Earth has oxygen. But I don't know why you have to call it "free oxygen". It's not really "for free". People have to plant trees in order to receive oxygen. They are the ones that are supposed to be responsible for their lives. Earth supports the humans by giving them a place to plant, that's why it is the only "living planet".
