 OUR PLANET EARTH
 OUR LIVABLE PLANET The images of earth from space are startlingly beautiful. Perhaps the most famous is the original "Blue Marble” image taken by the crew of Apollo 17 in 1972 (as shown above). This image of our blue planet, unique among planets in its abundant water, made the fragility of life on earth very real to many people. Certainly without water, life on earth as we know it would not exist. But, what might be less well known is that it is the earth’s atmosphere that makes abundant water on earth possible and enables life to flourish. The thin blanket of gases, tiny water droplets and dust particles making up the earth’s atmosphere provides us with oxygen to breathe, precipitation to nourish our ecosystems and a stratospheric ozone shield that protects living things from harmful ultraviolet radiation from the sun. Hi, my name is Lisa, and welcome to my web site dedicated to preserving and protecting this precious planet of ours. |
