SpaceX's Starlink satellites have a lot of scientists worried about Earth's atmosphere
Briefly

The number of satellites in Earth's orbit has skyrocketed from about 1,000 in 2010 to more than 10,000 today, with an additional 58,000 expected by 2030.
About 100 scientists signed a letter in October urging the FCC to pause mega-constellations, stating, 'We should look before we leap;' the environmental harms are not fully understood.
Studies indicate that rocket launches emit pollutants that could deplete the protective ozone layer, raising concerns about the impact of thousands of satellites.
SpaceX's Starlink alone accounts for more than half of the active satellites, prompting worries among scientists regarding the environmental consequences of mega-constellations.
