Humanity has etched its way into Earth’s geology, atmosphere and biology with such strength and permanence, a special team of scientists figures we have shifted into a new geologic epoch, one of our own creation. It’s called the Anthropocene.
A geological task force is recommending to mark this new epoch’s start in the small but deep, pristine Crawford Lake outside Toronto, Canada with a ‘golden spike’. The start of the human epoch is sometime around 1950 to 1954. The specific date will be determined soon, probably by levels of plutonium in new measurements from the bottom of the special lake site.
“It’s quite clear that the scale of change has intensified unbelievably and that has to be human impact,” said University of Leicester geologist Colin Waters, who chaired the Anthropocene Working Group that is making the recommendations. “It’s no longer just influencing Earth’s sphere, it’s actually controlling.”
