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.

The Northwest Exelon Pavilion is the Millennium Park Welcome Center and houses the park's office
The Exelon Pavilions are four buildings that generate electricity from solar energy and provide access to underground parking in Millennium Park in the Loop community area of Chicago in Cook County, Illinois, United States. The Northeast Exelon Pavilion and Northwest Exelon Pavilion (jointly the North Exelon Pavilions) are located on the northern edge of the park along Randolph Street, and flank the Harris Theater. The Southeast Exelon Pavilion and Southwest Exelon Pavilion (jointly the South Exelon Pavilions) are located on the southern edge of the park along Monroe Street, and flank the Lurie Garden. Together the pavilions generate 19,840 kilowatt-hours ([convert: unknown unit]) of electricity annually, worth about $2,350 per year.

The four pavilions, which cost $7 million, were designed in January 2001; construction began in January 2004. The South Pavilions were completed and opened in July 2004, while the North Pavilions were completed in November 2004, with a grand opening on April 30, 2005. The North Pavilions have received the Leadership in Energy and Environmental Design (LEED) silver rating from the United States Green Building Council, as well as an award from the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE).

Selected biography

Nobel Prize 2009-Press Conference KVA-30.jpg
Elinor Ostrom (August 7, 1933 – June 12, 2012), an American political economist, was awarded the 2009 Sveriges Riksbank Prize in Economic Sciences in Memory of Alfred Nobel for "her analysis of economic governance, especially the commons". She was the first, and to date, the only woman to win the prize in this category.

In 1973, she co-founded the Workshop in Political Theory and Policy Analysis at Indiana University. Examining the use of collective action, trust, and cooperation in the management of common pool resources, her approach to public policy, known as the institutional analysis and development (IAD) framework, has been considered sufficiently distinct to be thought of as a separate school of public choice theory.

Her most famous research focuses on how humans interact with ecosystems to maintain long-term sustainable resource yields. She conducted her field studies on the management of pasture by locals in Africa and irrigation systems management in villages of western Nepal. Her work has considered how societies have developed diverse institutional arrangements for managing natural resources and avoiding ecosystem collapse in many cases, even though some arrangements have failed to prevent resource exhaustion. Her work emphasized the multifaceted nature of human–ecosystem interaction and argues against any singular "panacea" for individual social-ecological system problems.

Mai Po Marshes is a nature reserve in Hong Kong. It is managed by World Wide Fund for Nature. The marshes have an area of about 1800 acres and is listed as a Ramsar site under Ramsar Convention in 1995. It provides a conservation area for mammals, reptiles, insects, and over 350 kinds of birds (including Saunders's Gull and a quarter of world's Black-faced Spoonbill population). It also has inter-tidal mangroves along with 24 traditionally operated shrimp ponds (called Gei Wai locally) to provide food for the birds. It receives 40,000 visitors annually.

Selected organization

The Sierra Club is an environmental organization in the United States. It was founded on May 28, 1892, in San Francisco, California, by the Scottish-American preservationist John Muir, who became its first president. The club was one of the first large-scale environmental preservation organizations in the world, and currently engages in lobbying politicians to promote environmentalist policies. Recent focuses of the club include promoting sustainable energy, mitigating global warming, and opposing the use of coal. The club is known for its political endorsements, which are often sought after by candidates in local elections; it generally supports liberal and progressive candidates in elections.
