The term Anthropocene was suggested by atmospheric chemist Paul Crutzen in 2002 as the name for the present geological epoch in which humanity has become a significant geological agent. It is often accompanied by the more controversial concept of planetary boundaries, within which a safe operating space for humanity can be defined (Rockström et al. 2009 Rockström, J., W. Steffen, K.
