Beware the Dangers of Oxygen

There’s a caustic substance common to our environment whose very presence turns iron into brittle rust, dramatically increases the risk of fire and explosion, and sometimes destroys the cells of the very organisms that depend on it for survival. This substance that makes up 21% of our atmosphere is Diatomic oxygen (O₂), more widely know as just oxygen. Of course, oxygen has its good points. Besides being necessary for respiration and the reliable combustion engine, it can be liquefied and used as rocket fuel. Oxygen is also widely used in the world of medicine as a means to imbue the body with a greater amount of the needed gas. But recent studies indicate that administering oxygen might be doing less good than hoped–and in fact be causing harm. No one is immune to the dangers of oxygen, but the people who might most suffer the ill effects are infants newly introduced to breathing, and those who are clinically dead.
