《人类之后的地球》
设想在遥远的未来，外星人造访地球。他们会不会发现什么线索，证明这里曾经有过智慧生物的繁荣？我们的城市、大坝、工厂会不会留下什么遗迹，能在1亿年后被探测出来？这是一项简单而有趣的思考实验，在某种程度上正是简•扎拉斯维奇(Jan Zalasiewicz)这本精巧的地质学图书所探究的问题。

“The Earth After Us”
Imagine alien visitors arriving on Earth in the remote future. What evidence may they find to tell them that intelligent beings once thrived here? What fragments of our cities, dams and factories may be detectable in, say, 100 million years’ time? It is a simple but intriguing thought experiment that is explored, to some effect, in this neat little geological entertainment by Jan Zalasiewicz.
