The concept of novel ecosystems (CNE) has been proposed as a way to recognize the extent and value of ecosystems that have been irreversibly transformed by human activity. Although the CNE has recently been subject to critique, existing critiques do not appear to seriously engage with the extent of anthropogenic change to the world’s ecosystems. Here, I seek to provide a deeper, philosophical and constructive critique, specifically arguing that the usefulness of the CNE is limited in the following three ways: (1) it is too static, (2) it is too vague, and (3) it is too dualistic. Although the CNE provides some conceptual advance (“new wine”), some of its conceptualization and packaging weakly support this advance (“old wineskins”), so I consider some ways to further develop it, in part to encourage more widespread recognition and appreciation of novel ecosystems.
