"We have indeed been out in space, but some are under the illusion that we have been off Earth. In reality humans have never been off Earth. We have always been on a piece of Earth in space. We survive only as long as we can breathe the air of Earth, drink its waters, and be nourished by its foods. There is no indication that as humans we will ever live anywhere else in the universe. Place, too, is continuously being transformed but only within its own possibilities."

-- Thomas Berry
