Some geologists believe that humanity's effects on the planet are so significant and enduring that the Earth has entered a new epoch: the Anthropocene.
"Geologists wonder if they should add a new epoch to the geological time scale. They call it the Anthropocene – the epoch when, for the first time in Earth's history, humans have become a predominant geophysical force. Naming such a new epoch would also recognize that humans now share responsibility with natural forces for the state of our planet's ecological environment."
"Geologists have been using the term informally for at least half a decade. Now members of the Stratigraphy Commission of the Geological Society of London have laid out the case for giving the term official scientific status."
"Presenting that case in the February issue of GSA Today magazine, the team notes that "since the start of the industrial revolution, Earth has endured changes sufficient to leave a global stratigraphic signature." It is different from anything found in the entire geological record up to that point. That means the team expects future geologists examining this record will recognize a distinct break with the Holocene ("recent whole") epoch that covers the past 10,000 years."
"Soil scientist Daniel Richter at Duke University in Durham, N.C., would agree. In an announcement of his work last month, he explained that human-induced changes to the world's soils are enough in themselves to justify saying we have entered the 'Anthropocene (or man-made) age.' He notes, 'With more than half of all soils on Earth now being cultivated for food crops, grazed, or logged for wood, how to sustain Earth's soils is becoming a major scientific and policy issue.'"
