Those entering the atmosphere make only one pass. Those in the Leonid,

With a little thought, you can probably figure out why man-made
orbital debris that spends months to centuries orbiting the earth
every 85-300 minutes, nearly all of it (surprise!) at distances and
inclinations quite like those of satellites and spacecraft, poses
risks that are greater by many orders of magnitude...

And why measures to prevent creation of new man-made debris are a lot
more practical than vacuum-cleaning the solar system....

And therefore, why responding to "man-made debris is dangerous" with
"yebbut there's natural debris too" might sound a little beside the
point.

Either by natural or artificial flack, we're somewhat screwed as far
as safe space travel is considered. Parking your butt on the moon is
actually a whole lot worse off than LEO, however the Selene/moon L1
might be relatively clean, except for being hotter than hell and gamma
radiated.
