The natural environment or natural world encompasses all living and non-living 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:
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.

Renewable energy systems are rapidly becoming more efficient and cheaper. As a result, their share of global energy consumption is increasing. A large majority of worldwide newly installed electricity capacity is now renewable. In most countries, photovoltaic solar or onshore wind are the cheapest new-build electricity. Renewable energy can help reduce energy poverty in rural and remote areas of developing countries, where lack of energy access is often hindering economic development. Renewable energy resources exist all over the world. This is in contrast to fossil fuels resources which are concentrated in a limited number of countries. (Full article...)

Educated as a physician, Brundtland joined the Labour Party and entered the government in 1974 as Minister of the Environment. She became the first female prime minister of Norway on 4 February 1981, but left office on 14 October 1981; she returned as prime minister on 9 May 1986 and served until 16 October 1989. She finally returned for her third term on 3 November 1990. After her surprise resignation as prime minister in 1996, she became an international leader in sustainable development and public health, and served as Director-General of the World Health Organization and as UN Special Envoy on Climate Change from 2007 to 2010. She is also deputy chair of The Elders and a former vice-president of Socialist International. (Full article...)

Image 1Biodiversity of a coral reef. Corals adapt and modify their environment by forming calcium carbonate skeletons. This provides growing conditions for future generations and forms a habitat for many other species. (from Environmental science)

There must be a reason why some people can afford to live well. They must have worked for it. I only feel angry when I see waste. When I see people throwing away things we could use.
... 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 the average United States citizen consumes 119pg (10−12 g) of dioxin per day?
... 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?
