Earthhour

Last night we participated in earthhour and switched off the lights from 8 to 9pm. Kids and dh had a steak and chips candlelight dinner during that time. (Usually kids would have their dinner earlier but it was a weekend). It wasn't so bad without the lights. The kids even practiced switching off all the lights the night before. Light is necessary for comfort and safety but do we really many lights in one focal point? Too many lights on can/will create light pollution . (Eg. I could hardly see the stars in the night sky at my home near the centre of KL because of the city's brightness... which is a pity.)
