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. Jim.
