How Can We Increase Oxygen Level in the Atmosphere?

Oxygen is a vital component of our environment. It is what we breathe and is essential for the survival of animals, plants, and microorganisms. However, the current state of the atmosphere is concerning, as oxygen levels are depleting at an alarming rate. Various factors, including deforestation, pollution, and climate change, cause this depletion.

Deforestation is one of the significant causes of oxygen depletion. Trees are one of the primary sources of oxygen, and when they are cut down, the oxygen levels decrease. Reforestation is one way to increase oxygen levels: planting new trees to replace those cut-downs. This practice not only helps in increasing oxygen levels but also in reducing carbon dioxide levels, which is beneficial for the environment.

Pollution is another cause of oxygen depletion. The increased use of fossil fuels has released harmful gases such as carbon monoxide and sulfur dioxide, which can reduce oxygen levels. Reducing pollution by encouraging using cleaner energy sources such as wind and solar power is essential to increase oxygen levels.

Encouraging sustainable practices such as reducing waste and conserving water can also help increase oxygen levels. These practices can help reduce the pollution released into the environment, which can help preserve oxygen levels.

How To Increase Oxygen Level In the Atmosphere?

Increasing oxygen levels can have many benefits. Improved air quality is one of the most significant benefits, as it can reduce the risk of respiratory diseases and other health problems caused by air pollution. Higher oxygen levels can also help preserve biodiversity by creating a healthy environment for plants and animals to thrive.

There are a few ways we could theoretically increase the oxygen level in the atmosphere:

1. Plant more trees and plants. Trees and plants produce oxygen through photosynthesis, increasing forest cover, and agricultural land would have more oxygen. However, the amount of additional oxygen produced would likely be small globally.

2. Develop technology to produce oxygen through chemical or biological processes artificially. This technology does not currently exist on a scale large enough to increase atmospheric oxygen levels meaningfully.

3. Reduce the number of organisms that consume oxygen. Reducing the global human, animal, and microbial population would leave more oxygen in the atmosphere. However, this would be practically and ethically impossible on a large scale.

4. Break down water into oxygen and hydrogen. We could extract more oxygen from the water through an advanced electrolysis process. However, this would require vast amounts of energy and infrastructure.

Ways to Increase the Oxygen Level in Earth’s Atmosphere

There are a few ways we could potentially increase the oxygen level in Earth’s atmosphere:

1. Plant more trees and plants. Photosynthesis produces oxygen as a byproduct, so increasing the amount of photosynthesizing organisms would increase oxygen production.

2. Use algae farms or other technology to produce oxygen through artificial photosynthesis. Researchers are working on technologies to mimic photosynthesis and produce oxygen from water, sunlight, and carbon dioxide.

3. Reduce oxygen consumption. Reducing the number of organisms that consume oxygen, such as by reducing the human population, could allow more oxygen to accumulate in the atmosphere. However, this is not a practical or desirable option.

4. Split water into hydrogen and oxygen through electrolysis. Electrolysis involves passing an electric current through water to separate it into hydrogen and oxygen gas. However, this would require a massive amount of energy and infrastructure.

5. Release oxygen trapped in oceans, rocks, or soils. A significant amount of oxygen is trapped in compounds within Earth’s crust. However, there are no feasible ways to release that oxygen into the atmosphere at scale economically.

Oxygen is essential for all living beings to survive. It is crucial for respiration, which produces energy in our body. Without oxygen, we cannot survive for more than a few minutes. Moreover, oxygen is also essential for the atmosphere, as it helps to maintain the ozone layer, which protects our planet from harmful UV rays.

Causes of decreasing oxygen level

The primary reason for decreasing oxygen levels is deforestation. Trees absorb carbon dioxide and release oxygen during photosynthesis. However, deforestation has caused a significant reduction in the number of trees, decreasing the oxygen level. Additionally, increasing pollution levels and the emission of harmful gases by factories and vehicles contribute to reduced oxygen levels.

Ways to increase the oxygen level

Planting trees

The most effective way to increase oxygen levels is by planting trees. Trees produce oxygen during photosynthesis and absorb carbon dioxide, which helps reduce greenhouse gas levels in the atmosphere. Therefore, we should promote afforestation and reforestation programs to increase the number of trees.

Reducing pollution

Reducing pollution is another way to increase oxygen levels. Air pollution has a direct impact on the oxygen level in the atmosphere. We should promote sustainable living and reduce the use of fossil fuels, the primary source of air pollution.

Promoting sustainable living

Promoting sustainable living is also crucial in increasing the oxygen level. We should focus on reducing our carbon footprint by using renewable energy sources, reducing waste, and conserving natural resources.

Conserving wetlands

Wetlands are a significant source of oxygen. They absorb carbon dioxide and release oxygen, which helps maintain the atmosphere’s oxygen level. Therefore, we should protect and conserve wetlands, which are under threat due to urbanization and industrialization.

Protecting oceans

Oceans are also a significant source of oxygen. Phytoplankton in oceans produces more than 50% of the world’s oxygen. However, due to pollution and overfishing, phytoplankton are decreasing rapidly. Therefore, we should protect the oceans and promote sustainable fishing practices.


What is the ideal oxygen level in the atmosphere?

The ideal oxygen level in the atmosphere is around 21%. However, it can vary depending on altitude and air pollution.

Which plants are best for increasing oxygen levels?

Plants such as the Areca Palm, Snake Plant, and Money Plant are known for their ability to increase oxygen levels.

How do pollutants affect oxygen levels?

Pollutants such as carbon monoxide and sulfur dioxide can reduce oxygen levels by reacting with the oxygen in the atmosphere to form other compounds.

How can I contribute to increasing oxygen levels?

You can increase oxygen levels by planting trees, reducing waste, conserving water, and promoting sustainable practices.

What are the long-term consequences of oxygen depletion?

The long-term consequences of oxygen depletion can include the loss of biodiversity, increased risk of respiratory diseases, and other health problems caused by air pollution.


In conclusion, increasing the oxygen level in the atmosphere is essential for the survival of all living beings. We can increase oxygen by planting more trees, reducing pollution, promoting sustainable living, conserving wetlands, and protecting oceans. Our responsibility is to care for our planet and ensure that future generations breathe clean and fresh air.
