For some people, the fact that the world is becoming a neighbourhood is a reason for hope; for others, a cause for concern. For all, it provides an impetus for common action. The more people become aware of the growing interdependence of human society, the more readily will they overcome destructive notions of 'otherness' and 'separateness' and find ways to work together. There are no shelters to insulate anyone from disease, poverty, nuclear holocaust or environmental collapse. Such problems are not so many separate crises as elements of a global neighbourhood crisis. All destinies are intertwined. Our response must have a unifying dimension.
