On the one hand yes. But, and this is a big but, typically when ships are sunk by the government, a lot of environmental impact studies and decontamination processes are preformed. The goal is usually to create artificial reefs, which is pretty useful because of how much damage we’ve done to the natural habitats.
Does it balance out, or make up for it? I don’t know, I’m not smart enough. But I do know the artificial reef projects are greatly appreciated and highly desired by local governments.
The rear spoiler thing on my hatchback trunk is starting to peel and I thought it would be easy to remove and repaint myself. But I was surprised to learn it’s just glued on. But it’s just a trim piece of plastic with a brake light and a fluid nozzle in it. Not a body panel per se.
