Description
Anthropocene describes the time during which humans have had a substantial impact on our planet. For the past several decades, several scientific and social science communities have been wrestling with this concept and its importance. We have reached a period in Earth’s history, and thus human history, where humankind continues to profoundly influence Earth processes on a global scale. The geoscience community continues to debate whether the Anthropocene should be an official time unit in the ever-improving geologic time scale for Earth.
