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.

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".

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.
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...)
BirdLife International is a global partnership of non-governmental organizations that strives to conserve birds and their habitats. BirdLife International's priorities include preventing extinction of bird species, identifying and safeguarding important sites for birds, maintaining and restoring key bird habitats, and empowering conservationists worldwide.

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 chlorofluorocarbons (CFCs) can cause ozone depletion, and the ozone hole needs to take more than a decade to recover?
... that the idea of atmospheric gases trapping the Suns heat to produce the greenhouse effect was put forward by Joseph Fourier in the 1820’s?
... that the concept of reduce, re-use, and recycle as three equal options, but they are instead meant to be a hierarchy, in order of importance?
... that rivers have been classified by many criteria, including their topography, their biotic status and their relevance to white water rafting and canoeing activities?
... that Liberian lawyer Alfred Brownell won the "Green Nobel" prize for his efforts to protect more than 500,000 acres (2,000 km2) of tropical forest land?
