I saw on T.V. the other night that some people are planning to go in to space and salvage all the “space junk” that is orbiting around the earth and recycle it. They say there are massive amounts of junk flying around earth from discarded shuttle parts to abandoned satellites. They are also talking about dismantling the international space station. This leads me to wonder, we have trashed the earth, are we destined to trash every place we go. If we establish a base on the moon will they have to plan for a land fill there too?
