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.
