That is satellite reentry, nothing to do with rocket launches. Building satellites out of something other than aluminum solves the issue, but even with mega consolations the effect is not super significant.
What do you think all these launches are putting up there? Starlink mega constellation satellites maybe?
Getting a rocket like this would probably allow for satellite to be built with materials other than aluminum because the cost goes down per launch since the rocket is reusable and the payload is so high the cargo doesn't have to be built as light as possible.
In the process, we probably permanently damage the atmosphere.
Nope, this was a test launch.

How does that relate to what I said? Starship has not launched any payloads yet. Your original comment said this rocket should be banned because it depletes ozone. It doesn't. You should say we should outlaw SRBs, soot trails, and aluminum satellite reentry, not ban starship or rockets in general.
Why would I say to only outlaw those specific items? We need to stop launching all this commercial garbage into space without knowing all of the harm it causes. I don't think we should wait until it's too late to see how harmful it has become.
Relax with the commercial launches. Its hurting all of us.
Because we have reason to believe those things might be harmful. We do need much more research to see how harmful they are to ozone, since the one paper's conclusion was that tens of thousands of satellites re-entering each year may have a percent or two effect on ozone. But I don't see why we would ban rockets that we have no reason to believe hurt ozone.
It's definitely not 1 or 2 percent. You are downplaying the issue by a ridiculous margin.
How many percent is it?
Like I said previously, who really knows until the studies have been done. There hasn't been time to study the effects. Should we wait until there are tens of thousands of satellites in the sky? Or hold off for now, have some patience, and wait for our scientists to catch the data? Whats the big hurry?
I don't have access to dig though it right now, but I thought the NASA paper showed couple percent increase in ozone deterioration.
