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.

Kissimmee River restoration from the air
The restoration of the Everglades is an ongoing effort to remedy damage inflicted on the environment of southern Florida during the 20th century. It is the most expensive and comprehensive environmental repair attempt in history.

The degradation of the Everglades became an issue in the United States in the early 1970s after a proposal to construct a jetport in the Big Cypress Swamp. Studies indicated the airport would have destroyed the ecosystem in South Florida and Everglades National Park. After decades of destructive practices, both state and federal agencies are looking for ways to balance the needs of the natural environment in South Florida with urban and agricultural centers that have recently and rapidly grown in and near the Everglades.

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.

Map of countries by population density.

Overpopulation is one of the reasons given for environmental impact as given by Paul R. Ehrlich's formula I = P x A x T where I is the impact, P is population A is affluence and T is technology. (See also:List of countries by population density.)

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:
