The Anthropocene would begin directly after the termination of the Holocene Epoch, but much debate and controversy currently relates to when exactly that date should be – should it begin thousands of years ago, perhaps relating to when our ancestors began widespread agricultural clearances? Should it begin with the Industrial Revolution or during the Second World War? In fact, some scientists even consider that it should begin as recently as the 1960s. Interestingly, the term ‘Anthropocene’ only came into being very recently, in 2000, when a Dutch Nobel Prize-winning chemist named Paul Crutzen made an off-the cuff comment at a press conference and, just a few years later, the International Commission on Stratigraphy (ICS) Working Group on the Anthropocene was formed. Paul Crutzen rightly drew attention to mankind’s influence on the planet and the need to guide society through man’s impact (mostly deleterious).

However academically satisfying it is to promote a concept, it is quite a different … Read More
