FOOTPRINTS: In Search of Future Fossils

A profound meditation on climate change and the Anthropocene and an urgent search for the fossil - industrial, chemical, geological - that humans are leaving behind. Farrier explores what traces we will leave in the very deep future, from long-lived materials like plastic and nuclear waste, to the 50 million kilometres of roads spanning the planet. In modern times we have created numerous objects and landscapes with a potential to endure through deep time. Our carbon could linger on the atmosphere for 100,000 years, and the remains of our cities will still exist millions of years from now as a layer in the rock. These future fossils have the potential to tell remarkable stories about how we lived in the 21st century. Through literature, art and science, the book invites us to think about how we will be remembered by our distant descendants. Travelling from the Baltic Sea to the Great Barrier Reef, and from an ice core laboratory in Tasmania to Shanghai, one of the world's biggest cities, fossilised remains will speak of life rather than death. Even the contents of our sandwiches will tell a story. 60 billion chickens are killed for human consumption each year and in the future, fossilised chicken bones will be present on every continent within a layer in the geological strata, as a testimony to the intrusion of human appetites in the geological record. 'In my search for future fossils, I look to the air, the oceans, and the rock, from a bubble of ice drawn from the heart of Antarctica to a tomb for radioactive waste deep beneath the Finnish bedrock.' 307pp.
