Excellent new report by the US Public Interest Research Group (PIRG): WasteX: Environmental harms of satellite internet mega-constellations https://pirg.org/edfund/resources/wastex-environmental-harms-of-satellite-internet-mega-constellations/
The report has great info on why 10s of thousands of throwaway satellites are terrible, and 2 powerful recommendations:
1. Pause launches until environmental reviews are done
2. Stop the categorical exclusion of satellites from environmental review
