【明報專訊】HONG KONG has again been featured on the cover of an international magazine. That, alas, is not a good piece of news. Its glittering night view is on the cover of a special on light pollution of Sky & Telescope, an authoritative international astronomy magazine. Hong Kong should not and cannot become a pitch-dark fishing village again. However, the idea of "extensive development" that brightly lit streets represent prosperity is already out. Now societies aim at balanced and sustained development. The government should hasten to obtain legislation for tackling light pollution so that people whose flats are near big billboards can get to sleep and so that power consumption will come down. This is what citizens want the government to do and what it is duty-bound to do.
