The impact of our species on the conditions and fundamental processes on Earth is unmistakable. From carbon emissions to the cities that dominate skylines to the plastics that swirl around in our seas, the evidence of our existence can be found anywhere. And now, a group of geologists considers our impact so drastic that a new epoch – the Anthropocene – should be declared. Whilst this change has gained support in much of the scientific community, others say that the Anthropocene is more about sensationalism or pop culture than science, as clear evidence for a new geological time is lacking. So whilst much of the scientific community, the general public and the media have already embraced the Anthropocene, the search for hard evidence for the start of a human-dominated age continues.
