    There are a lot more than 40 tons of manmade satellites and small debris from 
    manmade satellites in low Earth orbit and it stays within the volume of space 
    that ISS travels through while the 40 tones of meteor debris zips through that 
    space at 15-30 kilometers per seconds on its way to the atmosphere.  Most 
    satellite impacts are from that man-made debris.  Anyone got any LDEF research 
    summaries handy - one of it's goals was to sample its exposure to the various 
    space debris, both natural and manmade.
