God said to them, "Be faithful and multiply, and fill the earth and subdue it; and have dominion over every thing that moves upon the earth."
Well, we've done very well with the multiplying and filling the earth part. If that's what God meant about being faithful, then we have been. But, if God was more concerned with the dominion part, we may not have been.
If dominion means something like dominate, then we humans have been working on that. But, if dominion really means something more like having responsibility for the care of, then we need to improve our efforts.
