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 those in which humans have fundamentally transformed landscapes such as in urban settings and agricultural land conversion. Even in acts that seem less extreme, such as building a mud hut or a photovoltaic system in the desert, the modified environment is considered artificial. 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 considered natural.
There are no 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 affected all natural environments including: climate change, biodiversity loss and pollution from plastic and other chemicals in the air and water. More precisely, considering the different aspects or components of an environment, it becomes apparent that their degree of naturalness is not uniform. For instance, in an agricultural field, the mineralogic composition is quite similar to that of undisturbed forest soil while the structure is quite different. (Full article...)
The Great Barrier Reef is the world's largest reef systems, stretching along the East coast of Australia from the northern tip down at Cape York to the town of Bundaberg, is composed of roughly 2,900 individual reefs and 940 islands and cays that stretch for 2,300 kilometres (1,616 mi) and cover an area of approximately 344,400 square kilometres (133,000 sq mi). The reef is located in the Coral Sea, off the coast of Queensland in northeast Australia. A large part of the reef is protected by the Great Barrier Reef Marine Park.
According to the 2014 report of the Australian Government'sGreat Barrier Reef Marine Park Authority (GBRMPA), says that climate change is the most significant environmental threat to the Great Barrier Reef, while the other major environmental pressures are listed as decreased water quality from land-based runoff, impacts from coastal development and some persistent impacts from fishing activities. The reef is also threatened by storms, coral bleaching and ocean acidification. The 2014 report also shows that, while numerous marine life species have recovered after previous declines, the strength of the dugong population is continuing to decline. Terry Hughes, Federation Fellow, ARC Centre of Excellence for Coral Reef Studies at James Cook University, wrote in a 14 August 2014 Conversation piece that harmful government policies and ongoing conflicts of interest over mining royalties are risks of an equivalent magnitude.

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.
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.

Originally part of the Department of the Environment (DOENI), the agency was called the Environment and Heritage Service (EHS) until 1 July 2008, and also had responsibility for the historic environment. On 16 May 2016 the DOENI was dissolved and NIEA became part of DAERA. At the same time, the historic environment functions of NIEA were transferred to the Department for Communities.

With the growing urgency of climate change, we cannot have it both ways. We cannot shout from the rooftops about the dangers of global warming and then turn around and shout even louder about the "dangers" of windmills.
... 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?
