The sun comes to rest so briefly on the horizon before it sinks from sight and another day on this beautiful earth comes to an end. All that has ever been continues to be what it always was. All that has not yet been awaits its birth and growth. There is no start or finish to the boundless range of all that is possible, all that could be. The earth will go on; it does not care about us. Mother Nature does not care about us. It is up to us to care.
