All these metals that we're spraying into the atmosphere on reentry burn are even worse than PFAS in the hydrosphere, in that unlike PFAS (which after 1000's of years do eventually decay) they are pretty much permanent, never cycled out of the atmosphere.
Space junk burn may prove to become our most indelible mark on this planet.

Don't worry, it won't hurt us.
