Introduction
摘要
Planet Earth has many worlds. These include worlds of culture, economic livelihood, ethnic and racial diversity, social well-being and environmental settings, but also political conflict, media reporting, migration, health care and healing. These and many other worlds exist side-by-side as well as short and long distances away. These differences can be explored, interpreted and even mapped in familiar/traditional ways or in novel ways using electronic media. These worlds for individuals, groups and countries may be visible and invisible in daily life as well as in contemplating and planning for present and future personal and global settings.
