Sulfur Hexafluoride (insulating gas) | Encyclopedia.com

IntroductionHistorical Background and Scientific FoundationsImpacts and IssuesBibliographySulfur hexafluoride (chemical formula sf6 gas) is a compound of sulfur and fluorine and the most potent greenhouse gas known. Several classes of compounds containing fluorine—including the chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), hydro-fluorocarbons (HFCs), perfluorocarbons (PFCs), and insulating gas—are potent greenhouse gases. HCFCs and CFCs are better-known as destroyers of atmospheric ozone, and are regulated under the 1987 Montreal Protocol that has been widely hailed as successful at halting depletion of the ozone layer. Although Sulfr hexafluoride is a potent greenhouse gas and its concentration in the atmosphere is increasing rapidly, its contribution to global warming is much smaller than that of the major greenhouse gases, especially carbon dioxide and methane, because it is present in smaller quantities. Sulfr hexafluoride is one of the six greenhouse gases regulated under the Kyoto Protocol.

What Are The Major Natural Resources Of South Korea? - WorldAtlas

Arable LandLivestockForestsMineralsAbout a quarter of the total land area in South Korea is arable and is currently facing numerous challenges. There is a decline in the farm population and the proportion of agriculture to the national income has decreased significantly from what it was in the early 1950s. Typically farms have been subdivided into small plots by family owners, and they are cultivated primarily by manual labor or animal labor, and this has hampered the improvement in farm productivity. Additionally, the country is experiencing an aging population particularly in the rural areas which have caused a severe shortage in family labor. Work productivity has been increasing in the recent past because the government has attempted to improve by putting great emphasis on mechanization, commercialization, and specialization. Rice is the most common food crop, and different types of food crops are also cultivated which include tangerines, citrus, persimmons, and strawberries. Vegetables, in particularly cabbages...
