During the 1980s, the world was confronted with a new and fightening environmental concern - ozone depletion. The term "ozone hole" is now a common phrase, but just what does it refer to and why should we be concerned about it? 40亿年前,臭氧层形成之前,地球一片荒芜。臭氧层的形成,有效地阻止了紫外线辐射,成为地球上所有生物不可或缺的防护网。而现在科学家骇然发现,在南极寒冷的高空上,一种看不见的化学反应正在这个防护网上刻出一个漏洞,这个漏洞,拉响了全球的警报,成为20世纪最让人类烦扰的奥秘之一。





臭氧漏洞为什么只在南极存在?它将对地球产生怎样的后果?它仅仅是个自然现象,还是人为影响造成的呢?……现在,就让我们跟随世界顶尖科学家们的脚步,前往冰天雪地的南极一探究竟……
