A recent film, "The God Must Be Crazy", described the social change that can result in a society from the introduction of a single item from the outside world. While a pilot was flying in a light plane over a remote desert in south Africa, he finished the soda he was drinking and threw the bottle out of the window. It fell to the ground in an area where an African tribe lived.  The people there had almost no possessions or sense of private property. No one in this small remote society had seen a soda bottle before. And, because it came from the sky, they believed that it must be a unique gift from the gods. When the bottle was first found, it was something new and people of all ages enjoyed admiring it, playing with it and thinking about its purpose. It was not very long, however, before arguments and conflicts arose among group members about who would possess the bottle and for what purpose. The harmony of this peaceful society was disturbed by the introduction of a new item of technology. And, as it was told in the film, ties of affection were broken, and people’s trust in each other disappeared.
