Human beings have been concerned about nature and their place in it for millennia. Disquiet about the consequences of human action on the natural environment date back to the ancient Greeks and Romans. The efforts of the green movement can be traced back to the 19th century. In this period, individuals, groups, and organizations began campaigning for the conservation and preservation of natural areas and the protection of wildlife species. Efforts to combat pollution also began. It was not until the 1960s, however, that the green movement in its more modern incarnation emerged. The green movements that arose at this time maintained the concerns with conservation, preservation, and industrial pollution held by earlier generations, but added to their agenda new issues, including justice, equality, participatory democracy, and sustainability.The A to Z of the Green Movement provides a detailed and comprehensive overview of green parties and movements, green issues, and green concepts. This is done through a chronology, an introductory essay, a bibliography, and hundreds of cross-referenced dictionary entries on countries in the world where green parties or proto-parties have formed, green movement organizations, major international environmental conferences, and green concepts. This useful reference will be greatly valued by students, academics, journalists, and policymakers alike.
