Hey mate ❤
Here's ur answer
Your typical breath of fresh air contains about 21 percent oxygen. The extreme majority of the remainder is nitrogen, while about one percent is CO2, argon, carbon, water vapor, methane, etc. The air contents are very meticulous, because any more or less of those elements in the air could cause certain species to die out.
If a human were to breathe air with a much higher oxygen concentration, the blood wouldn’t be able to carry it away leaving an excess of oxygen in the lungs. The extra O2 binds to the proteins on the surface tissue, slowing down the central nervous systems. In some cases it also attaches to the retinas,
causing cataracts and other complications. However, this only occurs when the concentration is above 50 percent (decompression divers and firefighters usually have their tanks filled with nitrox, with oxygen concentrations between 22 and 40 percent).
