They have good reasons to stand alongside Pan.The latest round of haze(雾霾) reduced visibility to under 500 meters in many parts of the city.The smog has also led to a great increase in respiratory illnesses,particularly among children and the elderly.Anxious parents and doctors about all blame the smoggy air for the illnesses.Though most schoolchildren are home for the winter holidays,the bad air can easily move indoors.Besides,ordinary medical masks fail to provide adequate protection,so some people have turned to gas masks and respirators(呼吸器).
The causes of the scary smog are rather mysterious,though experts blame excessive emissions and the mountains around Beijing that trap pollution in winter,unless there is adequate wind to clear it away.Some critics have pointed fingers at China’s top two oil firms,China National Petroleum Corp and China Petrochemical Corporation,saying the companies’ outdated production technologies produce large quantities of substandard,highpolluting gas fuel.
Meanwhile,concerned Beijingers have moved their brainstorming sessions to cyberspace.If Pan’s proposal for a Clean Air Act is adopted,netizens say the new law should include items providing for “carfree days” in times of smog,higher standards for vehicle fuel,stricter restrictions on industrial and exhaust gas emissions,and more effective protection for the public.
Beijing is not the only city that has ever lost the blue sky.Five days of thick fog caused thousands of deaths in Britain in December 1952,urging the government to pass the first Clean Air Act in 1956,which introduced smokeless zones and cleaner fuels to reduce pollution.That may provide some experience for Beijing to refer to.
