Fine powder of metals strewn over a few km², there’s more coming from outer space via micrometeorites and dust. And that bit CO² in the Stratosphere…

Yeah but you also have to manufacture and send up the satellites into LEO.

Also counterintuitively, you need some fuel to deorbit, which adds payload weight at launch and requires more fuel in the first place.
For example, getting a unit of rocket fuel to the Moon requires about ten times as much at launch.

I don’t think they need much fuel in this case unless they want to be absolutely sure that they deorbit in the right place. The satellites are so small that might not even be needed.

Yes, it takes little fuel to destabilize one’s orbit and eventually enter the atmosphere to burn up. It’s more difficult if you need to make sure that the craft doesn’t take others down during the procedure.

Starlink’s only have fuel because of the initial lower orbit, as far as i know. Wasn’t that to test them, for radiation and so on?
