If the use of some industrial process is proven to have harmful effects on the environment, I can see regulating or banning it's use in non-defense or non-space related applications, but how much actual damage to the environment has been prevented by NASA's conformance? There are a handful of shuttles - I don't think the ozone layer is going to go away because they are safely heat-proofed. Pure lunacy, and lives may have been lost as a result.
I lived in Florida in the 80's and some idiot leftist Science professor was quoted as saying the Shuttle would destroy the Ozone layer. She said by the 100th launch the ozone layer would be gone. Since I worked on the Shuttle program, I had an interest in keeping such pronouncements. I filed the article away. Some day I will have to dig it up and post an image of it. She was a lunatic.
