You can survive 5-6 days without food. 2-3 days without water but without oxygen you would not even survive for a few minutes. And that's show how important it is for us and our earth to survive.
So, more oxygen means more air and better livable climate? Well we don't think so! This is Now You Know and in today's video we will tell you what will happen if the Oxygen present in earth's atmosphere doubles up.
Our atmosphere contains almost 21% oxygen and roughly 78% nitrogen. We inhale 23,000 thousand breaths every single day providing air to our brains and cells. Oxygen is essential for our survival and is the most important part of our atmosphere.
90% of our body energy comes from oxygen and the rest 10% from water and food.
As the oxygen doubles up, the insects would grow big in size. Insects breath through trachea and as more oxygen they breath they would grow much larger. Dragon flies would the size of a Bull and spider would be as big as an eagle.
With that happening human beings will have much more energy, and they would be much more alert. More oxygen in your body improves your circulation, humanity would less diseases.
The increase amount of energy would also increase the chance of serious long term health problem. When your body is exposed to high level of oxygen you are at a risk of damaging your lungs, not only that you will have poor eye sight and your cells will not be able to reproduce.
As the level of oxygen increases in your body it creates free radicles which can even damage your body and DNA. As the oxygen level rises you will be seeing more forest fire almost every day.
So, With some good and some bad you take slight relive that this is not going to happen anytime soon.
