Inexhaustible natural resources – resources, the amount of which is not limited, but not absolutely, but relative to our needs and terms of existence. Inexhaustible natural resources include water resources (waters of the World Ocean), climatic (atmospheric air, wind energy) and space (solar radiation, tidal energy). However, if the amount of inexhaustible natural resources is relatively unlimited, then their quality may limit the possibility of their use by humans (for example, the amount of water is not limited, but the amount of drinking water is limited).
