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 those in which humans have fundamentally transformed landscapes such as in urban settings and agricultural land conversion. Even in acts that seem less extreme, such as building a mud hut or a photovoltaic system in the desert, the modified environment is considered artificial. 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 considered natural.
There are no 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 affected all natural environments including: climate change, biodiversity loss and pollution from plastic and other chemicals in the air and water. More precisely, considering the different aspects or components of an environment, it becomes apparent that their degree of naturalness is not uniform. For instance, in an agricultural field, the mineralogic composition is quite similar to that of undisturbed forest soil while the structure is quite different. (Full article...)
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 2022, created 6.4 million tonnes of food waste (95kg or £250 per person); most of this was made up of salads and fresh vegetables. A majority of food waste food is avoidable,[d] with the rest being divided almost equally into foods which are unavoidable, due to being inedible (e.g. tea bags) and those that are unavoidable due to preference (e.g. bread crusts) or cooking type (e.g. potato skins).

... that every in-game environment and asset in Lego Horizon Adventures was constructed entirely from individual digital Lego bricks, meaning that they could theoretically be built in real life?
... that scholars have described the 1946 book The Failure of Technology as a precursor to the environmental movement?
It is a problem in a number of cities and it harms human health. Ground-level ozone is especially harmful for senior citizens, children, and people with heart and lung conditions such as emphysema, bronchitis, and asthma. It can inflame breathing passages, decreasing the lungs' working capacity, and causing shortness of breath, pain when inhaling deeply, wheezing, and coughing. It can cause eye and nose irritation and it dries out the protective membranes of the nose and throat and interferes with the body's ability to fight infection, increasing susceptibility to illness. Hospital admissions and respiratory deaths often increase during periods when ozone levels are high.
Mauricio González-Gordon y Díez, Marquis of Bonanza (18 October 1923 – 27 September 2013) was a Spanish sherry maker and a conservationist. Most of his life he worked for the family company, González Byass, where he increased its exports to a worldwide level. His family estate was located in the wetland region called Doñana in southern Spain and was threatened by drainage efforts in the early 1950s. González-Gordon with the help of researchers and international support managed to preserve the site, while at the same time donating some of his family land to the conservation effort. Afterward, González-Gordon became one of the founders of the Spanish Ornithological Society in 1954. His conservation efforts for Doñana culminated in the creation of the Doñana National Park in 1969. The area was designated a UNESCO World Heritage Site in 1994. (Full article...)
The Rainforest Alliance certification seal on a cup of coffee
The Rainforest Alliance is an international non-governmental organization (NGO) with staff in more than 20 countries and operations in more than 70 countries. It was founded in 1987 by Daniel Katz, an American environmental activist, who serves as the chair of the board of directors. The NGO states that its mission is "to create a more sustainable world by using social and market forces to protect nature and improve the lives of farmers and forest communities." Its work includes the provision of an environmental certification for sustainability in agriculture. In parallel to its certification program, the Rainforest Alliance develops and implements long-term conservation and community development programs in a number of critically important tropical landscapes where commodity production threatens ecosystem health and the well-being of rural communities.

A 2025 study found that for 1365 identified papers about environmental degradation, the annual number of papers increased tenfold between 2016 to 2022 A similar study found articles related to the carbon footprint of economic growth surged after 2017 (from Environmental science)
