The natural environment encompasses all living and non-living things that occur naturally, which means that in this case it is not artificial. The term is most commonly applied to Earth or parts of the Earth. This environment encompasses the interaction of all living species, climate, climate and natural resources that affect human survival and economic activity. The concept of 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, atmosphere, and natural phenomena occurring within its boundaries and nature
• Universal natural resources and physical phenomena that lack clear boundaries, such as air, water and climate, as well as energy, radiation, electric charge and magnetism, which do not come from civilized human activity.
In contrast to the natural environment is the built environment. In those areas where man has fundamentally transformed landscapes such as urban architecture and the conversion of agricultural land, the natural environment is greatly modified in a simplified human environment. Even acts that seem less extreme, such as building a mud hut or a photovoltaic system in the desert, modify the natural environment into an artificial one. Although many animals build things to provide a better environment for themselves, they are not human, therefore beaver prey and mound building termites are considered natural.
People rarely find absolutely natural environments on Earth, and naturalness generally varies in a continuum, from 100% natural at one end to 0% natural at 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 example, in an agricultural field, the mineralogical composition and the structure of its soil are similar to those of an undisturbed forest soil, but the structure is quite different. The natural environment is often used as a synonym for habitat. For example, when we say that the natural environment of the giraffes is the savannah.
