Ronald Ling Pak-ki, 20,  University of Hong Kong
The  Symphony of Lights is a nightly synchronised light, laser and music show  which includes buildings  on both sides of the Victoria Harbour. 
This multimedia display is recognised as the world's 'largest permanent light-and-sound show' by the Guinness World Records.
It is one of Hong Kong's biggest attractions and  is  popular among tourists. But it is definitely not necessary to have this show every night. It involves 44 buildings in both Kowloon and on Hong Kong Island. One can imagine how much electricity is used up producing such a  spectacular light show. It is definitely a waste of energy to have the show every night. 
It totally goes against the trend of creating a greener city. To have such a non-eco-friendly show running every day is not good for our city's image.
In addition to the high energy consumption, the show might not have a real impact on attracting tourists. Forbes magazine referred to the show as  being part of  the Lunar New Year celebrations. 
 I don't think it is necessary to organise this 10-minute show every night to highlight the vibrancy of the beautiful Victoria harbour. 
Tourists will not choose Hong Kong as a destination simply because of this show. We are already well-known for our spirit and cultural diversity. What Hong Kong really needs to do to strengthen its tourism industry is to improve the living environment and quality of services - not hold a daily  Symphony of Lights show.
Elaine Yu Yee-nee, 15, Creative Secondary School
Hong Kong is regarded by many as 'the Pearl of the Orient'. It is one of the most prosperous cities in the world. 
A lot of people believe the Symphony of Lights show is a vibrant addition to Hong Kong's list of excellent tourist attractions. With its coloured lights and laser beams, they say the display offers a stunning night view of Victoria harbour.  
The appeal of the show - and the interest it generates around the world - helps to boost the economy of Hong Kong. It lets people know about Hong Kong and shows that it is a lovely and exciting place to travel to and to live in. 
 The Symphony of Lights certainly played a part in the revenue generated by the city's tourism industry last year.  
On average,  the length of overnight visits by tourists  increased from 3.2 nights in 2009 to 3.6nights  in 2010. Also, spending by each overnight visitor rose to an average of  HK$6,728 last year.
Some people may argue that this show can cause light pollution. But it lasts only 10minutes - and starts at 8pm. 
I think very few residents who live near the harbour will be sleeping at that time. On the contrary, they can watch this fabulous show while having their dinner!
To ensure Hong Kong's continued growth,  there is a need for the Symphony of Lights to take place every night.



Is it necessary for Hong Kong to have the 'Symphony of Lights' every night?
