Au sens commun la Nature regroupe :
- des paysages et milieux naturels (terrestres) ; préservés (à forte naturalité) et dégradés ; 
- les « forces » et principes physiques, géologiques, tectonique, météorologique, biologique, l'évolution qui constituent l'univers et animent les écosystèmes et la biosphère sur la planète Terre; 
- les milieux (eau, air, sol air, mers, monde minéral ; 
- les espèces et le monde végétal (forêts...), animal (dont l'espèce humaine), fongique, bactérien et plus généralement microbien

- certains phénomènes épisodiques de la nature (crises, cycles glaciations/réchauffement climatique, Cycles géologiques, Cycle sylvigénétique, incendies d'origine non-humaine, etc.). 

Face au constat des répercussions négatives sur l'environnement des activités humaines et la perte accéléré de naturalité et de biodiversité au cours des dernières décennies, la protection de la nature et des milieux naturels, la sauvegarde des habitats et des espèces, la mise en place d'un développement durable et raisonnable et l'éducation à l'environnement sont devenues des demandes pour une grande partie des citoyens de la plupart des pays industrialisés. Elles fondent les principes de l'éthique environnementale et de nouvelles lois et chartes de protection de l'environnement.

Nature, in the broadest sense, is equivalent to the natural world, physical universe, material world or material universe. "Nature" refers to the phenomena of the physical world, and also to life in general. The term generally does not include manufactured objects and human interaction unless qualified in ways such as, e.g., "human nature" or "the whole of nature". Nature is also generally distinguished from the supernatural. It ranges in scale from the subatomic to the galactic.

Within the various uses of the word today, "nature" may refer to the general realm of various types of living plants and animals, and in some cases to the processes associated with inanimate objects – the way that particular types of things exist and change of their own accord, such as the weather and geology of the Earth, and the matter and energy of which all these things are composed. It is often taken to mean the "natural environment" or wilderness – wild animals, rocks, forest, beaches, and in general those things that have not been substantially altered by human intervention, or which persist despite human intervention. This more traditional concept of natural things which can still be found today implies a distinction between the natural and the artificial, with the latter being understood as that which has been brought into being by a human or human-like consciousness or mind.

The development of technology by the human race has allowed the greater exploitation of natural resources and has helped to alleviate some of the risk from natural hazards. In spite of this progress, however, the fate of human civilization remains closely linked to changes in the environment. There exists a highly complex feedback-loop between the use of advanced technology and changes to the environment that are only slowly becoming understood. Manmade threats to the Earth's natural environment include pollution, deforestation, and disasters such as oil spills. Humans have contributed to the extinction of many plants and animals.
