How strange and wonderful is our home, our earth, with its swirling vaporous atmosphere, its flowing and frozen liquids, its trembling plants, its creeping, crawling, climbing creatures… To see our world as a space traveler might see it… how utterly rich and wild it would seem… Yet some among us have the nerve… to whine about the limitations of our earthbound fate and yearn for some more perfect world beyond the sky. We are none of us good enough for the sweet earth we have, and yet we dream of heaven. ~ Edward Abbey (Photo by Will Davidson)
