==Ecological Footprint== en.wikipedia.org/wiki/Ecological_footprint Ecological footprint analysis approximates the amount of arable and agriculturally or ecologically productive land area it takes to sustain one human or group of humans, say in a family or city, based on their use of energy, food, water, building material and other consumables. It is a way of determining relative consumption for the purpose of educating people about their resource use and, sometimes, triggering them to change how they consume.
==Renewable Resources== http://www.rnrf.org/ The International Society of Arboriculture is a worldwide professional, scientific, and educational organization dedicated to fostering a greater appreciation for trees and to promoting research, technology, and the professional practice of arboriculture. The society is a dynamic medium through which arborists around the world share their experience and knowledge for the benefit of society.
==Environmental Sustainability== http://sedac.ciesin.columbia.edu/es/esi/ This website provides access to the 2005 Environmental Sustainability Index (ESI) report and underlying data. In addition, it provides an archive of the reports and data for the 2000, 2001, and 2002 versions of the ESI. The documents made available here provide in-depth details on the analytical framework, quantitative methodology, and data sources that underlie each edition of the ESI.
==Sustainable Development== http://www.un.org/esa/sustdev/natlinfo/natlinfo.htm National information includes information submitted annually in national reports by member States to the Commission on Sustainable Development. Also included are 2002 Country Profiles and 2002 National Assessment Reports prepared for the Johannesburg World Summit, as well as 1997 Country Profiles prepared for the Five-Year Review of the Earth Summit.
==Environmentalism== http://en.wikipedia.org/wiki/Environmentalism It is a social movement which seeks to influence the political process by lobbying, education, activism and setting an example in order to protect natural resources and ecosystems. Some of the issues of concern for the environmental movement are pollution, species extinction, waste reduction, recycling, the threat of global warming and ozone depletion, and genetically engineered foods.
==Emission Reduction Credits== http://www.dec.state.ny.us/website/dar/boss/ercindex.html The Bureau of Stationary Sources maintains a registry of Emission Reduction Credits (ERCs) that are available for offsets pursuant to the New York State Clean Air Compliance Act and 6NYCRR Subpart 231-2.
==Environmental Ethics== http://en.wikipedia.org/wiki/Environmental_impact_statement According to the National Environmental Policy Act (NEPA) whenever the U.S. Federal Government takes a "major Federal action significantly affecting the quality of the human environment" it must first consider the environmental impact in a document called an Environmental Impact Statement (EIS).
==Earth Day== http://www.earthsite.org/day.htm And so it came to pass we initiated the celebration of Earth Day on March 21, 1970. The first Proclamation of Earth Day was by San Francisco, the City of Saint Francis, patron saint of ecology. Designating the First Day of Spring, March 21, 1970 to be Earth Day, this day of nature's equipoise was later sanctioned in a Proclamation signed by Secretary General U Thant at the United Nations where it is observed each year. Earth Day was firmly established for all time on a sound basis as an annual event to deepen reverence and care for life on our planet.
==Chernobyl== http://en.wikipedia.org/wiki/Chernobyl_accident The Chernobyl accident occurred on April 26, 1986, at the Chernobyl nuclear power plant (originally named after Vladimir Lenin) in Ukraine (then part of the Soviet Union). It is regarded as the worst accident in the history of nuclear power, producing (due to a lack of a full containment building) a plume of radioactive debris that drifted over parts of the western Soviet Union, Eastern Europe, Scandinavia, UK, and eastern US. Large areas of Ukraine, Belarus, and Russia were badly contaminated, resulting in the evacuation and resettlement of roughly 200,000 people. About 60% of the radioactive fallout landed in Belarus.
