates how humans change the environment and how the environment influences humans' experiences and behaviors. The field defines the term environment broadly, encompassing natural environments, social settings, built environments, learning environments, and informational environments. According to an article on APA Psychnet, environmental psychology is when a person thinks to a plan, travels to a certain place, and follows through with the plan throughout their behavior.
Environmental psychology was not fully recognized as its own field until the late 1960s when scientists began to question the tie between human behavior and our natural and built environments. Since its conception, the field has been committed to the development of a discipline that is both value oriented and problem oriented, prioritizing research aimed at solving complex environmental problems in the pursuit of individual well-being within a larger society.

In addition to political advocacy, the Sierra Club organizes outdoor recreation activities, and has historically been a notable organization for mountaineering and rock climbing in the United States. Members of the Sierra Club pioneered the Yosemite Decimal System of climbing, and were responsible for a substantial amount of the early development of climbing. Much of this activity occurred in the group's namesake, the Sierra Nevada. The Sierra Club operates only in the United States and holds the legal status of 501(c)(4)nonprofit social welfare organization. Sierra Club Canada is a separate entity. (Full article...)
