What Would Happen If Oxygen Level Doubled In Atmosphere of Earth!

Can you imagine what would happen if oxygen levels doubled in the atmosphere of Earth? We know that our atmosphere is filled with nitrogen (78% oxygen (20% and smoke. There is around 21% oxygen in our environment, but you don't know that around 300 million years ago, our environment had 30% oxygen, and at that time, the trees were so tall that they touched the sky and clouds. Yes, and today's insects, like cockroaches, beetles, and centipedes, which you kill just with your slipper, were bigger than today's cats at that time. So, now you understand that the Earth was completely different and more powerful at that time, with 30% oxygen in the air. But what would happen if our scientists doubled the oxygen from 21% to 42% in the air through some experiments or if it increased by itself as it decreased from 30% to 21%? In this article, you'll get amazing knowledge about the importance of oxygen and how it changes with its concentration.

How was the Earth 300 Million Years Ago?

As you've understood, our Earth was completely different at that time, as the oxygen level was 30% in the atmosphere at that time. We all know that oxygen is one of the most important elements in our lives. But most of us don't know that oxygen levels directly affect our size and mass. Yes, when there was 30% oxygen in the air, the insects were so big in comparison to the present. The trees were so tall in comparison to the present. We already know very well about the size of dinosaurs. All the animals, dinosaurs, and insects lives were too long in comparison to today's animals. Some lived for more than 100 or 200 years. 

This proves that the oxygen level in the air directly affects our body size and mass. But due to asteroids, this all ends, and new lives are born on Earth very slowly. Century by century, the oxygen levels also decreased in the atmosphere, and this is decreasing now as well. You may have heard some time ago that our ancestors were taller and stronger than us. And they were smart as well, as they discovered new strategies to live in different areas.

 

The Importance of Oxygen in Everything

In human beings and animals, Oxygen is a vital element to produce glucose, red blood cells and in brain power. We know that fire is possible because of Oxygen, substance and temperature. If just for 5 - 10 seconds, Oxygen gets disappeared from our whole Earth like Oxygen doesn't exist. The Whole Earth will get destroyed in these seconds. Yes, All the buildings and homes will convert in dust because binding nature of concrete will end which is present because of Oxygen. All the planes flying in air will fall automatically. All the plants and trees will die and whole humans civilization will end in seconds.

But, the real destruction will start when Lava and fire present in Earth's Core will be silent and extinguish, then whole surface of Earth will get fall into the Core because of Gravity which will destroy the whole earth in these 5–10 seconds. Now I think you understand the importance of oxygen and its amount in our atmosphere for everyone. Now, let's imagine what will happen if oxygen directly increases from 21% to 42%.

What if Oxygen Doubled in Atmosphere

Now you know very well about the importance of oxygen and its level of concentration. As we know, our Earth was completely different in 30% oxygen. Then, what changes on Earth will occur if oxygen levels increase to 42% or more? The answers will blow your mind. There are so many advantages and disadvantages to the rise in oxygen levels. Let's know about the advantages first:

1. If the oxygen level increases in Earth's atmosphere, it will directly affect the sizes and masses of all the living organisms. Insects like beetles, centipedes, lizards, etc. will become as big as rabbits or more than them. Rabbits will become as large as dogs! Dogs and big animals will also become bigger twice or three times than now!
2. Not only animals, but humans will also become taller than now, to around 8 to 10 feet!
3. Not just our height, but our brain power and body strength will also increase by many times. Our immune system will become strong enough to defeat any bacteria or virus.
4. You will get enough energy to break world records for weightlifters and runners.
5. You will be able to perform calculations for any math problem in your mind, and you will learn everything in milliseconds.
6. Cars and bikes will be able to work without petrol or diesel.
7. Your handmade paper plane will fly for many miles!
8. Trees will become so tall that they will touch the sky and clouds.
9. Fruits and vegetables will grow larger than us.
10. Birds will look like flying dinosaurs and will become able to hunt humans.

 

Disadvantages of High Oxygen

As we know, everything has its own positive and negative sides, whether it is humans, development, or natural events. High oxygen will definitely change your life, but this will lead to extreme disasters and the end of the Earth. Now, understand the disadvantages of high oxygen levels in the earth's atmosphere:

1. High oxygen will definitely make us superhumans, but it will also harm our DNA, which will cause cancers in our body.
2. High oxygen means every bomb and missile's power of destruction will increase hundreds of times.
3. Any small, naturally produced fire will be able to destroy the whole forest.
4. Every insect and animal will start hunting humans, which will lead to a war between humans and animals.
5. Some people will start using their superminds for evil purposes.
6. Every nation will start a race to become the number one nation, which will cause irrelevant bad relationships between countries.
7. Our Earth's core heat will also rise thousands of times more than now, which will lead to volcano eruptions.
8. Then, a single atomic bomb will be enough to destroy a whole country's neighboring countries' states.
9. Aquatic species will also become larger by hundreds of times, which means whales will become as big as cities. Then, humans will become unable to travel by ship or boat.
10. At the end, all these wars and destruction could destroy our whole earth.

Summary and FAQ

Now you understand very well that there are more disadvantages to high oxygen than advantages. But you can imagine this all, as we have seen these big insects and animals in Hollywood movies. These insects and animals were present everywhere on Earth when there was 30% oxygen, and with time, their sizes reduced. The conditions stated above are all true, as they were all predicted by scientists. This is so difficult, but not impossible, to increase oxygen levels in Earth's atmosphere, and many organizations are working to maintain a balance of gases on Earth. I hope you liked this article, and you can share your thoughts in the comments. Here are some questions that could arise in your mind:

 

1. What if Earth had 100% oxygen?

Then life would not be possible for plants and trees, as they need carbon dioxide for their food.

2. Can we breathe only oxygen?

Breathing only oxygen can cause many side effects in the human body.

3. Can humans survive 100% oxygen?

Yes, humans can survive on 100% oxygen, but this can cause many side effects.

4. Do astronauts breathe only pure oxygen?

No, their tanks were filled with 70% nitrogen and 20% oxygen, and the rest were empty.

5. What if Earth had 10 times more oxygen?

Then our Earth could be different than now.

6. What if Earth lost oxygen for 1 second?

Should Earth experience a one-second absence of oxygen, the consequence would not be fatal, but there would be a momentary loss of power for all fires, internal combustion engines, cars, airplanes, and similar systems.

7. Can we plant trees on moon?

The Moon lacks a breathable atmosphere, suitable soil, and sufficient water—essential elements for supporting plant life on Earth. The significant temperature fluctuations between day and night, coupled with the absence of shielding from cosmic radiation, would probably pose challenges for the tree, potentially hindering its survival.
