Listen: I know it seems counterintuitive to someone like you, someone who’s just crawled up out of the hole and into space, but oxygen is not free. You have to pay for it, just like food or water. Air has to be lifted in ships or made in the belt and tossed here by the catapult. Believe me, if we had room to plant trees, or soil to plant them in, we would. But even then, the soil would have to be made or lifted, and so would the seeds. Either way, it costs money to breathe. So pay up.
