Nature (also called the material world, the material universe, the natural world, and the natural universe) is all matter and energy, especially in its essential form, untainted by human influence. Nature is the subject of scientific study.
In scale, 'nature' includes everything from the universal to the subatomic. This includes all things animal, plant, and mineral; all natural resources and events (hurricanes, tornadoes, earthquakes). It also includes the behaviour of living animals, and the processes associated with inanimate objects.
A fundamental difference of view exists between those who include humans (both their consciousness and their activities) within nature, and those who do not.
Life, the characteristics and behaviors of organisms, how species and individuals come into existence, and the interactions they have with each other and with their environment are all in the natural science of biology.
In philosophy, the view that the material world of atoms, animals, gravity, stars, wind, microbes, etc., actually exist independently of our observations of them is termed realism; the opposing view is called idealism.
