Countries like Japan, North America, coastal China and Europe were so brightly lit at night. The more developed of the country, the brighter the sky at night and the more electricity they consumed. Hence, more and more fossil fuels have to be burnt to generate electricity to meet the increasingly power demand. Releasing too much carbon dioxide to the atmosphere will only accelerate global warming phenomenon.
I really hope that the earth will be completely in dark on 26th March 2011 at night. Let's support EARTH HOUR 2011.
