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.

Some of the book's subjects have been critical of the book, but most reviewers received it favorably. It was made into a film, Merchants of Doubt, directed by Robert Kenner, released in 2014. (Full article...)
... that the volcano Carachipampa is surrounded by a lake and a salt flat, and has a Mars-like environment?
... that "Look at the world" is a 1996 choral harvest anthem with text and music by John Rutter, written for CPRE "on the theme of the environment and our responsibility towards it"?
Through legal interventions, advocacy and public campaigns, contribution to documentary films, television debates and press articles she has successfully mainstreamed and built consciousness about previously unknown environmental hazards, notably noise pollution and sand mining, and has won national and International awards for her work. She also set up the first network for protection of activists in India after an attack on her by the sand mafia is 2004. (Full article...)
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 4Few 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 12Loch 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 15Compartments established by C&SF projects that separated the historic Everglades into Water Conservation Areas and the Everglades Agricultural Area. One-fourth of the original Everglades is preserved in Everglades National Park. (from Restoration of the Everglades)

Image 19The Paris Agreement (formerly the Kyoto Protocol) is adopted in 2016. Nearly every country in the United Nations has signed the treaty, which aims to reduce greenhouse gas emissions. (from Environmental science)

Image 32A team of British researchers found a hole in the ozone layer forming over Antarctica, the discovery of which would later influence the Montreal Protocol in 1987. (from Environmental science)
Image 37Biodiversity 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)
Image 38Global 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 50Cattails 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 55Climbing 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)
... that Liberian lawyer Alfred Brownell won the "Green Nobel" prize for his efforts to protect more than 500,000 acres (2,000 km2) of tropical forest land?
