It's a natural element, and one of the basic building blocks of life on Earth.
And no, you can't "stop" carbon emissions without exterminating every animal on Earth.
Redefining clean, natural air as "pollution" is exactly what Orwell warned us about:
“Don't you see that the whole aim of Newspeak is to narrow the range of thought? In the end we shall make thought-crime literally impossible, because there will be no words in which to express it. Every concept that can ever be needed will be expressed by eactly one word, with its meaning rigidly defined and all its subsidiary meanings rubbed out and forgotten. . . . The process will still be continuing long after you and I are dead. Every year fewer and fewer words, and the range of consciousness always a little smaller. Even now, of course, there's no reason or excuse for commiting thought-crime. It's merely a question of self-discipline, reality-control. But in the end there won't be any need even for that. . . . Has it ever occcured to you, Winston, that by the year 2050, at the very latest, not a single human being will be alive who could understand such a conversation as we are having now?”
― George Orwell, 1984
