misuse of science. The United Nations and its and educational, scientific, and cultural branch, UNESCO, heir to the League's International Committee on Intellectual Cooperation, both founded in 1945 to do a better job at peace-keeping and cooperation, were at first hindered by the Cold War. As it manifestly drew to an end in the 1970's, and the countries of east Europe would be open once more, UNESCO began to be more effective, formulating organizations to respond to a growing demand for the protection of the heritage that was left. The current round of innovation to which geo-park belongs dates to the last decades of the 20th century and the first of the 21st, although it may not be over yet. They began as marketing terms in the vending of what Farsani calls "sustainable tourism," characterizing it as "a new niche market," the key words being, in addition to geopark, geotourism, geoheritage, geosite, geoconservation, and geodiversity. It is not possible to discover what individuals first innovated the words. Authors such as Farsani can only state the groups among which they were thought to be first current. The term “geopark” was apparently first used to describe a newly instituted park in the west Vulkaneifel district of the Eifel Mountains of Rhineland-Palatinate, Germany. The region had tended to be economically depressed due to the preference of buyers and sellers for markets in nearby France. They did have a noted geological asset: a now dormant forested volcanic range. The land shows evidence of ancient volcanos, including crater lakes, mineral springs, and pipe formations. The place also abounds in fossils. Although of interest to scientists and hikers, the terrain was generally regarded as a liability, some 19th-century plans even having been made to fill lakes. Types of geopark The word geopark is no longer open to the process of innovation through word production. It has been defined by various organizations in the field of earth science. An essential element of the definition is that a geopark must be branded as part of an international geopark network. A national park is not necessarily a geopark. For example, the United States has a system of national parks, but none of them are geoparks. Canada, on the other hand, has several. A geopark network requires the branding of an international scientific association. They only brand protected areas that meet certain standards, as presented above. The branding has no
