So are many various gases and minerals on earth, and despite all the devastating war and accidents we've had we've hardly scraped the planet's surface.
Comparing so called "volatile" materials on earth to tibanna on a gas giant world is idiotic, Ralen. I explained very carefully just how it occured, and no one protested it.
Therefore, it has happened. The time for you to protest is long over. It's up to you to deal with the damage done.
I'm not denying lasting damage, but the destruction of an atmosphere isn't exactly easily attained.
No, you're right, it isn't. But then, I detonated what amounts to a city-sized bomb in planet filled with gas that essentially combusts when energy touches it. If I'd shot some lasers into the atmosphere and declared it over and done with, now, that'd be something.
Besides which, it's not as if I completely roasted the planet's entire atmosphere. The tibanna on Bespin is contained in relatively small pockets, which were penetrated by the massive amount of heat and light energy released by the detonation of Cloud City, releasing themselves more heat and light as they too exploded. Most of these pockets are now obliterated.
Either way, I would question how you could so quickly rebuild such an absolutely mammoth station and then somehow convinced millions of civilians to move in overnight. The problem isn't that you've found a way to harvest tibanna again -- there would be some left -- or that you've replaced the city. It's that you've done both to such an enormous degree and essentially restored everything to absolute normal by snapping your fingers.
