It is tantamount to child abuse to expect school children to travel on non airconditioned buses in 50 oC heat. If parents put their children in cars at 50 oC I believe it would be called child abuse by the authorities and they would probably have to face the courts. Temperatures of 50 oC, (122 degrees Fahrenheit) would not be tolerated in city buses and trams and wont be tolerated by country people either particularly for our children.
