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.

The Northwest Exelon Pavilion is the Millennium Park Welcome Center and houses the park's office.
The Exelon Pavilions are four buildings that generate electricity from solar energy and provide access to underground parking in Millennium Park in the Loopcommunity area of Chicago in Cook County, Illinois, United States. The Northeast Exelon Pavilion and Northwest Exelon Pavilion (jointly the North Exelon Pavilions) are located on the northern edge of the park along Randolph Street, and flank the Harris Theater. The Southeast Exelon Pavilion and Southwest Exelon Pavilion (jointly the South Exelon Pavilions) are located on the southern edge of the park along Monroe Street, and flank the Lurie Garden. Together the pavilions generate 19,840 kilowatt-hours (71,400 MJ) of electricity annually, worth about $2,350 per year.
The four pavilions, which cost $7 million, were designed in January 2001; construction began in January 2004. The South Pavilions were completed and opened in July 2004, while the North Pavilions were completed in November 2004, with a grand opening on April 30, 2005. In addition to producing energy, three of the four pavilions provide access to the parking garages below the park, while the fourth serves as the park's welcome center and office. Exelon, a company that generates the electricity transmitted by its subsidiary Commonwealth Edison, donated $5.5 million for the pavilions. Chicago Tribune architecture critic Blair Kamin praised the South Pavilions as "minor modernist jewels", but criticized the North Pavilions as "nearly all black and impenetrable". The North Pavilions have received the Leadership in Energy and Environmental Design (LEED) silver rating from the United States Green Building Council, as well as an award from the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE).

On a fundamental level, Harkin's philosophy had two dominant components: the economic, which saw park lands in commercial terms, and the humanitarian which saw parks as being integral to the well-being of the human spirit on a physical, mental and moral level. In successfully bringing these two principles together in a symbiotic way, Harkin was able to facilitate the incredible growth of Canadian tourism and, at the same time, justify his conservationist goals.

GCP's Global Carbon Budget 2021 presented research (Friedlingstein et al. 2021) showing cumulative contributions to the global carbon budget since 1850 to illustrate how carbon source and sink components have been out of balance, causing an approximately 50% rise in atmospheric carbon dioxide concentration
The main object of the group has been to fully understand the carbon cycle. The project has brought together emissions experts, earth scientists, and economists to tackle the problem of rising concentrations of greenhouse gases. In 2020, the project released its newest Global Methane Budget and first Global Nitrous Oxide Budget, the two anthropogenic trace gases most dominant for warming after carbon dioxide.

... that the concept of reduce, re-use, and recycle as three equal options, but they are instead meant to be a hierarchy, in order of importance?
... that each year in 22,500 cemeteries across the United States approximately 30 million board feet (70,000 m³) of hardwoods are buried as caskets?
... 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?
