The natural environment or natural world encompasses all biotic and abiotic things occurring naturally, meaning in this case not artificial. The term is most often applied to Earth or some parts of Earth. This environment encompasses the interaction of all living species, climate, weather and natural resources that affect human survival and economic activity.
The concept of the natural environment can be distinguished as components:
Complete ecological units that function as natural systems without massive civilized human intervention, including all vegetation, microorganisms, soil, rocks,plateaus, mountains, the atmosphere, and natural phenomena that occur within their boundaries and their nature.
In contrast to the natural environment is the built environment. Built environments are where humans have fundamentally transformed landscapes such as urban settings and agricultural land conversion, the natural environment is greatly changed into a simplified human environment. Even acts which seem less extreme, such as building a mud hut or a photovoltaic system in the desert, the modified environment becomes an artificial one. Though many animals build things to provide a better environment for themselves, they are not human, hence beaver dams, and the works of mound-building termites, are thought of as natural.

People cannot find absolutely natural environments on Earth, and naturalness usually varies in a continuum, from 100% natural in one extreme to 0% natural in the other. The massive environmental changes of humanity in the Anthropocene have fundamentally effected all natural environments: including from climate change, biodiversity loss and pollution from plastic and other chemicals in the air and water. More precisely, we can consider the different aspects or components of an environment, and see that their degree of naturalness is not uniform. If, for instance, in an agricultural field, the mineralogic composition and the structure of its soil are similar to those of an undisturbed forest soil, but the structure is quite different.

The film was released to mainly positive reviews, and was generally considered a moderate financial success at both the box office and in home video sales. In 1998, it was followed by a direct-to-video sequel, FernGully 2: The Magical Rescue, although none of the original voice cast reprised their roles. (Full article...)

... that Mycobacterium bacterial species constantly remodel their cell wall layers to survive in stressful environments and avoid their host's immune defenses?
... that the algal species Trachelomonas cervicula has been observed in environments highly polluted with cadmium, lead, and zinc?
... that Enriqueta Medellín, a Mexican surgeon, has an ecological center and environmental prize named after her in the state of Aguascalientes?
Wind Power is the conversion of wind energy into more useful forms, usually electricity, using wind turbines. The energy is generated in the form of electricity by converting the rotation of turbine blades into electrical current by means of an electrical generator. Wind power is used in large scale wind farms for national electrical grids as well as in small individual turbines for providing electricity to rural residences or grid-isolated locations.
The agency is led by its administrator, who is appointed by the president and approved by the Senate. The current administrator is Michael S. Regan. The EPA is not a Cabinet department, but the administrator is normally given cabinet rank. The EPA has its headquarters in Washington, D.C.. There are regional offices for each of the agency's ten regions, as well as 27 laboratories around the country. (Full article...)

The use of sea and air is common to all; neither can a title to the ocean belong to any people or private persons, forasmuch as neither nature nor public use and custom permit any possession therof.
...that many countries that signed the Kyoto Protocol actually increased the greenhouse gasemissions, contrary to the treaty? And for that, the 15 January 2011, a representative of the country had to stick their head in a hole of sand in Cancun, Mexico?
