Don't be sad.... it will be back up again in the morning. But how sure are we that the sun will rise up again to shine our world? As sure that there will be a Sunday in a week? It will peek pass the moons and planets during eclipses and continue to provide the Earth with its ray of hope. We never question the Sun's loyalty in providing the Mother Earth that much needed energy. It is us who stay on this planet who continue to plunder and deplete Mother Earth's resources and polluting the various layers of biospheres. One day when its too late we will discover that we only have One Earth which provides us with this One Life we have to Live, to make tomorrow a better place for our future generation. Love our Earth, our One Earth! Pssst...lets grab some beer now and wait for Sunrise :)
anyway, happy earth day to you!
