The natural environment, commonly referred to simply as the environment, is all living things and non-living things that occur naturally on the earth or some part of it (eg, the natural environment in a country). This includes 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. E includes 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 human activity.
