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, 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.

The film was released to mainly positive reviews, and was generally considered a moderate financial success at both the box office and in home video sales. In 1998, it was followed by a direct-to-video sequel, FernGully 2: The Magical Rescue, although none of the original voice cast reprised their roles. (Full article...)
Robert Marshall (January 2, 1901 – November 11, 1939) was an American forester, writer and wilderness activist who is best remembered as the person who spearheaded the 1935 founding of the Wilderness Society in the United States. Marshall developed a love for the outdoors as a young child. He was an avid hiker and climber who visited the Adirondack Mountains frequently during his youth, ultimately becoming one of the first Adirondack Forty-Sixers. He also traveled to the Brooks Range of the far northern Alaskan wilderness. He wrote numerous articles and books about his travels, including the bestselling 1933 book Arctic Village.
A scientist with a PhD in plant physiology, Marshall became independently wealthy after the death of his father in 1929. He had started his outdoor career in 1925 as forester with the U.S. Forest Service. He used his financial independence for expeditions to Alaska and other wilderness areas. Later he held two significant public appointed posts: chief of forestry in the Bureau of Indian Affairs, from 1933 to 1937, and head of recreation management in the Forest Service, from 1937 to 1939, both during the administration of President Franklin D. Roosevelt. During this period, he directed the promulgation of regulations to preserve large areas of roadless land that were under federal management. Many years after his death, some of those areas were permanently protected from development, exploitation, and mechanization with the passage of the Wilderness Act of 1964. (Full article...)
The Brundtland Commission officially dissolved in 1987 after releasing Our Common Future, also known as the Brundtland Report. The document popularized the term "sustainable development" and won the Grawemeyer Award in 1991. In 1988, the Center for Our Common Future replaced the commission. (Full article...)

To waste, to destroy our natural resources, to skin and exhaust the land instead of using it so as to increase its usefulness, will result in undermining in the days of our children the very prosperity which we thought by right to hand down to them amplified and developed.
