What kind of fossils will we leave, as relics into the far future? A blizzard of new objects has suddenly appeared on Earth: plastic bottles, ballpoint pens, concrete flyways, outsize chicken bones, aluminium cans, teabags, mobile phones, T-shirts. They're produced for our comfort and pleasure--then quickly discarded. The number of our constructions has exploded, to outweigh the whole living world. This new-made treasure chest underpins our lives. But it is also giving a completely new style of fossilization to our planet, as hyper-diverse and hyper-rapidly-evolving technofossils spin out of our industrialized economy. Designed to resist sun, wind, rain, corrosion and decay, and buried in soils, seafloor muds and the gigantic middens of our landfill sites, many will remain, petrified, as future geology.
What will these technofossils look like, in future rock? How long will they last and how will they change, as they lie underground for decades, then millennia, then millions of years? Discarded describes how they transform as they are attacked by bacteria, baked by the Earth's inner heat, squashed by overlying rock, permeated by subterranean fluids, crumpled by mountain-building movements--and what will be left of them. These new fossils also have meaning for our lives today. For we live on a world increasingly buried under our growing waste. As our discarded artefacts begin to change into fossils, they may be swallowed by birds, entangle fish, alter microbial communities and release toxins. Even deeply buried in rock, technofossils may break down into new-formed oil and gas, change the composition of groundwater, and attract new mineral growths. They will have a lasting impact.
