It's interesting that inevitably we will reach a `critical-mass` of this debris and a chain reaction will result. The fact that paint-chips travel at sufficient velocity to cause damage, I somehow doubt that even the most wild guesses as to the actual amount of debris is accurate. It must be several orders of magnitude too low. A lot of theories have been proposed to de-orbit these hazards, personally I think our only hope is MegaMaid.
