And when it comes to price gains during the first six-years of a recovery, the current market is second to none. Between March 9, 2009 and March 9, 2015, the S&P 500 has increased by 202%. The only other market run that comes close is the postwar expansion, where the S&P returned 192% in the same time period.
Arctic Ozone Hole. CFCs Chlorofluorocarbon (CFC) is an organic compound that contains carbon, chlorine, and fluorine, produced as a volatile derivative of methane and ethane. A common subclass is the hydrochlorofluorocarbons (HCFCs), which contain hydrogen, as well.Freon is DuPont's brand name for CFCs, HCFCs and related compounds.he most common representative is dichlorodifluoromethane (R-12 or Freon-12). Chlorofluorocarbons (CFCs) are a family of chemical compounds developed back in the 1930's as safe, non-toxic, non-flammable alternative to dangerous substances like ammonia for purposes of refrigeration and spray can propellants.
So what is happening because of the CFC refrigerants is that the protective ozone layer is getting converted into incapable oxygen. Due to this the amounts of ultraviolet rays reaching the surface of the earth becomes very high and then causes excessive heating in the environment, called the greenhouse effect.hlorofluorocarbons (CFCs) have been found to cause the depletion of the ozone layer. The ozone layer prevents ultraviolet radiations of the sun from coming on the earth. This article describes the process of damaging effects of CFCs. slide 1 of 3.
