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.

The Deepwater Horizon oil spill (also referred to as the "BP oil spill") was an environmental disaster which began on 20 April 2010, off the coast of the United States in the Gulf of Mexico on the BP-operated Macondo Prospect, considered the largest marine oil spill in the history of the petroleum industry and estimated to be 8 to 31 percent larger in volume than the previous largest, the Ixtoc I oil spill, also in the Gulf of Mexico. Caused in the aftermath of a blowout and explosion on the Deepwater Horizon oil platform, the United States federal government estimated the total discharge at 4.9 MMbbl (210,000,000 US gal; 780,000 m3). After several failed efforts to contain the flow, the well was declared sealed on 19 September 2010. Reports in early 2012 indicated that the well site was still leaking. The Deepwater Horizon oil spill is regarded as one of the largest environmental disasters in world history.
A massive response ensued to protect beaches, wetlands and estuaries from the spreading oil utilizing skimmer ships, floating booms, controlled burns and 1,840,000 US gal (7,000 m3) of oil dispersant. Due to the months-long spill, along with adverse effects from the response and cleanup activities, extensive damage to marine and wildlife habitats and fishing and tourism industries was reported. In Louisiana, oil cleanup crews worked four days a week on 55 mi (89 km) of Louisiana shoreline throughout 2013. 4,900,000 lb (2,200 t) of oily material was removed from the beaches in 2013, over double the amount collected in 2012. Oil continued to be found as far from the Macondo site as the waters off the Florida Panhandle and Tampa Bay, where scientists said the oil and dispersant mixture is embedded in the sand. In April 2013, it was reported that dolphins and other marine life continued to die in record numbers with infant dolphins dying at six times the normal rate. One study released in 2014 reported that tuna and amberjack exposed to oil from the spill developed deformities of the heart and other organs which would be expected to be fatal or at least life-shortening; another study found that cardiotoxicity might have been widespread in animal life exposed to the spill.

Robert Sterling Yard (February 1, 1861 – May 17, 1945) was an American writer, journalist, and wilderness activist. Born in Haverstraw, New York, Yard graduated from Princeton University and spent the first twenty years of his career in the editing and publishing business. In 1915, he was recruited by his friend Stephen Mather to help publicize the need for an independent national park agency. Their numerous publications were part of a movement that resulted in legislative support for a National Park Service (NPS) in 1916. Yard served as head of the National Parks Educational Committee for several years after its conception, but tension within the NPS led him to concentrate on non-government initiatives. He became executive secretary of the National Parks Association in 1919.
Yard worked to promote the national parks as well as educate Americans about their use. Creating high standards based on aesthetic ideals for park selection, he also opposed commercialism and industrialization of what he called "America's masterpieces". These standards subsequently caused discord with his peers. After helping to establish a relationship between the NPA and the United States Forest Service, Yard later became involved in the protection of wilderness areas. In 1935, he became one of the eight founding members of The Wilderness Society and acted as its first president from 1937 until his death eight years later. Yard is now considered an important figure in the modern wilderness movement. (Full article...)
Seacology is a nonprofit501(c)(3) charitable organization headquartered in Berkeley, California, that works to preserve island ecosystems and cultures around the world. Founded in 1991, it began with the work of ethnobotanistPaul Alan Cox, who researched tropical plants and their medicinal value in the village of Falealupo in Samoa during the mid-1980s. When the villagers were pressured into selling logging rights to their rainforest in 1988 to build a new school, Cox and his wife offered to help secure funds for the new school in return for an agreement with the villagers to protect their forest. With the help of his friends and family, Cox secured the funds within six months, later earning him and the village chief, Fuiono Senio, the Goldman Environmental Prize for their efforts. Word spread throughout the islands, and with increasing demand for similar projects, Cox, along with Bill Marré and Ken Murdock, decided to form Seacology and expand their work internationally. For the first few years, the organization operated on a volunteer basis.
Because of the high risk of extinction for island fauna and the decline in coral reef ecosystems, Seacology's primary focus is projects in which villagers sign contracts under which they agree to help protect either terrestrial or marine habitat for a specified time in return for new buildings or services. The operations are low-cost, averaging around US$20,000 to $25,000. Construction is done with local labor and sometimes without the use of machinery. Seacology selects its projects by reviewing the recommendations of its field representatives and its scientific advisory board. (Full article...)

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.
