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. (Full article...)

Brown is the author or co-author of over 50 books on global environmental issues and his works have been translated into more than forty languages. His most recent book is The Great Transition: Shifting from Fossil Fuels to Solar and Wind Energy (2015), in which he explains that the global economy is now undergoing a transition from fossil and nuclear energy to clean power from solar, wind, and other renewable sources. His previous book was Full Planet, Empty Plates: The New Geopolitics of Food Scarcity (2012). (Full article...)
The International Geosphere-Biosphere Programme (IGBP) was a research programme that ran from 1987 to 2015 dedicated to studying the phenomenon of global change. Its primary focus was coordinating "international research on global-scale and regional-scale interactions between Earth's biological, chemical and physical processes and their interactions with human systems."
The International Council of Scientific Unions, a coordinating body of national science organizations, launched IGBP. It looked at the total Earth system, the changes that are occurring, and the manner in which changes are influenced by human actions. (Full article...)

You don’t listen to the science because you are only interested in solutions that will enable you to carry on like before. Like now. And those answers don’t exist any more. Because you did not act in time.
... that rivers have been classified by many criteria, including their topography, their biotic status and their relevance to white water rafting and canoeing activities?
