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.

Food waste in the United Kingdom is a subject of environmental, and socioeconomic concern that has received widespread media coverage and been met with varying responses from government. Since 1915, food waste has been identified as a considerable problem and has been the subject of ongoing media attention, intensifying with the launch of the "Love Food, Hate Waste" campaign in 2007. Food waste has been discussed in newspaper articles, news reports and television programmes, which have increased awareness of it as a public issue. To tackle waste issues, encompassing food waste, the government-funded "Waste & Resources Action Programme" (WRAP) was created in 2000.
A significant proportion of food waste is produced by the domestic household, which in 2007[needs update] created 6,700,000 tonnes of food waste. Potatoes, bread slices and apples are the most wasted foods by quantity, while salads are thrown away in the greatest proportion. A majority of food waste food is avoidable,[d] with the rest being divided almost equally into foods which are unavoidable (e.g. tea bags) and those that are unavoidable due to preference (e.g. bread crusts) or cooking type (e.g. potato skins).

Irrigation is the artificial application of water to the soil usually for assisting in growing crops. In crop production it is mainly used to replace missing rainfall in periods of drought, but also to protect plants against frost. Additionally irrigation helps to suppress weed growing in rice fields. In contrast, agriculture that relies only on direct rainfall is sometimes referred to as dryland farming or as rain fed farming. Environmental problems such depletion of underground aquifers, ground subsidence, buildup of toxic salts on soil surface in areas of high evaporation, overirrigation and the possibility of water pollution.
Robert Marshall (January 2, 1901 – November 11, 1939) was an American forester, writer and wilderness activist who is best remembered as the person who spearheaded the 1935 founding of the Wilderness Society in the United States. Marshall developed a love for the outdoors as a young child. He was an avid hiker and climber who visited the Adirondack Mountains frequently during his youth, ultimately becoming one of the first Adirondack Forty-Sixers. He also traveled to the Brooks Range of the far northern Alaskan wilderness. He wrote numerous articles and books about his travels, including the bestselling 1933 book Arctic Village.
A scientist with a PhD in plant physiology, Marshall became independently wealthy after the death of his father in 1929. He had started his outdoor career in 1925 as forester with the U.S. Forest Service. He used his financial independence for expeditions to Alaska and other wilderness areas. Later he held two significant public appointed posts: chief of forestry in the Bureau of Indian Affairs, from 1933 to 1937, and head of recreation management in the Forest Service, from 1937 to 1939, both during the administration of President Franklin D. Roosevelt. During this period, he directed the promulgation of regulations to preserve large areas of roadless land that were under federal management. Many years after his death, some of those areas were permanently protected from development, exploitation, and mechanization with the passage of the Wilderness Act of 1964. (Full article...)
The European Centre for Nature Conservation (ECNC) was a Dutch non-profit foundation which was active in the field of European nature and biodiversity policy between 1993 and 2017. It was set up as a network of university departments, expert centres and government agencies and operated as a European biodiversity expertise centre. The organization promoted sustainable management of natural resources and biodiversity, and aimed to stimulate interaction between science, society and policy.

"The Wildlife Enforcement Monitoring System will provide the platform for our enforcement agencies to collect and share information on the trends and patterns of wildlife crime. Moreover, the cross-border nature of wild life crime underscores the need to enhance cooperation among our governments and to pool financial and human resources. I am confident that these measures will go a long way in enhancing our capacity to protect our wildlife resources."
