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.
Pollution can affect the atmosphere, more specifically the Ozone layer, because CFC's (chlorofluorocarbons) and other chemicals react with the Ozone (O3) and turn into Chlorin â¦ e monoxide (ClO) and an oxygen molecule (O2) which then starts the deterioration of the Ozone layer.he main effect of carbon pollution (that is, carbon dioxide  emissions) on the atmosphere is to trap heat.
