Introduction
The natural environment or natural world encompasses all living and non-living 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:
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.

Earth's climate system is a complex system with five interacting components: the atmosphere (air), the hydrosphere (water), the cryosphere (ice and permafrost), the lithosphere (earth's upper rocky layer) and the biosphere (living things). Climate is the statistical characterization of the climate system. It represents the average weather, typically over a period of 30 years, and is determined by a combination of processes, such as ocean currents and wind patterns. Circulation in the atmosphere and oceans transports heat from the tropical regions to regions that receive less energy from the Sun. Solar radiation is the main driving force for this circulation. The water cycle also moves energy throughout the climate system. In addition, certain chemical elements are constantly moving between the components of the climate system. Two examples for these biochemical cycles are the carbon and nitrogen cycles.
... that clothing physiology is the study of how clothing interacts with the human body and the environment?
... that Mycobacterium bacterial species constantly remodel their cell wall layers to survive in stressful environments and avoid their host's immune defenses?
... that environmental defenders on the front of the global environmental justice movement are being killed at a rate of about three per week?
... that critics objected to Dangers of the Mail in the 1930s for government support of lewdness and in the 2000s for creating a hostile work environment?
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.
Næss averred that while western environmental groups of the early post–World War II period had raised public awareness of the environmental issues of the time, they had largely failed to have insight into and address what he argued were the underlying cultural and philosophical background to these problems. Næss believed that the environmental crisis of the twentieth century had arisen due to certain unspoken philosophical presuppositions and attitudes within modern western developed societies which remained unacknowledged.

ClimateWorks Foundation is a San Francisco-based nonprofit organization founded in 2008. ClimateWorks Foundation's mission is to slow global warming by funding other organizations internationally to help find best practice solutions to cut down on carbon dioxide (CO2) emissions .
In 2016 the nonprofit was listed as one of the Top 100 Largest U.S. Charities by Forbes Magazine. The ClimateWorks Foundation is part of the Partner Circle of the Foundations Platform F20, an international network of foundations and philanthropic organizations. (Full article...)

Image 4Global 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 5Few 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 7The 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)
