Chistophe Bonneuil and Jean-Baptiste Fressoz “Preamble What has happened on Earth for a quarter of the millennium? Antropocene. Antropo-what? Antropocene; we are already there, then we need to breathe this barbaric word as much as what the name comes from. It is our time, our status. This geological era has reversed our history for more than two centuries. Antropocene is the sign of our power, but also of our impotence. It is a land whose atmosphere is disturbed by a trillion four hundred billion tonnes of CO2 that we have thrown off when we burn coal and oil. It is an impoverished and artificial living tissue, impregnated by a large number of new synthetic chemical molecules that change to our offspring. It is a warmer and heavier world of risks and disasters, with reduced glacial cover, seas higher, unarranged climates.’
