What is really happening when Satellites “burn up during re-entry”? Is there any debris left? Is it toxic? Can anyone get hurt?

Question

Apparently instead of once in a while at a predictable time/path, now satellites are going to be dropping from the sky all the time?

Has anyone verified that is safe for the planet and people below?

Almost seems like someone throwing toxic sludge into the ocean and saying “well the ocean is huge and it’s only a little toxic so no big deal” until it’s done thousands of times over and over and it’s only trivial to them because they can’t see the final damage?

Nothing is inherently ‘toxic’ about satellites. Most things that enter the atmosphere uncontrolled do not make it to the surface in one piece.
