The Earth’s atmosphere contains around 21% oxygen along with 78% Nitrogen and 1% other gases such as carbon dioxide, neon, and hydrogen. Although oxygen is not as abundant in our atmosphere as Nitrogen, it is the most important for life. We humans, along with many other creatures, need oxygen in the air we breathe to stay alive. Without oxygen, we would not be able to do anything since our bodies need oxygen to obtain energy to fuel all our living processes. 90% of our energy comes from oxygen with the rest coming from food and water. So, without oxygen, we would not be able to survive even for a few minutes.
Now, this sounds like we could all use some more oxygen in the air we breathe. So, what if we cranked up the oxygen levels to 42% in the atmosphere? Surely this would only be good news for us all. Let us explore what would happen if we doubled the amount of oxygen in the Earth’s atmosphere!
