Environment

Devil's Punchbowl Waterfall, New Zealand.
The natural environment comprises all naturally occurring surroundings and conditions in which living things grow and interact on Earth. These include complete landscape units that function as natural systems without major human intervention, as well as plants, animals, rocks, and natural phenomena occurring within their boundaries. They also include non-local or universal natural resources that lack clear-cut boundaries, such as air, water and climate.

The concept of the natural environment can be distinguished by components:

As human population numbers increase and as humans continue to evolve, human activity modifies the natural environment at a rapidly increasing rate, producing what is referred to as the built environment. The potential of the natural environment to sustain these anthropogenic changes while continuing to function as an ecosystem is an issue of major worldwide concern. Key environmental areas of interest include climate change, water supply and waste water, air pollution, waste management and hazardous waste, and land use issues such as deforestation, desertification, and urban sprawl.

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 (67,697 MBtu) 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

Gro Brundtland
Gro Harlem Brundtland (born April 20, 1939) is a Norwegian politician, diplomat, and physician, and an international leader in sustainable development and public health. She is a former Prime Minister of Norway, and has served as the Director General of the World Health Organization. She now serves as a Special Envoy on Climate Change for the United Nations Secretary-General Ban Ki-moon.

She is most famous for chairing the World Commission on Environment and Development (WCED), widely referred to as the Brundtland Commission, developing the broad political concept of sustainable development in the course of extensive public hearings that were distinguished by their inclusiveness and published its report Our Common Future in April 1987. The Brundtland Commission provided the momentum for the 1992 Earth Summit/UNCED, that was headed by Maurice Strong, who had been a prominent member of the Brundtland Commission. The Brundtland Commission also provided momentum for Agenda 21.

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.

Selected organization

The Brundtland Commission, formally the World Commission on Environment and Development (WCED), known by the name of its Chair Gro Harlem Brundtland, was convened by the United Nations in 1983. The commission was created to address growing concern "about the accelerating deterioration of the human environment and natural resources and the consequences of that deterioration for economic and social development." In establishing the commission, the UN General Assembly recognized that environmental problems were global in nature and determined that it was in the common interest of all nations to establish policies for sustainable development.

The Report of the Brundtland Commission, Our Common Future, was published in 1987. It was welcomed by the General Assembly in its resolution 42/187. The report deals with sustainable development and the change of politics needed for achieving that. The definition of this term in the report is quite well known and often cited:

"Sustainable development is development that meets the needs of the present without compromising the ability of future generations to meet their own needs. It contains within it two key concepts:
  • the concept of 'needs', in particular the essential needs of the world's poor, to which overriding priority should be given; and
  • the idea of limitations imposed by the state of technology and social organization on the environment's ability to meet present and future needs."

Selected quote

I'd like to share a revelation that I've had during my time here. It came to me when I tried to classify your species. I realized that you humans are not actually mammals. Every mammal on this planet instinctively develops a natural equilibrium with the surrounding environment, but you humans do not. You move to an area, and you multiply and multiply, until every natural resource is consumed. The only way you can survive is to spread to another area. There is another organism on this planet that follows the same pattern. Do you know what it is? A virus. Human beings are a disease, a cancer of this planet.
