Environment

Introduction

Land management has preserved the natural characteristics of Hopetoun Falls, Australia while allowing ample access for visitors.

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 the 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, atmosphere, and natural phenomena that occur within their boundaries and their nature.
  • Universal natural resources and physical phenomena that lack clear-cut boundaries, such as air, water, and climate, as well as energy, radiation, electric charge, and magnetism, not originating from civilized human actions.

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.

biophysical environment is a biotic and abiotic surrounding of an organism or population, and consequently includes the factors that have an influence in their survival, development, and evolution. A biophysical environment can vary in scale from microscopic to global in extent. It can also be subdivided according to its attributes. Examples include the marine environment, the atmospheric environment and the terrestrial environment. The number of biophysical environments is countless, given that each living organism has its own environment.

The term environment can refer to a singular global environment in relation to humanity, or a local biophysical environment, e.g. the UK’s Environment Agency. (Full article…)

Radium Hill, a former minesite in South Australia which operated from 1906 until 1961. It was Australia’s first uranium mine, years before the country’s next major mines at Rum Jungle in the Northern Territory (opened in 1950), and the Mary Kathleen mine in Queensland (1958).

Nuclear weapons testing, uranium mining and export, and nuclear power have often been the subject of public debate in Australia, and the anti-nuclear movement in Australia has a long history. Its origins date back to the 1972–1973 debate over French nuclear testing in the Pacific and the 1976–1977 debate about uranium mining in Australia.

Several groups specifically concerned with nuclear issues were established in the mid-1970s, including the Movement Against Uranium Mining and Campaign Against Nuclear Energy (CANE), cooperating with other environmental groups such as Friends of the Earth and the Australian Conservation Foundation. The movement suffered a setback in 1983 when the newly elected Labor Government failed to implement its stated policy of stopping uranium mining. But by the late 1980s, the price of uranium had fallen, the costs of nuclear power had risen, and the anti-nuclear movement seemed to have won its case; CANE was disbanded in 1988. (Full article…)

The carbon cycle is the biogeochemical cycle by which carbon is exchanged between the biosphere, geosphere, hydrosphere, and atmosphere of the Earth. Burning fossil fuels leads to the addition of extra carbon into the cycle over what naturally occurs and is a major cause of climate change.

Robert Sterling Yard in Yosemite National Park, 1920

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…)

The California Air Resources Board (CARB or ARB) is the “clean air agency” of the government of California. Established in 1967 when then-governor Ronald Reagan signed the Mulford-Carrell Act, combining the Bureau of Air Sanitation and the Motor Vehicle Pollution Control Board, CARB is a department within the cabinet-level California Environmental Protection Agency.

The stated goals of CARB include attaining and maintaining healthy air quality; protecting the public from exposure to toxic air contaminants; and providing innovative approaches for complying with air pollution rules and regulations. CARB has also been instrumental in driving innovation throughout the global automotive industry through programs such as its ZEV mandate. (Full article…)

Elizabeth I of England

The use of sea and air is common to all; neither can a title to the ocean belong to any people or private persons, forasmuch as neither nature nor public use and custom permit any possession therof.
