The natural environment, commonly referred to simply as the environment, is a terminology that comprises all living and non-living things that occur on Earth or some region thereof.
This term includes a few key components, such as: complete ecological units that function as natural systems without massive human intervention, including all vegetation, animals, microorganisms, rocks, atmosphere and natural phenomena that occur within their boundaries.
Universal natural resources and physical phenomena are those that lack clear-cut boundaries, such as air, water, and climate, as well as energy, radiation, electric charge, and magnetism, not originating from human activity. dfg
The natural environment is contrasted with the built environment, which comprises the areas and components that are strongly influenced by man.
A geographical area is regarded as a natural environment, if the human impact on it is kept under a certain limited level. This level depends on the specific context, and changes in different areas and contexts. ffgfg
