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.

In 2011, the International Energy Agency said that "the development of affordable, inexhaustible and clean solar energy technologies will have huge longer-term benefits. It will increase countries' energy security through reliance on an indigenous, inexhaustible, and mostly import-independent resource, enhance sustainability, reduce pollution, lower the costs of mitigating global warming .... these advantages are global".

The passenger pigeon was a species of pigeon that was once the most common bird in North America. It is estimated that there were as many as five billion passenger pigeons in the United States at the time Europeans colonized North America. They lived in enormous flocks, and during migration, one could see flocks of them a mile (1.6 km) wide and 300 miles (500 km) long, taking several days to pass and probably containing two billion birds. The species had not been common in the Pre-Columbian period, until the devastation of the American Indian population by European diseases.
Over the 19th century, the species went from being one of the most abundant birds in the world to extinction. At the time, passenger pigeons had one of the largest groups or flocks of any animal, second to only the desert locust.
Some decimation in numbers occurred as a result of loss of habitat, when the Europeans started settling further inland. However, the primary factor emerged when pigeon meat was commercialized as a cheap food for slaves and the poor in the 19th century, resulting in hunting on a massive scale. There was a slow decline in their numbers between about 1800 and 1870, followed by a catastrophic decline between 1870 and 1890, at the end of which they were rare and beyond the point of recovery. 'Martha', thought to be the world's last passenger pigeon, died on September 1, 1914 in Cincinnati.
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.

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.
