If you mean when will the Earth run out of Oxygen, the answer is never. Oxygen is a very common element, and it's pure form in nature is O2. Normally, the air we breathe is a mixture of oxygen and other elements.
Elements cannot be destroyed in chemical reactions and therefore when we breath or burn something we are simply altering pure oxygen and putting it into another compound (Such as when when we burn Natural Gas or methane: CH4(g) + O2(g) → CO(g) + H2(g) + H2O(g)).
Oxygen is a byproduct in plants, and is found in many many chemicals such as water (H2O), so it can be put back into it's natural form through synthetic means as well. when all the trees die...

What is the proportion of oxygen in the atmosphere today?
About 21% of the Earth's atmosphere is oxygen.
What planet has plenty of oxygen?
Earth is the only planet known to have a significant amount of oxygen in its atmosphere. Other planets within our solar system either have trace amounts of oxygen or it is mainly bound up in compounds like water or carbon dioxide.
Which planet has 20 percent oxygen?
Earth
What three planets of your solar system show signs of oxygen in their atmosphere?
Earth, Mars, and Venus are the three planets in our solar system that show signs of oxygen in their atmosphere, although the levels and presence of oxygen vary significantly among them. Earth has a rich oxygen atmosphere, while Mars and Venus have much lower levels of oxygen.
Do your think will mean the end of life on earth?
The end of life on earth is speculated often when natural disasters occur. The end of an individual's time on earth comes when they die.
Effects of no oxygen on earth?
Oxygen is main gas of earth. If there is no oxygen in the earth all the life in the earth should die.
Where do you get your oxygen on earth?
we get oxygen from the trees
Why can't earth's oxygen travel through space?
Earth's atmosphere, including the oxygen, is bound to Earth by gravity.
What is the diffenerce of earth and space?
There is oxygen and gravitational force on earth but there is no oxygen and gravitational force
What percentage of the Earth's atmosphere is composed of oxygen?
About 21% of the Earth's atmosphere is composed of oxygen.
How does oxygen make life sutable on earth?
Oxygen makes it human capable of breathing in earth that's why when there is oxygen, there is life.
What percent of oxygen on the earth?
Oxygen makes up approximately 21% of the Earth's atmosphere.
Did the primitive Earth have oxygen?
No. Oxygen is not believed to have been present in the early years of Earth's history.
What percentage of oxygen is present in the Earth's atmosphere?
About 21 of the Earth's atmosphere is made up of oxygen.
Is oxygen an alkaline earth metal?
No. Oxygen is a nonmetal.
What is percentage of oxygen in earth planet?
The Earth's atmosphere is composed of about 21% oxygen. This oxygen is crucial for supporting life on Earth through processes like respiration and photosynthesis.
Was oxygen on Earth before or after life on Earth?
Elemental oxygen did not appear on Earth until some time after life did. In fact, the oxygen was produced by life carrying out photosynthesis. The first organisms on Earth were anaerobic, meaning their life processes did not involve oxygen. To most organisms like this, oxygen was highly toxic.
