I am one of those benefiting from the wealth of street painting and cleaning campaigns which have made our neighbourhood pretty and all. Yet I have an alternative suggestion I would like you all to ponder. Rather than investing money, time and effort to painting sidewalks, lets promote a Plant A Tree day in the streets of Egypt. It can be on the sidewalk right in front of your own house, or in the island in the middle of the street. You can walk up to the closest patch of greenery and plant a tree or some flowers. Think of how pretty Egypt would be then. It would also hopefully then have slightly more oxygen.
