Oxygen is essential for all life on Earth, and the air we breathe is about 21% oxygen. Increasing the amount of oxygen in the air to 100% would have drastic consequences, both for humans and other living things.
Effects on Humans
At 100% oxygen, humans would not be able to survive. This is because oxygen is a relatively reactive gas, and in high concentrations it can cause tissue damage. This can lead to a condition called oxygen toxicity, which can cause lung damage, as well as damage to the central nervous system and other organs.
Effects on Other Living Things
At 100% oxygen, other living things would also be affected. For example, most plants require a certain amount of carbon dioxide to survive, and at 100% oxygen, the amount of carbon dioxide in the air would be too low for them to survive. Additionally, some animals, such as fish, are adapted to living in an environment with a specific oxygen concentration, and increasing the oxygen beyond this level would be detrimental to their health.
Effects on the Environment
At 100% oxygen, the environment would also be affected. This is because oxygen is highly flammable, and an increase in the amount of oxygen in the air could lead to an increase in the frequency and intensity of wildfires. Additionally, the increased oxygen could lead to an increase in the amount of ozone in the atmosphere, which could have a negative effect on the environment.
In conclusion, having 100% oxygen in the air would have drastic consequences for both humans and other living things, as well as the environment. Therefore, it is important to keep the oxygen concentration at its normal level.
