c. 10,000 BC marks the agreed date of the beginning of the Agricultural Revolution. In a seminar room at Haus der Kulturen der Welt, Berlin, during Anthropocene Campus 2014, a group debated whether to date the beginning of the Anthropocene to the Agricultural Revolution, the Industrial Revolution, or the Nuclear Age, as well as the concept of the Technosphere, whereby technology has become a transformative force alongside the bio-, the hydro-, and the atmosphere, and its impact on the co-evolution of society, nature, and mankind.
