The term “Ecozoic era” was coined by Thomas Berry in conversation with Brian Swimme for their book The Universe Story in order to describe the geologic era that Earth is entering – when humans live in a mutually enhancing relationship with Earth and the Earth community.
Earth is entering a new geologic era because the previous one, the Cenozoic era (spanning the last ~65 million years), has been terminated by the western-style industrialized human community in the late 19th, 20th, and early 21st century.
