The ethic underlying "Earth Care" could perhaps be expressed more clearly as "Biosphere Care," thus emphasizing our commitment to the health of the tremendously complex, dynamic, interconnected living systems upon which we are utterly dependent, while remaining open to the future possibility of finding/establishing biospheres on other planets. Of course, right now we have only the earth, so let's take care not to wreck it.
