One of the benefits we noted when humanity first was able observe the earth from above our atmosphere, from outer space, is that it enabled us to gain a new perspective on how very special our planet is. Viewed from a distance, it is obvious that we are all living in one global environment. And from a distance, this environment doesn’t look as vast as it does from our vantage point on earth.
The land looks more precious, the seas less like unlimited places to discharge our wastes, and the atmosphere, less like a place to emit air pollution at night so no one sees it, to the fragile envelope which, more than anything, makes earth the special place it is.
Indeed, it is the atmosphere that permits life as we know it to flourish on earth. And we owe most of this new knowledge to the National Aeronautics and Space Administration!
