The natural environment encompasses all living and non-living things occurring naturally on Earth or some region thereof. It is an environment that encompasses the interaction of all living species. The concept of the natural environment can be distinguished by components:
Complete ecological units that function as natural systems without massive human intervention, including all vegetation, microorganisms, soil, rocks, atmosphere, and natural phenomena that occur within their boundaries.
Universal natural resources and physical phenomena 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.
The natural environment is contrasted with the built environment, which comprises the areas and components that are strongly influenced by humans. A geographical area is regarded as a natural environment.
It is difficult to find absolutely natural environments, and it is common that the naturalness varies in a continuum, from ideally 100% natural in one extreme to 0% natural in the other. 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, we take an agricultural field, and consider the mineralogic composition and the structure of its soil, we will find that whereas the first is quite similar to that of an undisturbed forest soil, the structure is quite different.
Natural environment is often used as a synonym for habitat. For instance, when we say that the natural environment of giraffes is the savanna.

The surrounding in which we live makes up our environment.The environment of living things provides conditions for development and growth.Organisms change in response to conditions in their environment and surroundings.Environment is of two types natural environment and artificial or man-made environment.The natural environment comprises of natural things present near us like sun,plants etc.Whereas,artificial environment is made by artificial things present near us like dams,buildings etc.These environmental components are considered as the resources and are mostly exploited and utilized by the men to fulfill their basic physical needs they can be considered as the fellow members of the global eco-system with which men establish emotional, intellectual, or physical relationships and these provide the basis for a sense of purpose of life to them.Thus, man is firmly placed as an important part of the global ecosystem, which depends on him much as he depends on it. Hence, there is a close relationship between man and environment.
