A single Falcon 9 rideshare launch had 115 satellites in it, several of which were tugs that will deploy additional satellites. So, 126 sats deployed from that one launch. On the one hand, great, because rocket launches pollute a lot. On the other hand, holy crap that's a lot of satellites at once.
42 rocket bodies in orbit from all these launches (rocket bodies are often bus-sized or larger, so this is scary). 23 were promptly deorbited, 19 left for uncontrolled reentry later.
