Introduction

A 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.

Crown-of-thorns starfish in Fiji
The Great Barrier Reef is the world's largest coral reef system, composed of roughly 3,000 individual reefs and 900 islands that stretch for 2,600 kilometres (1,616 mi) and cover an area of approximately 344,400 km². The reef is located in the Coral Sea, off the coast of Queensland in northeast Australia. A large part of the reef is protected by the Great Barrier Reef Marine Park.

The Great Barrier Reef's environmental pressures include lowered water quality from runoff including suspended sediment, excess nutrients, pesticides, and fluctuations in salinity. The effects of climate change, including increased temperatures, storms and coral bleaching. Cyclic outbreaks of the crown-of-thorns starfish, overfishing which disrupts food chains, and shipping routes which can result in oil spills or improper ballast discharge also damage the reef.

Selected biography

Apron diagram.png
Arne Dekke Eide Næss (born January 27, 1912) is widely regarded as the foremost Norwegian philosopher of the 20th century, and is the founder of deep ecology. His philosophical work focused on Spinoza, Buddhism and Gandhi. Næss combined his ecological vision with Gandhian nonviolence and on several occasions participated in direct action. In 1970, together with a large number of demonstrators, he chained himself to rocks in front of Mardalsfossen, a waterfall in a Norwegian fjord, and refused to descend until plans to build a dam were dropped. Though the demonstrators were carried away by police and the dam was eventually built, the demonstration launched a more activist phase of Norwegian environmentalism.

Næss had been a minor political candidate for the Norwegian Green Party and in 1939 he was the youngest person to be appointed full professor at the University of Oslo and the only professor of philosophy in the country at the time. In 1996, he won the Swedish Academy Nordic Prize, known as the 'little Nobel'. In 2005 he was decorated as a Commander with Star of the Royal Norwegian Order of St. Olav for socially useful work.

Recycling is the reprocessing of materials into new products. Recycling prevents useful material resources being wasted, reduces the consumption of raw materials and reduces energy usage, and hence greenhouse gas emissions, compared to virgin production.

Selected organization

Logo for Green Peace
Greenpeace, originally known as the Greenpeace Foundation, is an international environmental organization founded in Vancouver, British Columbia, Canada, in 1971. It is best known for its campaigns against nuclear weapons and campaigning against whaling. In later years, the focus of the organization turned to other environmental issues, including bottom trawling, global warming, ancient forest destruction, nuclear power, and genetic engineering. Greenpeace uses direct action, lobbying and research to achieve its goals. Greenpeace has national and regional offices in 46 countries worldwide, all of which are affiliated to the Amsterdam-based Greenpeace International.

The global organization receives its income through the individual contributions of an estimated 3 million financial supporters, as well as from grants from charitable foundations, but does not accept funding from governments or corporations. It is often the subject of criticism and ridicule for supposedly over-the-top protesting.

On its official website, Greenpeace defines its mission as the following:
