林奇回忆在20世纪50年代，那时候，新闻媒体中充斥着核战争的威胁，人们开始修筑战时掩护所，储存食物和水。

Lynch recalls the time during the 1950s when the threat of nuclear war was so prevalent in the news that people began building fallout shelters and storing food and water.

在20世纪80年代，那些“末日先知”们找到了另一个主题：核冬天的威胁迫在眉睫。苏联与美国之间的核战争的结局，会是地球生命灭绝的潜在结局。

In the 1980s, the prophets of doom found another theme: the imminent danger of nuclear winter, the potential end of life on Earth resulting from a Soviet-American nuclear war.
