Kessler can be mitigated by a civilization capable of launching enough mass. Pretty much all you need is to cancel out the angular momentum of existing debris.

Kessler can be mitigated by a civilization capable of launching enough mass. Pretty much all you need is to cancel out the angular momentum of existing debris. It would just cost a lot. However right now with our regulatory environment Kessler is not likely. Starlink is very low orbit and they decay without power in a matter of months if not weeks. Also every satellite launched is required to have a deorbit plan or a plan to move it to a parking orbit if it's a geostationary satellite.
