location of discoveries in the human fossil record. Almost all of China's important geological discoveries are now published in English as this allows access to more prestigious international journals. China Geological Survey The China Geological Survey (CGS) was founded in 1915. However, it was disbanded after the Chinese Civil War and only reinstated in 1999. During this time geological exploration and natural hazard mitigation was performed by other government departments. The CGS supplies information to international cooperations and disseminates public geoscience knowledge and information to promote the sustainable development of China's natural resources. The CGS also works internationally on mineral exploration and geological research. About 28% of the CGS published research is in collaboration with international researchers, which is comparable to that of the United States Geological Survey. The CGS has also been involved in environmental research in China. This has included the 2013 findings that 90% of Chinese cities had "polluted" groundwater, and about 66% have "severely polluted" groundwater. The CGS can be seen as part of China's use of international soft power as it attempts to gain access to foreign minerals. Geological parks China has 44 national geological parks managed since 1999 by the Chinese Ministry of Land and Resources in cooperation with UNESCO to find a way to protect geological sites of importance while encouraging both tourism and scientific research. Zhangjiajie Gritstone-peak Forest, China's best preserved cluster of volcanoes and geological features in Hunan Province, in 2001 became among the first nationally designated geological park. In February 2004, UNESCO announced the World Network of Geological Parks as well as its first geology park conference to be held in Beijing from June 27–29, 2004. Of the 28 original UNESCO World Geoparks, eight are in China. Currently there 26 World Geoparks in China. These include the Shilin Geopark in China's Yunnan Province, featuring a carbonate peak forest landform, which brings about the formation of various karst landscapes, such as stone teeth, corroded gullies and corroded funnels. The Huangshan Geopark in Anhui Province, famed for its grand and steep mountains, with 72 peaks of over 1,000 meters high. The geopark is picturesque with green and straight pines, jagged rocks of grotesque shapes, wide and imposing cloud sea, as well as many gushing warm springs. Other world-class Chinese geology parks include Lushan Geopark in Jiangxi Province, Yuntaishan Geopark and Songshan Geopark in central China's Henan Province, Danxia Geopark in Guangdong, Zhangjiajie
