Hong Kong has long been an aviation hub for southeast China and our airport is expected to reach saturation point by 2017. While our airport contributes much to our affluence, I don't think we should build a third runway because it will harm our sustainability.
The construction will bring water, air and noise pollution through massive reclamation and harm nearby aquatic life, including precious Chinese white dolphins.
A third runway will mean the number of flights will double or triple, resulting in more deafeningly loud noise, especially for Tung Chung residents.
The huge cost means it is impossible to endlessly expand the airport to maintain our dominance in the region.
So to raise its competitiveness the Airport Authority should spare no effort to enhance its efficiency. It also should improve its accessibility by co-operating with other means of transport and even rival airports.
