I have heard many people now try to push the agenda of cleaning up space, which is not only a very challenging and expensive venture, but doesn't seem so important. I know there is some crowding up there, but in all honesty, is there much to worry about? The amount of space at that distance from the planet is immense, and it will clear out as old satellites slowly fall in decaying orbits, and they will burn up harmlessly in our atmosphere, making room for more new satellites.
Is this really so much of a concern? In an emergency, the Americans could just shoot them down with there nifty anti-satellite devices. Do we really have anything to worry about?
