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 dam's body was completed in 2006; the power plant became fully operational in 2012, when the last of the main water turbines in the underground plant began production. The last major component of the project, the ship lift, was completed in 2015. The dam, measuring 185 meters in height and 2,309 meters in width, significantly surpasses Brazil’s 12,600 MW Itaipu facility and is one of the world's largest hydroelectric plants. (Full article...)

ZENN (Zero Emission, No Noise) is a 2-seated car that runs solely on battery. It has a range of up to 60 km and does not exceed 40 km/h. The fuel economy is few cents per kilometer and the MSRP is $12,000.
Although the company is headquartered in Canada and the car manufactured in Canada, the vehicle was first introduced in United States because at the time of vehicle's design phrase, Canadian laws prevents this car to be driven on the roads. Since 2000, British Columbia has allowed ZENN cars on its roads.
David Takayoshi SuzukiCCOBCFRSC (born March 24, 1936) is a Canadian academic, science broadcaster, and environmental activist. Suzuki earned a PhD in zoology from the University of Chicago in 1961, and was a professor in the genetics department at the University of British Columbia from 1963 until his retirement in 2001. Since the mid-1970s, Suzuki has been known for his television and radio series, documentaries and books about nature and the environment. He is best known as host and narrator of the popular and long-running CBC Television science program The Nature of Things, seen in over 40 countries. He is also well known for criticizing governments for their lack of action to protect the environment.
