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.

School Strike for Climate (Swedish: Skolstrejk för klimatet), also known variously as Fridays for Future (FFF), Youth for Climate, Climate Strike or Youth Strike for Climate, is an international movement of school students who skip Friday classes to participate in demonstrations to demand action from political leaders to prevent climate change and for the fossil fuel industry to transition to renewable energy.
Publicity and widespread organising began after Swedish pupil Greta Thunberg staged a protest in August 2018 outside of the Swedish Riksdag (parliament), holding a sign that read "Skolstrejk för klimatet" ("School strike for climate"). (Full article...)
Deforestation is the conversion of forested areas to non-forest land use such as arable land, pasture, urban use, logged area, or wasteland. Generally, the removal or destruction of significant areas of forest cover has resulted in a degraded environment with reduced biodiversity.
Ehrlich became well known for the controversial 1968 book The Population Bomb, which he co-authored with his wife Anne H. Ehrlich, in which they famously stated that "[i]n the 1970s hundreds of millions of people will starve to death in spite of any crash programs embarked upon now." Among the solutions suggested in that book was population control, including "various forms of coercion" such as eliminating "tax benefits for having additional children," to be used if voluntary methods were to fail, as well as letting "hopeless" countries like India starve to death.[need quotation to verify] (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...)

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.
... 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 each year in 22,500 cemeteries across the United States approximately 30 million board feet (70,000 m³) of hardwoods are buried as caskets?
... 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?
