Oxygen is one of the most important gases on our planet. It is composed of 2 oxygen molecules, and without it, we would not be able to breathe and live. Oxygen powers most of our body, as red blood cells carry it around the body to keep our organs running. Without oxygen, we would be dead in a few minutes.
