'Light Pollution' in our future?

Hong Kong already suffers from it now, i.e., 'light pollution'. With the growing habit of installing decorative multi-colored LED on our buildings, would we end up like HK? I don't suppose our planners pay attention to this and so it will creep up on us gradually especially when each developer try to out do each other. It is the same desire in the past when each leading tycoon wanted to out do each other with the tallest office tower until the government put a stop to it. This government is no longer as in the loop or on the ball as before. Now if the problem of 'light population' befalls us I will dig out this post to reflect upon.
