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,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: 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.

Several groups specifically concerned with nuclear issues were established in the mid-1970s, including the Movement Against Uranium Mining and Campaign Against Nuclear Energy (CANE), cooperating with other environmental groups such as Friends of the Earth and the Australian Conservation Foundation. The movement suffered a setback in 1983 when the newly elected Labor Government failed to implement its stated policy of stopping uranium mining. But by the late 1980s, the price of uranium had fallen, the costs of nuclear power had risen, and the anti-nuclear movement seemed to have won its case; CANE was disbanded in 1988. (Full article...)

Deforestation is the conversion of forested areas to non-forest land use such as arable land, pasture, urban use, logged area, or wasteland. Generally, the removal or destruction of significant areas of forest cover has resulted in a degraded environment with reduced biodiversity.
National ecological surplus or deficit, measured as a country's biocapacity per person (in global hectares) minus its ecological footprint per person (also in global hectares). Data from 2013.

Image 12Cattails indicate the presence of phosphorus in the water. Cattails are an invasive species; they crowd out sawgrass and grow too thick to allow nesting for birds and alligators. (from Restoration of the Everglades)
Image 16An Antarctic rock split apart to show endolithic lifeforms showing as a green layer a few millimeters thick (from Habitat)
Image 17A false color composite of the greater Boston area, created using remote sensing technology, reveals otherwise not visible characteristics about the land cover and the health of the surrounding ecosystems. (from Environmental science)
Image 18Loch Lomond in Scotland forms a relatively isolated ecosystem. The fish community of this lake has remained stable over a long period until a number of introductions in the 1970s restructured its food web. (from Ecosystem)
Image 21Climbing ferns overtake cypress trees in the Everglades. The ferns act as "fire ladders" that can destroy trees that would otherwise survive fires. (from Restoration of the Everglades)
Image 22Few creatures make the ice shelves of Antarctica their habitat, but water beneath the ice can provide habitat for multiple species. Animals such as penguins have adapted to live in very cold conditions. (from Habitat)

Image 39Global oceanic and terrestrial phototroph abundance, from September 1997 to August 2000. As an estimate of autotroph biomass, it is only a rough indicator of primary production potential and not an actual estimate of it. (from Ecosystem)

Image 47Biodiversity of a coral reef. Corals adapt and modify their environment by forming calcium carbonate skeletons. This provides growing conditions for future generations and forms a habitat for many other species. (from Environmental science)
