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...)
Nanotechnology refers broadly to a field of applied science and technology whose unifying theme is the control of matter on the molecular level in scales smaller than 1 micrometre, normally 1 to 100 nanometers, and the fabrication of devices within that size range. Nanopollution is the result of waste generated by nanotechnology and has implications on the wider environment.
As a beneficiary of the Kennedy Airlift, she studied in the United States, earning a bachelor's degree from Mount St. Scholastica and a master's degree from the University of Pittsburgh. She went on to become the first woman in East and Central Africa to become a Doctor of Philosophy, receiving her Ph.D. from the University of Nairobi in Kenya. In 1984, she got the Right Livelihood Award for "converting the Kenyan ecological debate into mass action for reforestation." Wangari Maathai was an elected member of the Parliament of Kenya and, between January 2003 and November 2005, served as Assistant Minister for Environment and Natural Resources in the government of President Mwai Kibaki. She was an Honorary Councillor of the World Future Council. As an academic and the author of several books, Maathai was not only an activist but also an intellectual who has made significant contributions to thinking about ecology, development, gender, and African cultures and religions.
