  • Question

    What would happen if trees one day stopped giving of oxygen, why? How would we know if trees stopped giving off oxygen?

    Answer

    Megastonefilms, producing oxygen is a fundamental part of tree's (and other plant's) physiology. They cannot choose not to for it is part of their life cycle. For this not to happen would mean the plant would be dead (in which case we would know). Certainly, if they did stop producing oxygen, after enough time the oxygen content of the air we breathe would begin to decline.
