Starlink made the satellite with high emission rays which showed strong light from space in their first test after which NASA sent an official letter to SpaceX which they have decided to use lower emission materials for the satellites which means the satellites that went up for testing has started adding up to the debris if they are not being used again.
I suppose that the space debris can be solved by making biodegradable satellites and with an AI that makes them return to Earth or allow self-repair, request help from one or more satellites in the network; I don't know, everything is possible.
This is a opinion. Thanks for reading my post.
