除經濟因素外，摩天大樓過于密集造成的光污染、氣旋等問題都引發爭議，如果3幢摩天大樓比肩而立，附近馬路上的行人走過，會不會因為形成風洞而發生危險？此外，2001年的“9.11”事件也讓人擔心，一旦浦東崛起兩座甚至3座摩天大樓，會不會成為恐怖分子的目標？一旦發生飛機撞擊以及火災等意外，在大樓上的人是否能夠安全撤離？

Skyscrapers are also challenged， besides people's consideration of the financial factors， for such problem as the possible light pollution and cyclone resulting from the high density of high building at the same place. Will the wind tunnel formed there endanger the passers-by when 3 skyscrapers are built side by side？ In addition， people are also worrying about the potential attacks from the terrorists to the 2 to 3 new skyscrapers in Pudong after the September 11th terrorist attack to the USA. Will the people in the buildings will withdraw in time in event of such accidents as air collision or fire.
