In the United States today, the organized environmental movement is represented by a wide range of organizations sometimes called non-governmental organizations or NGOs. These organizations exist on local, national, and international scales. Environmental NGOs vary widely in political views and in the amount they seek to influence the environmental policy of the United States and other governments. The environmental movement today consists of both large national groups and also many smaller local groups with local concerns. Some resemble the old U.S. conservation movement - whose modern expression is The Nature Conservancy, Audubon Society and National Geographic Society - American organizations with a worldwide influence. ==Scope of the movement== * The early Conservation movement, which began in the late 19th century, included fisheries and wildlife management, water, soil conservation and sustainable forestry. Today it includes sustainable yield of natural resources, preservation of wilderness areas and biodiversity * The modern Environmental movement, which began in the 1960s with concern about air and water pollution, became broader in scope to including all landscapes and human activities. See List of environmental issues. * Environmental health movement dating at least to Progressive Era (1890s - 1920s) urban reforms including clean water supply, more efficient removal of raw sewage and reduction in crowded and unsanitary living conditions. Today Environmental health is more related to nutrition, preventive medicine, aging well and other concerns specific to the human body's well-being. * Sustainability movement which started in the 1980s focused on Gaia theory, value of Earth and other interrelations between human sciences and human responsibilities. Its spinoff Deep Ecology was more spiritual but often claimed to be science. * Environmental justice is a movement that began in the U.S. in the 1980s and seeks an end to environmental racism. Often, low-income and minority communities are located close to highways, garbage dumps, and factories, where they are exposed to greater pollution and environmental health risk than the rest of the population. The Environmental Justice movement seeks to link "social" and "ecological" environmental concerns, while at the same time keeping environmentalists conscious of the dynamics in their own movement, i.e. racism, sexism, homophobia, classicism, and other malaises of dominant culture. As public awareness and the environmental sciences have improved in recent years, environmental issues have broadened to include key concepts such as "sustainability" and also new emerging concerns such as ozone depletion, global warming, acid rain, land use and biogenetic pollution. Environmental movements often interact or are linked with other social movements, e.g. for peace, human rights, and animal rights; and against nuclear weapons and/or nuclear power, endemic diseases, poverty, hunger, etc. Some US colleges are now going green by signing the "President's Climate Commitment," a document that a college President can sign to enable said colleges to practice environmentalism by switching to solar power, etc.〔http://www.presidentsclimatecommitment.org/〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Environmental movement in the United States」の詳細全文を読む スポンサード リンク
