中国古代先哲老子生活的春秋时代,遥远的星系中有颗行星叫天球。在那里生活的人类已步入了科技、文明高度发展的后工业时代。然而,天球的生态环境已经恶化,臭氧层几乎消失怠尽,地表多数已被沙漠覆盖,能源枯竭、食物短缺,至使天球人类不得不常年穴居地下。天球只剩下一个靠高科技手段人工制造大气臭氧层,并集中使用能源维持自然生存环境的孤岛——自然乐园。 Ancient Chinese philosopher Lao Zi’s life in the Spring and Autumn era, distant galaxies have a planet called celestial sphere. The mankind living there has stepped into a post-industrial era of highly developed science and technology and civilization. However, the ecological environment of celestial sphere has deteriorated, the ozone layer has almost disappeared, the surface has been covered by deserts, the energy has been depleted and the food has been in short supply, so that the celestial globe has to inhabit the perennial. The celestial sphere has only one isolated island - a nature paradise that uses artificial high-tech means to create an atmospheric ozone layer and uses energy to maintain its natural environment.
