The term “Anthropocene” was first used 20 years ago to describe a new epoch of geological time, coinciding with the start of the Industrial Revolution around 1750. It indicates a transition out of the Holocene into a new age – the age of human impact. This term has incited great debate amongst the scientific community as, in order for a new new geologic epoch to be accepted, we need to demonstrate our impact on the rock strata around and beneath us. This was achieved in 2019.
