Here is a graphic showing various planned LEO constellations.

Launched satellites: 12,529
Planned: 2,257,509 (some fraction will get deployed)

Most satellites need to be replenished every ~5 years, as they descend and burn up in the atmosphere, releasing ozone-destroying metals.

Astronomers have been screaming about their effects on astronomy, both ground based and space based and the potential for Kessler syndrome.
