In a recent paper titled The New World of the Anthropocene, which appeared in the journal Environmental Science and Technology, a group of geologists listed more than a half dozen human-driven processes that are likely to leave a lasting mark on the planet — lasting here understood to mean likely to leave traces that will last tens of millions of years. These include: habitat destruction and the introduction of invasive species, which are causing widespread extinctions; ocean acidification, which is changing the chemical makeup of the seas; and urbanization, which is vastly increasing rates of sedimentation and erosion.

Human activity, the group wrote, is altering the planet “on a scale comparable with some of the major events of the ancient past. Some of these changes are now seen as permanent, even on a geological time-scale.”
