The natural environment, commonly known simply as the environment, are all living and non-living things that occur naturally on Earth or in some part of it (for example, the natural environment of a country). This includes complete ecological units that function as natural systems without massive human intervention, including all the vegetation, animals, microorganisms, rocks, atmosphere and natural phenomena that occur within their limits. And it includes universal natural resources and physical phenomena that lack precise limits, such as air, water and climate, as well as energy, radiation, electrical charge and magnetism, which do not originate in human activity.
