It is scientifical proven that we don't need air to breath, in fact, we are space aliens that came to earth. The former population on this planet was annihilated by our superior technology, but the government turned as into sheeps. We have become independant on oxygen, so we would develope a weakness that the illuminati can take advantage off.
Stop breathing, go back to your roots.
Edit: The scientists were murdered by agents. The proof never went public, but I have connections so I know.
