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

Francisco Alves Mendes Filho (December 15, 1944 – December 22, 1988), also known as Chico Mendes, was a Brazilian rubber tapper, unionist and environmental activist. He fought to stop the logging of the Amazon Rainforest to clear land for cattle ranching, and founded a national union of rubber tappers in an attempt to preserve their profession and the rainforest that it relied upon. He was murdered in 1988 by ranchers opposed to his activism.

On 22 December 1988, Mendes was assassinated by gunshot at his Xapuri home. In December, 1990 rancher Darcy Alves Pereira and his son Darli Alves were sentenced to 19 years in prison for their part in Mendes' assassination.

Selected organization

Intergovernmental Panel on Climate Change
The Intergovernmental Panel on Climate Change (IPCC) is a scientific intergovernmental body tasked to evaluate the risk of climate change caused by human activity. The panel was established in 1988 by the World Meteorological Organization (WMO) and the United Nations Environment Programme (UNEP), two organizations of the United Nations. The IPCC shared the 2007 Nobel Peace Prize with former Vice President of the United States Al Gore.

One of the main activities of the IPCC is to publish special reports on topics where it supports the UN Framework Convention on Climate Change (UNFCCC), which is essentially the document behind the Kyoto Protocol. It bases its assessment mainly on peer reviewed and published scientific literature. The IPCC is only open to member states of the WMO and UNEP.

The stated aims of the IPCC are to assess scientific information relevant to:

  1. Human-induced climate change,
  2. The impacts of human-induced climate change,
  3. Options for adaptation and mitigation.

The IPCC does not carry out research, nor does it monitor climate or related phenomena. A main activity of the IPCC is publishing special reports on topics relevant to the implementation of the UN Framework Convention on Climate Change (UNFCCC), an international treaty that acknowledges the possibility of harmful climate change; implementation of the UNFCCC led eventually to the Kyoto Protocol. The IPCC bases its assessment mainly on peer reviewed and published scientific literature. The IPCC is only open to member states of the WMO and UNEP.

IPCC reports are widely cited in almost any debate related to climate change. National and international responses to climate change generally regard the UN climate panel as authoritative. The summary reports (i.e. Summary for Policymakers), which draw the most media attention, include review by participating governments in addition to scientific review.
