The latter, dubbed the sixth mass extinction in Earth history, is largely attributed to increased human population and activity, and may have started already during the preceding Pleistocene epoch with the demise of the Pleistocene megafauna.
The Holocene extinction, otherwise referred to as the sixth mass extinction or Anthropocene extinction, [109] [110] is an ongoing extinction event of species during the present Holocene epoch (with the more recent time sometimes called Anthropocene) as a result of human activity.
