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.

An invasive species is an introduced species to an environment that becomes overpopulated and harms its new environment. Invasive species adversely affect habitats and bioregions, causing ecological, environmental, and/or economic damage. The term can also be used for native species that become harmful to their native environment after human alterations to its food web. Since the 20th century, invasive species have become a serious economic, social, and environmental threat worldwide.

Thunberg's climate activism began when she persuaded her parents to adopt lifestyle choices that reduced her family's carbon footprint. On 20 August 2018, at age 15, Thunberg began skipping school, vowing to remain out of school until after the national Swedish election in an attempt to influence the outcome. She protested outside the Swedish parliament where she called for stronger action on climate change by holding up a Skolstrejk för klimatet (School Strike for Climate) sign and handing out informational flyers. After the election, Thunberg spoke in front of her supporters, telling them to use their phones to film her. She then said that she would be continuing school striking for the climate every Friday until Sweden was in compliance with the 2015 Paris climate agreement. Thunberg's youth and blunt speaking manner fueled her rise to the status of a global icon. (Full article...)
NASA Earth Observatory, 2009. Deforestation in Malaysian Borneo.REDD+ (or REDD-plus) is a framework to encourage developing countries to reduce emissions and enhance removals of greenhouse gases through a variety of forest management options, and to provide technical and financial support for these efforts. The acronym refers to "reducing emissions from deforestation and forest degradation in developing countries, and the role of conservation, sustainable management of forests, and enhancement of forest carbon stocks in developing countries". REDD+ is a voluntary climate change mitigation framework developed by the United Nations Framework Convention on Climate Change (UNFCCC). REDD originally referred to "reducing emissions from deforestation in developing countries", which was the title of the original document on REDD. It was superseded by REDD+ in the Warsaw Framework on REDD-plus negotiations.Since 2000, various studies estimate that land use change, including deforestation and forest degradation, accounts for 12-29% of global greenhouse gas emissions. For this reason the inclusion of reducing emissions from land use change is considered essential to achieve the objectives of the UNFCCC. (Full article...)
