A real thought provoking video...Qatar really need to think very seriously about the issues of scrap, garbage disposals, road accidents, labour safety. Air pollution, i dont think can be controlled due to many of the industries and vehicles and difficulties in growth of the trees due to heat. And yes as Erasmus said, not all the public drinking sources are as clean and gives out the pure water. Some of them are as shown in the videos while some are safer to drink . I have experienced it.
