I study orbital debris for a living - I'd like to assure you that you don't need to feel too worried about that. Orbital debris is generally consolidated in very thin altitude bands. Rockets on an escape trajectory spend very little time in these shells, only in passing. Compare that to satellites with lifetimes of 15 years.

Niel's statement is analog to saying "The LHC could create a black hole that kills us all". Yeah... I guess on some theoretical level it's possible... but it's extremely unlikely. Same concept applies here. I'm quite disappointed in him saying "There's a very good chance", because that is far from true.

Here is the clip from when they start speaking about the space junk. My memory did not quite remember the exact words Neil used so what I wrote was not entirely accurate. Apologies.

He wouldn't get invited to speak if he didn't make pompous grand statements though.
