If we deny our awesome challenge; turn our backs on the living universe, and forsake our cosmic destiny, we will commit a crime of unutterable magnitude. Mankind alone has the power to carry out this fundamental change in the universe. Our failure would lead to consequences unthinkable. This is perhaps the first and only chance the universe will ever have to awaken from its long night and live. We are the caretakers of this delicate spark of Life. To let it flicker and die through ignorance, neglect, or lack of imagination is a horror too great to contemplate.
