This is Nathan Road aglow with neon lights at night. It is the ever bustling thoroughfare on Kowloon Peninsula, Hong Kong. The only time that I have known in my life when Nathan Road is uneasily silent was during the outbreak of SARS, the epidemic desease that took over three hundred lives here, in 2003. Now Nathan Road has retained its lustre and literally shone all night long. But then shining around the clock is also known as, unflatteringly, light pollution. This could probably be an issue in most cosmospolitans. When the Lord created the world, He said, "Let there be light." Well, should we say, let there be no light at night.
