Hong Kong is a city which highly urbanized, buildings is surrounded in the city. In this environment, we pursue "Green" naturely. In my opinion, greening the city should reconstructed relationship between man and nature. But people love to self-deception, The things go “Green: just some natural scenery image on the wall of construction sites to hidden the damage to the environment from the site or the cold concrete: a fake “Green” cover up the truth about the development of damage. After development, only concrete building plant but not the real tree. In my opinion, all this are pseudo-green.
