A gathering was organised to show displeasure against the government's Population White Paper. The upper estimate of 6.9 million people by 2030 angers many people who are already complaining of overcrowding. In June 2012, the population was 5.31 million [Population White Paper].
"Protest against the 6.9 million population target by 2030. We welcome foreigners to join us for the event as we are discussing mainly on the flawed policies of the government."
Showing displeasure by gathering at a designated public place peacefully is better than rioting and throwing expletives online. Attending such event is also a way to display disagreement. This is better than bottling such emotions and harbouring negative emotions. In other words, it is a stress-relieving event.
