Can the earth run out of oxygen?
A pair of researchers have found evidence that Earth will lose its oxygen-rich atmosphere in approximately 1 billion years. “The lifespan of oxygen-based biosignatures in Earth’s atmosphere remains uncertain, particularly for the distant future,” it said.
Why do we not run out of oxygen?
Answer. because the plants will always produce oxygen which we again use to give carbon dioxide and the plants uses that carbon dioxide and then they release oxygen. there are so much oxygen in our air which we never make it completely used.

The earth below us would disappear and we would free fall.

How did oxygen appear on Earth?
Oxygen in the form of the oxygen molecule (O2), produced by plants and vital for animals, is abundant in Earth’s atmosphere and oceans. But at some point, Earth underwent what scientists call the Great Oxidation Event or GOE for short, as ocean microbes evolved to produce O2 via photosynthesis.
