an Hour for Earth - Earth Hour

tonight is the night when earth finally gets its one hour of .... what i don't know - please ask the organizer for the answer. from 8:30 to 9:30 tonight, those who are in support of the earth hour will switch off their lights and most of their electrical equipments. i am in support.? i am not sure. i feel indifferent. but my company is. the billboards and signboards and the building lights will be turned off tonight at the mentioned time above. i wonder how many megawatt of electricity will be reduced in that one hour. why won't earth hour be expanded to nnot driving any cars or even not burning anything including smoking. for all we know earth hour is about showing support of the environment. one hour of turning off the light might reduced the amount of coal and gas burn to produce electricty so that the air will be less polluted in that one hour. what about cars? buses? trucks and smokers? they should stop too. if earth hour covers the wider horizon i am in full support. i hope that tonight i can breathe in cleaner air for one hour.
