The Earth after us

the long version

"Jan Zalasiewicz shows how scientists put together clues from the rocks to understand the past, its landscapes and climate, and the nature of the creatures that inhabited it. A thin layer of silt here, a trace formed by a crawling worm there - the clues are often subtle and difficult to read. But by such clues would future geologists - whether hyper-evolved rat or alien visitor - work out our story. Zalasiewicz explores which of our structures are likely to leave traces, and what future explorers might make of us and the impact we made on our environment."--Jacket.
