some folks at work were talking about all these rocket explosions and whatnot are actually causing another hole in the o-zone layer again… not sure if true
It’s not true. Steel is a non-combustible metal and these rockets are fueled with Methalox. Methane is not an ozone depleting chemical and neither are its combustion products. Physical effects and chemical by-products from satellite re-entry are linked to ozone depletion, so Starlink is the actual thing that SpaceX is doing to fuck it up, as /u/boiledfrog mentioned.
The water vapor added to the air from methane combustion can impact polar cloud formation that might have some impact on ozone layer replenishment, but there’s a lot of complexity there and seemingly even things like groundwater well usage may have impacts on this.

Don’t know about the rocket but there are possible effects from the alluminum that gets released when they burn up satellites in the atmosphere.

That’s outside my scope of understanding so idk
Did they also say that each launch tilts the earth a little more on its axis?
lol
