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.

Marine conservation, also known as ocean conservation, is the protection and preservation of ecosystems in oceans and seas through planned management in order to prevent the over-exploitation of these marine resources. Marine conservation is informed by the study of marine plants and animal resources and ecosystem functions and is driven by response to the manifested negative effects seen in the environment such as species loss, habitat degradation and changes in ecosystem functions and focuses on limiting human-caused damage to marine ecosystems, restoring damaged marine ecosystems, and preserving vulnerable species and ecosystems of the marine life. Marine conservation is a relatively new discipline which has developed as a response to biological issues such as extinction and marine habitats change.
Marine conservationists rely on a combination of scientific principles derived from marine biology, Ecology, oceanography, and fisheries science, as well as on human factors, such as demand for marine resources, maritime law, economics, and policy, in order to determine how to best protect and conserve marine species and ecosystems. Marine conservation may be described as a sub-discipline of conservation biology. (Full article...)
... that Carol Van Strum, an environmental activist who wrote the book A Bitter Fog, accumulated 20,000 documents across 40 years that revealed corporate and government cover-ups?
... that American environmentalist Rosalie Edge was called "the only honest, unselfish, indomitable hellcat in the history of conservation"?
Irrigation is the artificial application of water to the soil usually for assisting in growing crops. In crop production it is mainly used to replace missing rainfall in periods of drought, but also to protect plants against frost. Additionally irrigation helps to suppress weed growing in rice fields. In contrast, agriculture that relies only on direct rainfall is sometimes referred to as dryland farming or as rain fed farming. Environmental problems such depletion of underground aquifers, ground subsidence, buildup of toxic salts on soil surface in areas of high evaporation, overirrigation and the possibility of water pollution.
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.

Rainforest Action Network (RAN) is an environmental organization based in San Francisco, California, United States. The organization was founded by Randy "Hurricane" Hayes and Mike Roselle in 1985, and first gained national prominence with a grassroots organizing campaign that in 1987 succeeded in convincing Burger King to cancel $31 million worth of destructive Central American rainforest beef contracts. Protecting forests and challenging corporate power has remained a key focus of RAN’s campaigns since, and has led RAN into campaigns that have led to transformative policy changes across home building, wood purchasing and supplying, automobile, fashion, paper and banking industries.

Many scientists are now warning that we are moving closer to several "tipping points" that could — within as little as 10 years — make it impossible for us to avoid irretrievable damage to the planet's habitability for human civilization.

...that chlorofluorocarbons (CFCs) can cause ozone depletion, and the ozone hole needs to take more than a decade to recover?
... that the idea of atmospheric gases trapping the Suns heat to produce the greenhouse effect was put forward by Joseph Fourier in the 1820’s?
... 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 rivers have been classified by many criteria, including their topography, their biotic status and their relevance to white water rafting and canoeing activities?
... that Summer Rayne Oakes has been called "the world's first eco-model" because she only models clothes made from organic or recycled materials?
